Bubble Boy
Bubble Boy is an action game for the Game Master in which a small hero must make his way through hazardous stages using bubbles as both weapons and tools. Each screen presents a compact arrangement of platforms, ladders, ledges, and open spaces populated by roaming enemies. The objective is to clear the screen and reach the exit while collecting points and useful items. Progress becomes steadily more demanding as enemies move faster, platforms become less convenient, and safe routes are harder to identify.
Bubble Boy’s principal weapon is the bubble stream. Pressing the attack button sends a bubble across the screen, where it can trap an enemy or interfere with its movement. A captured foe remains suspended until the player reaches it and bursts the bubble, earning points and removing the danger. Bubbles may also be used to create temporary footholds, allowing Bubble Boy to cross gaps or gain access to higher platforms. Successful play depends on judging the distance of each shot, positioning the bubble correctly, and moving quickly before it drifts away or the trapped enemy escapes.
The stages are arranged as colorful, compact challenge rooms rather than broad scrolling landscapes. Their layouts combine open floors with narrow passages and elevated platforms, encouraging the player to use jumping, climbing, and bubble placement together. Bonus objects appear throughout the game, rewarding careful exploration and quick completion. Some items increase the score, while others provide temporary advantages that make it easier to control the screen or overcome groups of enemies. Contact with an opponent costs a life, and careless movement can send Bubble Boy into a gap or leave him surrounded.
The Game Master’s display presents the action in a bright, simplified style suited to the handheld screen. Bubble Boy is shown as a clearly identifiable figure, while enemies, bubbles, blocks, and pickups use bold shapes and contrasting colors. Animated bubbles provide much of the game’s visual character, floating upward and giving the playfield a constant sense of movement. The backgrounds remain uncluttered so that platforms and hazards can be recognized quickly, even during crowded sections.
Sound effects announce jumping, attacks, captured enemies, collected objects, and successful bursts, giving each action an immediate response. Short musical passages accompany the stages and add a cheerful rhythm to the proceedings, while faster sequences heighten the pressure during difficult encounters. The controls are direct, with movement, jumping, and bubble firing available at the player’s fingertips. Easy to begin but increasingly exacting, Bubble Boy offers short, repeatable rounds in which improved timing and a better understanding of each stage lead to higher scores and deeper progress.
Continental Galaxy
Continental Galaxy is a strategic space adventure released in 1990 by Game Master. The player assumes command of a small interstellar expedition operating on the edge of mapped space, where a chain of newly discovered worlds has become the centre of a struggle between rival powers. Each planet belongs to one of several continental sectors, and progress depends on exploring these regions, establishing bases, gathering resources, and deciding when to negotiate or engage hostile forces. The campaign is presented through a sequence of connected star systems rather than a single linear route, allowing different objectives and hazards to appear from one game to the next.
At the centre of play is the command screen, where the player allocates fuel, personnel, weapons, and cargo before sending vessels into orbit. Scout ships reveal portions of the surrounding galaxy, while heavier craft protect convoys and support planetary landings. Resources are limited, and a successful expedition requires careful planning: fuel consumed during a long jump cannot be recovered until a supply station is secured, while damaged vessels must be repaired at friendly facilities. Planetary surfaces contain mines, abandoned installations, communication centres, and enemy strongholds. Capturing these locations expands the player’s operating range and may provide access to new equipment, although some sites are defended by automated guns, patrol craft, or concealed hazards.
Combat combines tactical positioning with direct action. In space, enemy ships approach from several directions, and the player controls movement, weapon selection, and the distribution of power between shields and engines. Laser fire is accurate but drains the ship’s energy reserves, while missiles inflict greater damage and require a limited ammunition supply. Surface engagements shift to a scrolling exploration view, with the expedition vehicle travelling across deserts, ice fields, and metallic industrial zones. Terrain affects speed and visibility, and hostile installations must be approached carefully to avoid ambushes. Victory is achieved by completing the assigned campaign objectives, though poor management can leave the fleet stranded or the mission irretrievably compromised.
The visual presentation uses a bold, colourful science-fiction style characteristic of Game Master releases of the period. Star maps are marked with bright planetary icons and angular navigation lines, while the tactical displays rely on contrasting panels, status bars, and clearly separated instrument readouts. Space battles feature compact sprites, flashing weapon effects, and brief explosion animations; surface areas use repeated landscape patterns to suggest distance and scale. The soundtrack is built around electronic melodies and steady rhythmic pulses, accompanied by alert tones for incoming attacks, depleted fuel, damaged systems, and newly established bases. With its combination of exploration, resource management, tactical combat, and branching objectives, Continental Galaxy offers a demanding command experience in which every jump, battle, and planetary decision influences the survival of the expedition.
Dungeon Adventure
Dungeon Adventure places the player at the entrance to a sprawling underground stronghold filled with locked chambers, hidden passages, hostile creatures, and long-forgotten treasure. The objective is to explore the dungeon, gather equipment, overcome its guardians, and discover the route to the inner halls. Progress depends on careful examination rather than speed, as many doors, walls, alcoves, and floor spaces conceal clues or useful objects. Each new section presents a self-contained challenge while gradually revealing the history and structure of the subterranean complex.
The game uses a first-person viewpoint, with the dungeon displayed as a series of compact corridors and rooms. Movement is made one step at a time, allowing the player to turn, advance, retreat, and inspect the surroundings with precision. A command panel provides access to essential actions, including searching, opening, taking, using, and examining items. Keys, weapons, lamps, maps, and other objects must be selected at the proper moment, and some puzzles require one item to be combined with another. Keeping track of where objects are found is important, since an apparently ordinary item may provide the solution to a later obstacle.
Combat occurs during exploration when monsters emerge from the darkness or defend important locations. Encounters are resolved through direct commands, with the player choosing attacks and managing the condition of the adventurer’s equipment. Weapons differ in effectiveness, while armor and healing supplies determine how long an expedition can continue. Battles are dangerous when entered without preparation, and retreat is often the sensible choice. Ammunition, food, light, and restorative items are limited, giving every journey a measured pace and making the return to a safe area a significant part of dungeon strategy.
The visual presentation is built around dark stone passageways, wooden doors, iron fittings, staircases, chasms, and chambers lit by small pools of colored light. Objects and creatures are represented with clear, compact illustrations, while text windows identify discoveries, explain hazards, and report the results of the player’s actions. The restrained color palette suits the underground setting, using shadow and contrast to make each torch-lit room feel separate from the last. Traps, secret doors, and monster attacks provide sudden changes to an otherwise deliberate display.
Audio is used sparingly, with short effects marking movement, menu selections, attacks, discoveries, and the opening of doors. Brief musical phrases accompany important events, but silence dominates the exploration, allowing footsteps and warning sounds to heighten the sense of isolation. Dungeon Adventure rewards patience, memory, and methodical play. Its best moments come from recognizing a connection between two distant clues, surviving a difficult encounter with limited supplies, or opening a passage that transforms the known dungeon into a much larger adventure.
Falling Block!
Falling Block! is a fast-moving puzzle game from Game Master, released in 1990. The objective is simple: arrange descending blocks so that complete horizontal lines are formed and removed from the playfield. Blocks enter from the top of a narrow vertical chamber, and the player guides each piece left or right before selecting its final position. A well-placed block can clear several lines at once, while a careless drop may create gaps that become increasingly difficult to fill.
The controls are direct and responsive. The directional buttons move a falling block across the chamber, while the action button turns it to present a more useful shape. A second command sends the piece downward immediately, allowing experienced players to keep the action moving at high speed. Each block remains under the player’s control only briefly, so successful play depends on judging the available space and planning several moves ahead. As lines disappear, the remaining blocks settle downward and open new opportunities, but the speed of the falling pieces also increases.
Play begins at a manageable pace, making it easy to learn the basic formations and understand the effect of each block. With continued success, the game introduces greater pressure through faster drops and a more crowded playing area. Clearing lines earns points, with larger combinations producing higher scores. The round ends when blocks reach the upper limit of the chamber and leave no room for another piece. The compact rules make Falling Block! suitable for short sessions, while the rising speed and scoring system encourage repeated attempts to improve both accuracy and endurance.
The presentation uses a clean, functional visual style suited to the Game Master hardware. Blocks are drawn as sharply defined geometric shapes, with contrasting patterns and tones used to separate the different forms on screen. The playfield remains uncluttered, keeping the next move and the current stack easy to read even when the action becomes rapid. Score, level, and line totals are displayed beside the chamber, providing a constant record of progress. Simple transitions mark the start of a round, a successful line clear, and the final pile-up.
Audio supports the action with brief electronic effects for movement, rotation, placement, and line removal. A brighter flourish accompanies a multiple-line clear, while the game-over signal provides a firm end to the session. The music and effects remain unobtrusive, allowing concentration on the changing arrangement of blocks. Falling Block! offers an immediately accessible challenge built around timing, spatial judgment, and careful planning, with enough speed and scoring depth to keep each new game demanding.
Go Bang!
Go Bang! brings the traditional board game of five-in-a-row to the home computer, presenting a compact contest of tactics for one or two players. The object is simple: place counters on the board and form an unbroken line of five before the opposing side can do the same. Lines may be made horizontally, vertically, or diagonally, and every move can create several threats at once. A match begins with an open grid, allowing the early exchanges to develop quietly before the board becomes a tightly packed struggle for position.
The computer opponent offers a range of playing strengths, making Go Bang! suitable for both newcomers and experienced players. At the lower levels it responds to immediate dangers and leaves openings that can be exploited, while the more advanced settings examine a wider area of the board and block promising attacks before they become decisive. Two-player games use the same screen, with each competitor taking a turn to select a vacant position. The cursor can be moved across the grid and a counter placed with a single command, keeping the action brisk and ensuring that attention remains on the developing pattern rather than on complicated controls.
Success depends on more than spotting a possible row of five. Players must build overlapping attacks, force defensive replies, and judge when a harmless-looking move may lead to a winning diagonal several turns later. A blocked line is often as valuable as a completed one, and a crowded board can conceal a sudden change in fortunes. Go Bang! records the current position clearly, allowing each move to be followed without confusion, while the result is announced as soon as a winning line is completed or the available spaces have been filled.
The presentation uses a clean, uncluttered board as its principal setting. Strongly contrasting counters stand out against the playing field, and the regular grid makes diagonals and crossing lines easy to trace. Information panels show the players, turn status, and outcome, with simple graphic effects marking a successful formation. The restrained visual style suits the game’s measured pace: there are no unnecessary distractions, and the changing arrangement of counters supplies the main spectacle. Menus and prompts are direct, enabling a game to be started, restarted, or handed to another player with little delay.
Sound is used sparingly to acknowledge selections, completed moves, and the end of a contest. Short electronic effects give each placement a satisfying sense of finality, while the quiet presentation leaves room for concentration during longer matches. Games can be completed in only a few minutes, yet the increasing number of possible threats gives each board a different character. Go Bang! is consequently easy to learn but difficult to master, offering quick challenges for casual play and a deeper battle of anticipation when both sides understand the value of every square.
Hyper Space
Hyper Space places the player at the controls of a fast attack craft operating beyond the established space lanes. The objective is to survive a succession of hostile sectors while destroying enemy vessels and clearing a route through the surrounding star field. Each stage presents a continuous forward flight through deep space, with the craft moving automatically as the player guides its position, avoids incoming fire, and searches the screen for the next target. The action is immediate and uncomplicated, making accurate control and quick reactions more important than lengthy preparation.
Enemy formations approach from ahead and from the sides, often crossing the flight path or appearing in groups that demand rapid changes of direction. Hostile craft vary in movement and firing patterns, and allowing them to pass unchecked can leave the player surrounded or exposed to repeated attacks. The ship’s weapons are controlled directly during flight, permitting sustained fire against approaching targets. Successful hits add to the score, while collisions and enemy shots reduce the craft’s remaining strength. The display keeps the main action clearly visible, with information panels providing the current score and other essential status details.
The journey is divided into increasingly demanding sections, with later areas requiring greater precision as enemy movement becomes faster and the screen grows more crowded. Space itself is presented as a dark field scattered with bright stars, creating a strong impression of speed as the background streams past the player’s vessel. Enemy craft and projectiles are drawn in sharply contrasting colours, giving them an immediate presence against the blackness. Explosions and impact flashes provide clear visual confirmation of a successful attack, while the limited size of the play area keeps every movement significant. The overall presentation is compact and functional, concentrating attention on the flight corridor and the threats within it.
The audio follows the direct, arcade-style design of the game. A driving electronic sound accompanies the action, with short effects marking weapon fire, enemy destruction, collisions, and other changes in the battle. These sounds help identify events during periods of heavy activity, when several ships and missiles may occupy the screen at once. Hyper Space is built for repeated attempts: an early run establishes the enemy patterns and control response, while later games depend on tighter movement, more economical firing, and a willingness to take risks for a higher score. Its simple controls, rapid pace, and steadily increasing pressure make each sortie brief, demanding, and easy to begin again.
Kung Fu
Kung Fu places the player in control of a lone martial artist advancing through a series of hostile locations. The objective is to fight through each stage, defeat the opponents guarding the route, and reach the final confrontation. The action follows the familiar traditions of arcade kung fu, with the hero facing enemies from both sides while moving steadily across the screen. Progress depends on quick reactions, careful positioning, and a willingness to attack before an opponent can close in.
The fighter’s basic moves include punches and kicks delivered at different heights, allowing attacks to be aimed at standing or crouching opponents. A well-timed blow can interrupt an enemy’s advance, while careless button pressing leaves the player open to a counterattack. Enemies approach in groups and use varying speeds and attack patterns, making it important to watch the entire playfield rather than concentrate on a single combatant. Advancing too quickly can result in being surrounded, but hesitation gives additional opponents time to appear.
Each section presents a compact martial-arts challenge built around movement and timing. The hero must cross the area while dealing with attackers, avoiding contact, and finding safe moments in which to strike. The scenery suggests a succession of traditional training grounds, courtyards, passageways, and fortified interiors, giving the journey the atmosphere of a lone warrior entering an enemy stronghold. Obstacles and changes in the surroundings help distinguish one stage from the next, while the steady arrival of new opponents keeps the pressure constant.
The graphics use a clear, functional presentation suited to the close-range combat. The protagonist is shown in a compact martial-arts stance, with separate animation frames for punches, kicks, crouching, and movement. Enemies are given recognizable silhouettes and contrasting colors so that their positions remain easy to read during a crowded battle. Backgrounds are assembled from simple architectural details, dark interiors, walls, floors, and decorative features associated with an eastern martial-arts setting. The emphasis is on visibility and immediate response rather than elaborate scenery.
Sound effects provide the sharp impact of punches, kicks, and enemy attacks, reinforcing every successful exchange. Short musical passages and electronic accompaniment establish an energetic arcade mood without distracting from the action. The controls are straightforward, yet the increasing number and variety of opponents make Kung Fu progressively demanding. Success comes from learning the reach of each attack, keeping the hero correctly aligned with approaching enemies, and maintaining a steady rhythm. Its direct rules and fast rounds make the game easy to begin, while the later stages provide a stern test of reflexes and concentration.
Move It
Move It places the player in control of a small animated mover whose task is to clear a series of compact, single-screen puzzle rooms. Each screen is arranged as a tile-based layout of platforms, barriers, switches and movable objects. The route to the exit is rarely direct: crates must be pushed into useful positions, passageways opened and isolated sections of the room reached in the correct order. A move made too early can block a corridor or trap an object against a wall, so every stage rewards careful planning rather than quick reactions.
Movement is controlled one step at a time, with the character travelling horizontally and vertically across the available spaces. Objects respond according to their position and the direction in which they are approached. Some can be pushed across open floor, while others must be used to hold down pressure pads, activate gates or provide a bridge over hazardous areas. The screen normally remains fixed while the puzzle is solved, allowing the entire layout to be studied before action begins. Completion comes from reaching the exit after arranging the room correctly, and later stages introduce tighter spaces and combinations of obstacles that demand increasingly precise movement.
The game’s setting is presented as a colourful mechanical world of working rooms, storage areas and industrial passageways. Pipes, panels, blocks and marked floor sections give each location a clear functional purpose, while the compact layouts keep the emphasis on solving the puzzle rather than exploring a large landscape. Bright backgrounds and strongly contrasting objects make interactive elements easy to identify. The mover is given a simple, distinctive appearance and a lively walking animation, with directional changes and object pushing clearly shown on screen.
Move It uses a clean, uncluttered display suited to its puzzle design. The current room occupies most of the screen, with the score, stage information and remaining attempts shown separately so that they do not interfere with play. Colours distinguish solid walls from usable floor and dangerous spaces, and animated gates, flashing switches and moving sections provide immediate visual confirmation when a solution begins to take shape. The uncomplicated presentation also makes the rules of each new room apparent without lengthy instructions.
Audio is used sparingly but effectively. Short electronic effects accompany movement, pushing, switch operation and the opening of exits, while a brighter success sound confirms the completion of a room. The music and effects give the game an energetic arcade character without distracting from the concentration required by the puzzles. Move It offers a steadily testing solo challenge, beginning with straightforward arrangements before demanding foresight, patience and an understanding of how each object affects the rest of the room.
Pin Ball
Pin Ball brings the familiar arcade table to the Game Master in a compact, fast-moving display. The playfield occupies the full screen, with the ball entering from the upper section and descending through a maze of walls, bumpers, targets, and lanes. The object is to keep the ball in play as long as possible, striking the table’s scoring features and building the highest total before all available balls are lost. A pair of flippers at the bottom provides the player’s main control, demanding quick timing and careful attention to the ball’s changing path.
The flippers are operated independently, allowing shots to be directed toward either side of the playfield. Each contact with a bumper sends the ball away at a new angle, while the surrounding guides and barriers shape its movement into unpredictable rebounds. Targets and marked scoring areas reward accurate play, and the upper portions of the table offer greater opportunities for points when the ball can be guided back into them. The narrow lower lanes remain the constant danger: once the ball passes between the flippers, only a limited number of attempts remain.
The Game Master screen presents the table in a crisp, highly contrasting style suited to the handheld display. The playfield is arranged with clearly defined borders, posts, bumpers, channels, and flipper shapes, making the important areas easy to recognize even while the ball is moving rapidly. Small changes in position and direction are central to the action, and the simple graphical presentation keeps the focus on the ball, the flippers, and the current score. The result is an uncluttered arcade layout that can be read at a glance.
Sound effects provide immediate confirmation of every important event. Bumper strikes, target hits, and other collisions are accompanied by short electronic tones, while the loss of a ball is marked by a distinct signal. The effects are economical but effective, giving the table a steady rhythm as the ball ricochets from one feature to another. Score changes and play events are presented through the Game Master’s straightforward electronic display, maintaining the quick, functional character of an arcade machine.
Pin Ball is simple to begin but increasingly demanding as the player attempts to control longer rallies. Success depends on judging the ball’s angle, choosing the correct flipper, and resisting hurried movements when the ball approaches the drain. Each game is brief enough for repeated attempts, yet the constantly changing rebounds ensure that no two runs develop in exactly the same way. Its direct controls, brisk action, and emphasis on score make it a natural choice for short sessions or determined attempts to master the table.
Soccer
Soccer brings association football to the Game Master in a compact, immediately accessible format. The action is presented from a high, overhead viewpoint, with the pitch filling most of the display and the goals positioned at opposite ends. Small, clearly differentiated player figures move across the field while the ball remains the central focus of play. The limited screen area creates a fast, concentrated contest in which possession can change quickly and every opening toward goal must be used carefully.
The player directs a team through the Game Master controls, moving the active footballer around the pitch and using the action button to perform the principal moves. Passing allows the ball to be advanced between members of the side, while a further command sends a stronger kick toward the opposing goal. Direction and timing are important: a poorly aimed pass may be intercepted, and a shot taken from too far away can be easily dealt with by the defending side. As possession changes, control shifts to the appropriate player, requiring constant attention to the position of the ball and the movement of teammates.
Matches follow the familiar rhythm of football, beginning with a kickoff and developing through attacks, defensive recoveries, and attempts on goal. The two sides advance up and down the field, with the computer-controlled team applying pressure and seeking opportunities of its own. Defending depends on moving into the path of the ball, closing down the opponent, and preventing a clear run toward the goalmouth. The goalkeeper occupies the most important defensive position, making the final save when an attack reaches the penalty area. Success comes from combining accurate movement with quick decisions rather than simply holding the action button.
The visual presentation is deliberately simple, using a small number of colors and bold, easily recognized shapes suited to the Game Master screen. The green playing surface, field markings, goals, and player sprites establish a complete football ground without unnecessary decoration. Scrolling keeps the important portion of the pitch visible as play moves forward, while the scoreboard provides a clear indication of the current result. The uncluttered display makes the ball and active players easy to follow, even when several figures gather around the same area.
Audio consists of brief electronic tones that mark the principal events of a match. Kicks, changes of possession, and scoring chances are accompanied by sharp sound effects, giving the action additional definition without distracting from the play. The result is a straightforward handheld football game built around quick matches and uncomplicated controls. Soccer offers the essentials of the sport—movement, passing, shooting, defending, and scoring—in a form that can be learned rapidly while still rewarding careful positioning and well-timed attacks.
