Here is the video game 'Mah Jongg Solitaire'! Released in 1987 on DOS, it is still available and playable with some tweaks. It is a puzzle game, set in a card and tile theme.
The objective of this game is to kill all the flies. This is done with a fly exchanger, controlled with the mouse cursor. Each time the fly swinger is next to a fly, the fly dies and becomes a dead, indestructible object. The fly exchanger cannot move across a dead fly; neither can live flies. Each level has preset walls and bonuses. A bonus can mean that instead of a fly exchanger, the user controls a spray to make dead flies disappear instead of becoming indestructible objects.
