Originally released for MS-DOS in 1991, Supaplex is a tile-based puzzle game similar to Boulder Dash. Move your character around the map as you remove circuit boards, avoid hazards, and collect objects called infotrons. When you collect enough infotrons, you will receive stars and unlock the exit. Be careful when removing circuit boards adjacent to round stones. If a stone is unsecure, it will roll or fall. Stones can be pushed, but if one falls on your head, the game is over!
