FourScore is a strategic combination of four arcade-style games played at once. Vertical across the top are Kossack Kubes, Space Invasion, and Dr. Pills, and spread horizontally along the bottom is BreakBricker. All four games are played simultaneously with the same controls. Your score is modified by how many games are still being played successfully, and when any three games are lost, the entire session is finished.
A puzzle game similar to Tetris. Clusters of four squares fall into a rectangular play field from the top. Form lines by moving and rotating the pieces to clear them from the grid. The game ends when new blocks will no longer fit into the grid. 0
An arcade shooter similar to Galaga, Space Invaders, etc. A block of aliens marches onto the playfield from the top, and the player's ship is located at the bottom. As ships are shot out of formation, the block of aliens speeds up. The game is over when the aliens reach the bottom of the playfield, or when one of their shots strikes the player's ship.
A puzzler similar in play to Dr. Mario. Match three cells in a row of the same color (either pill or germ) to make them disappear. When all the germs are eliminated from the playfield, the round will reset, starting with more germs. The game ends when there is no more room for new pills to form at the top center of the playfield.
An action game similar to Breakout. Keep the ball on the playfield by moving the paddle at the bottom. Bricks hit by the ball will disappear, and respawn after some amount of time. The game ends when the ball falls past the bottom edge of the playfield.
