About this game
Atomic Tetris is a two-player falling-block contest played on one keyboard. Each player arranges pieces on a separate board, and the winner is the one whose stack survives longer. Completing four rows at once adds two rows at the top of the opponent's stack.
Special tiles change the contest. To activate one, clear the row containing it before it disappears. Effects can clear your board, swap the two boards or disrupt your opponent's controls. A board swap can help or hurt, depending on which side has the healthier stack.
Player one uses R and Y to move, T to rotate, G to descend one step and 1 to drop quickly. Player two uses keypad 4 and 6 to move, 5 to rotate and 2 to descend, with Num Lock on; backslash performs the quick drop. These are the documented controls for version 1.1 and describe local shared-keyboard play.
