Tetris

Tetris is a tetromino-based game, which draws on logical thinking, hand-eye coordination, and reflexes. The seven tetrominoes fall down the playing field. A player drops these to make unbroken lines. When a player makes one to four lines at the same time, they clear. After clearing these lines, everything over them fall. As a player increasingly clears lines, the tetrominoes fall faster. When a player does not clear enough lines in time, the tetrominoes will land nearer to the top. If dead tetrominoes cover where a tetromino spawn, the player loses.
