Tetris

The Game Boy version of Tetris plays identically to versions of Tetris released on other platforms. A pseudorandomsequence of "tetrominos" -shapes composed of four square blocks each - fall down the playing field. The object of the game is to manipulate these tetrads, by moving each one sideways and rotating it by 90 degree units, with the aim of creating a horizontal line of blocks without gaps.The player can normally see which block will appear next in a window off to the side of the playing field, but this feature can be toggled during the game. Points are awarded based on the current level and the number of lines cleared, and the level increases each time the player clears ten lines.


When one or more such lines are created, they disappear, and the blocks above (if any) move down by the number of lines cleared. As the game progresses, the tetrominos fall faster, and the game ends when at least part of a tetromino extends beyond the top of the playfield when set in place.
