In the game, various kinds of tetromino consisting of four blocks will fall. The aim of this game is to manipulate the falling tetromino, by moving it to the side or rotating it, so that a horizontal line will form without a gap, when it is formed, the tetromino will disappear, so that the tetromino above will fall. When the game continues, the tetromino will fall faster. The game will end when the next tetromino is blocked so it can't enter.
