==Gameplay==

In its most basic form, gameplay consists of a small contained area that fills up with random falling tetrads – blocks consisting of four squares in varying configurations. The player can move the blocks horizontally, rotate them 90 degrees, or speed up their ascent. The object of the game is to earn points by forming lines across the bottom of the play area, causing them to be destroyed. More points are awarded depending on how many lines are destroyed at once. When the lines destroyed reach a certain threshold (usually ten), the rate at which the blocks fall will increase, and the player moves on to the next level. If enough blocks accumulate beyond the top of the screen, the game ends.
