Swiping the screen left or right will move your piece to the left or right.

Tapping the screen rotates the piece.

You can make the piece fall faster by performing a Hard Drop or a Soft Drop

A Hard Drop is performed by quickly swiping the screen down. This will lock your piece into place and you'll be given a new piece.

To Soft Drop slowly drag down on the screen. You can still move your piece when it makes contact with another piece or the bottom of the well for a short amount of time.

You can store a piece for later by swiping up on the screen. If another piece has already been stored you will switch the new piece for the stored piece

Your piece can't be switched out the same turn it was stored
