Rotris

Play a rotating Tetris game. Drop down blocks and make squares of at least 3x3 to remove those squares.

1. 1

   A block falls from the top - you move it left and right.

2. 2

   Rotate it if the piece needs a different shape.

3. 3

   Drop it into a gap so the top of your pile stays as flat as possible.

4. 4

   When a whole row is full, that row disappears and everything above drops down.

5. 5

   The stack reaching the top ends the game.
