Blokus can be played either on your own with computer-controlled opponents making up the numbers, offline with up to three of your friends, or with other PlayStation 3 players via PlayStation Network. Don't forget, if you're playing with friends in offline mode, you'll need additional wireless controllers or motion controllers.
You move pieces using the left stick on the wireless controller, and press the L1, L2, R1 and R2 buttons to rotate and flip them before placing them in position. Once you have positioned your piece, press the X button to drop it into place. If you need to switch the piece you're using for another one because you can't find the right spot for it on the board, quickly press the Circle button and choose another block from the selection available to you.
When using PlayStation Move to play Blokus, you move the blocks around the board by picking them up with the Move button on the motion controller. Once you have a piece in your grasp, move it around the board and into position before pressing the Move button again to lock it into place. You can also rotate the blocks by tilting the PlayStation Move controller.
