Look in the menu column on the left side of the screen. Click Game status under 'Play.'
On your game status page, you will see your opponent's name in that game. Click the name.
When your game board appears, click the piece you would like to move.
On the next page, click the space to move to.
Some games require you to move more than one piece. Repeat the above steps until all available moves are completed.
When you are finished moving, click one of the 'Submit' buttons that appears beneath the game board. Once you click 'Submit' you will not be able to take back your move, so make sure it's the move you want to make.
To make a move in Go Moku, Reversi, Stack 4, or Pente, just click on the game board where you want to place your piece, then click 'Submit.'
