A reversi online game. After you and an opponent have joined a game of reversi you may go to it any time by clicking your opponent's name as it appears on your game status page. If it is your turn, when you see the game board a blue outline is shown around the pieces that were changed in your opponent's last move.
To make your move, click a space where you want to place a piece. You must place a piece where it will capture one or more of your opponent's pieces. A new page will load showing your new piece on the board and the captured pieces turned to your color. Then, you must click one of the 'Submit' buttons at the bottom of the page to submit your move. If you don't want to submit it and you want to make a different move, click 'Take back the move.'
