Chess: The chess program is extremely stable. No errors have been reported in our ftware for a long time. If you cant move the piece you want to, it might be because the move you are trying to make is not legal. Things to look for: Are you currently in check Or, would the move would result in you being exposed to check (look at the pieces in ine with the king behind the piece you want to move) Battleboats Plus: If the SUBMIT utton is not appearing after you make your move, it means that you have more moves to ake. In Battleboats Plus, you get one shot for every ship of yours that isnt sunk yet. What this means is that at the beginning of the game you have 5 shots to make. The SUBMIT button wont appear until you take all 5 shots. Checkers: The rules of checkers state that if you have a jump available, you must take it. If our system does not let you select a piece to move, check to be sure that another piece doesnt have a jump available,
