One player mode works fine, but Two player mode with computer does not work properly. One time it gave me (human player 1) an extra turn that could not be completed so I had to abandon the game. Another time it did not give me my last turn but still reported final scores.
Also the computer is a very poor player. For example, on its last turn it needed a only small straight and chose to keep four 4s on the first roll which obviously guarantees that it will get zero points. Computers playing logic needs to be corrected/enhanced.
