You MUST play the ENTIRE game and beat the computer.
This game will use The Special Blowout Rules for final score, where it is tabulated by how many points you have won the game by. [Ex. If you beat the computer 12-2, your final score will then be 10, which is how much you won by.]
The score rolls into symbols after 15, so points over 15 must be counted manually by a referee.
