ADD EM UP
Played as regular bowling except you cannot get a 0 in frames 9 or 10.
You must knock down at least 1 pin each frame.
If you don't, you will DQ for that round.
At games end, add the digits of your total score to get your new score. Example 123= 1+2+3= 6.
If both players DQ in the same frame, continue to bowl.
If neither DQ's, high score will win round.
