So I’ve been working on polishing Bowlmaster and I had a question about ending the game. I’m having trouble figuring out where I should stop the game? Should I stop at 20 rolls? 21 rolls? The 10th frame? A little confused here.
Help would be greatly appreciated.
Great question! Looks like you may have a few possibilities…
Hope these help 
Just in case reading up on the rules doesn’t help, the game always ends in the tenth frame, but how well you bowl in the last frame determines if you roll 2 balls or 3. Basically if you knock over every pin within 2 balls in the tenth at least once you get the extra ball
I ended up just ending the game as you suggested, in the 10th frame. Using ScoreDisplay’s frames.Count = 10 then the game displays a popup that ends the game.
