How Pin-Baseball works: Each game is set on one ball per game and have a scoring chart that determines whether you get an out, a single, double, triple, or home run. The maximum number of bases for a ball is 4 (home run). After you achieve a home run score on a ball, you can stop playing that ball. Whatever amount of bases you achieve in a ball, you look at the scoring chart and mark out, single, double, triple, or home run. Start a new game and repeat until you reach three outs and end the inning, or you’ve exhausted all of your batters (9 balls). Example for Iron Maiden: Out - < 30 million Single – 30 million Double – 60 million Triple – 100 million Home Run – 200 million Let’s say… On batter 1 you score 168,570,340. You would get 3 bases (triple) and get a runner on third base. On batter 2 you score 37,344,650. You look up what 37 million equals and see that it scores a single so you mark a single. The runner on third base makes it home for a run. On batter 3 you score 7,223,203(ouch!). 7 million is less than the single score, so you get an out. On batter 4 you get 20,435,330. Also an out. On batter 5 you get 15,004,330. Your third out, and your inning is done. Alternatives: In an arcade setting you probably don't want to only play 1 ball per game. This can be fixed by switching to Per-Game scoring. It will then take one three-ball game to determine an out, single, double, triple, or home run. I'd recommend only playing one inning if doing this ;) You could also do math in between balls instead...
