How to pick the best balls

There are no better or worse balls. All balls that are upgraded enough are good.

When making your choice, you should keep in mind the following:

1. You need to make sure that your ball level is at least the same as the number of the Alley where you play. For example, if you play on Alley 5 (Asian Drift), make sure your balls are leveled up to at least level 5.
2. There are three parameters that remain constant with ball upgrades: Guide (the higher this stat, the longer the green predict line is), Hook (the higher this stat, the more intensely a ball can hook), and Speed (the higher the stat, the faster the ball rolls down the lane). Choose the balls that suit your bowling style best.
