About this app

Pool Rules is the complete, portable reference for eight billiards games.

- Eight Ball
- Nine Ball
- Ten Ball
- One Pocket
- 14.1 Straight Pool
- Bank Pool
- Rotation
- K-Ball

Rules for the six classic games are sourced directly from the three major governing bodies — WPA, CSI (BCAPL/USAPL), and APA — plus traditional and community-sourced rules for Rotation and K-Ball. Switch between rulesets with a tap to see how the rules differ across organizations. Sections marked with a star highlight the key differences between your default ruleset and the one you're viewing.

Dark mode and light mode supported. Go ad-free with a one-time purchase.

Perfect for players, referees, and anyone who wants to settle a rules dispute at the table.

What’s new

New: K-Ball and Rotation games added! We also reviewed every ruleset for accuracy against official WPA/CSI/APA rules, tightened the wording, and refreshed the Spanish and Portuguese translations throughout. Thanks for playing!
