Rule highlights

Setup, play, winning, and house rules

Setup

  • Rack the balls in a diamond and break.

How to play

  • Drag on the table to aim. Pull the left power gauge down and release to shoot; pull farther for more power, or move sideways to cancel. Fine aim helps adjust the angle in small steps.
  • Hit the lowest remaining number first; you may then pocket any numbered ball.
  • Continue if a ball is pocketed; otherwise change turns.
  • Scratching, hitting the wrong ball first, missing every ball, having no rail or pocket after contact, or knocking a ball off the table is a foul.
  • After a foul, the opponent places the cue ball anywhere. Respot the 9 if pocketed on a foul.
  • Running out of time is also a foul.

Winning

  • Legally pocket the 9 ball to win.
