Aim — drag anywhere on the felt to point the cue. Fine-tune with ← →, or Shift+arrows for micro-adjust.

Power — set the slider, or hold Space to charge and release to strike.

English — click the cue ball diagram. Top for follow, bottom for draw, sides for spin off the rails.

The rack — the table stays open after the break. Whoever legally pockets the first ball takes that group: solids 1–7 or stripes 9–15.

Fouls give ball in hand — scratching, hitting nothing, hitting the wrong group first, or failing to drive any ball to a rail after contact. Drag the cue ball anywhere to place it.

Winning — clear your group, then sink the 8. Pocket the 8 early, or scratch on it, and you lose the rack.
