Eight-ball
The table is open after the break. The first ball you pot legally claims solids (1–7) or stripes (9–15) for you.
Keep shooting while you keep potting your own group.
Potting the last of your seven does not end your visit. You stay at the table, call a pocket for the black — tap the pocket you are going for — and play on.
The black is one attempt. A spare shot never carries onto it.
Put the 8 in the pocket you called and the rack is yours.
The rack is only lost on the black going down when it should not — potted early, potted in a pocket you did not call, or potted on a shot you fouled. Everything else while you are on the black — missing it, a scratch, taking one of your opponent's — is an ordinary foul: two shots to them, and the game plays on.
Fouls & two shots
A foul hands your opponent two shots — two visits at the table, so they can miss once and still play on. Potting keeps the spare shot in hand. This does not apply once a player is on the black.
It is a foul to: pot the cue ball, strike the other group first, strike the 8 first when you are not on it, hit nothing at all, fail to send any ball to a cushion when nothing is potted, or pot one of your opponent's balls.
The cue ball is played from where it lies — except after potting the cue ball, when it comes back in hand behind the head line.
Points
Every ball of your own group is worth 10. Winning the rack is worth 100.
