Rules can vary slightly from game to game, but here's how we play our weekly (actually ends up being 2 or 3 times a week) ring game.
Winner breaks
small money on the 5, big money on the nine (small and big are relative, $1 and $2, $2 and $3, $3 and $5, $5 and $10, etc)
If the 9 goes in before the 5 is cleared off of the table, it spots back up.
If the breaker scratches, then all balls made on the break spot back up. If no balls are made and the lowest numbered ball is behind the headstring, it spots on the footspot.
No BIH on fouls. Next shooter after a foul has the option of shooting the shot or making the fouling player shoot again.
On a scratch, or any cue ball foul, all balls made on the foul spot on the footspot.
Other than normal 9-Ball rules, that about covers it, I think.
Have fun,
Bob
