BUMPER POOL RULES AS I RECALL THEM

The balls are lines up on the opposite end of the table from the 
corresponding hole (e.g., the white balls go on the end with the red 
bumpers around the hole).  The spotted ball is lined up in front of 
the pocket, about 1" out.  The other balls are spaced evenly between the
side rail and the middle (2 on either side), about 1" from the bottom rail.

It's a simultaneous start - we used to just count to 3, and on 3, both 
players shoot the spotted ball, trying to bank it into the pocket on the 
other end (so all the red balls will go in the red pocket). 

If neither player makes their ball, the one closest to the pocket shoots
first.  If one makes it and the other doesn't, they get to shoot any of their
other balls towards their pocket.  If both players sink their balls, they
each take one from their remaining 4 (usually the same ball), place it in 
front of the hole where their spotted one was, and they start again.  

NOTE:  You CAN NOT shoot any of your other balls until you sink your
spotted ball.  Your opponent gets to drop one of theirs (pick it up and
drop it in the pocket) if you do.

Penalties:  If you accidently shoot one of the other player's balls (red 
player shoots a white ball), your opponent get to drop one of theirs in 
the pocket.  If you accidently MAKE one of theirs, though, they don't get to.
(Your penalty is giving them the ball).  If you shoot one of your unspotted
balls before you make your spotted one, they get to drop one.  If you make
one of yours illegally (drop it in the wrong pocket), they get to drop 2
balls.  

Strategies:  If you like playing defense, use your shots to keep them away
from a clear shot at the pocket, or leave one of yours in front of their 
pocket.

That's it as far as I recall.  We had an actual rulebook, and this is how
it was played.  I hope it helps, and if you have any more questions,
just e-mail me.
