Mambo, when I can find someone to play, we played that way.we used to play some kind of 3cushion on a pool table 10 years ago.
1 point for a 3cushion carom legal hit
1 extra point for potting the first ball you hit
or 1 extra point for potting for hitting the last ball
or 5 points for potting the 2 balls on a legal 3cushion carom shot
