I've done a little research, googled once - lol, and found out some interesting stuff about shuffleboard.
Indoor and Outdoor played on the floor or indoor on a 'table'. There are about 5 different lengths. Standard board is 22ft long and 20in wide. Official outdoor is 39ft by 6ft. Can be played by a single player but preferred by two players. Each player has 4 discs, taking alternate turns, until all discs are played. All discs remain on the board until each player has completed 4 'throws'. First to 15 points.
(this could be a good use of your collisions...)
Scoring: Do you remember the "food types triangle" diagram? Flip it upside down and place points in each section. The other system is similar to ours. But only four areas at which to aim.

One interesting 'table' I spotted.... Halfway down the table, the board does two 90 degree bends, and the 'end' of the table finishes next to player. The puck(s) will bounce off two 45 degree bumper rails. Could be fun?
It's almost 6:30am and I have finished my first coffee... Cool...
