Dodeccamente (1989)

Dodeccamente from my cursory read of the rules appears to be a Backgammon variant set upon a circle. It allows for up to 6 players to play and uses 3 dice instead of two, which dramatically increases the complexity. You still split how the dice move pieces just as in Backgammon (although with a few additional constraints), and you send pieces back to "start" just as you do in Backgammon.
