I like Triple Gammon, a great new refreshing type of tournament. That gave me another idea for any game that uses highest points to win (like Froglet, Assimilation and Mancala, or even Anti Backgammon):

Round Robin, two standard games per player:
Instead of scoring one point, players score points equal to the outcome of te game. E.g if a Mancala game ends in 30-18, player A scores 30 points to his total and player B scores 18. BKR resolution as normal. If all games are finished, count all points scored in all matches, highest wins.

This way of playing destroys Mancala and Cheversi advantage, since every player is White AND Black against every other player, trying to score as most points as possible.
