Gekido

From BoardGameGeek: "Gekido is a dice game in which each player controls a dragon, trying to beat other players by knocking their life dices from 6 points to zero. At each round, players rolls six 6 sided dice and try to score one of many combinations showed in his character sheet (pairs, three of a kind, four of a kind, etc), but watch out! If you fail on your gamble attempt you can hurt yourself instead of the enemy! As the battle gets more fierce, however, players would unlock new powers: when one of your life dices is reduced to zero, you gain new special abilities! The player who remains in play, knocking all opponent's life dices, wins the game."
