Abstract: Method and systems are provided for using electronic game-pieces or e-tokens in games of chance. Electronic game-pieces allow players of games of chance to participate in real-time in games of chance, to effect real-time wagers, to dynamically adjust the players' odds of winning, and to re-use or create combinations of game-pieces to increase players' odds of winning or players' odds of winning different prizes. Multi-player games are also described in which multiple players may engage in cooperative or competitive wagering or game play.
