This present pari-mutuel invention provides for a network of table games and real time electronic devices operating slots, poker, keno, bingo and other games. Players compete against other players for non-banked prizes which are paid only from player pools. Player pools start with a balance of zero. The player pool receives one hundred percent (100%) of player bets, less appropriate rental fees. Posted prizes cannot exceed the player pool. The player receives dynamic displays of the pool balance and corresponding posted prizes. A top prize feature prevents the pool from dropping back to zero. The house receives a fee from players who rent a pari-mutuel device. The house does not seed the pool with money, nor take any money from it. The devices can operate in a stand-alone-mode with local player pools under local control. However, they have linked access to a network controlled by a central management system to receive the benefit of centralized Player pools. Pari-mutuel devices can switch to a "stand-alone-mode" using the local pool. This may be desirable when the central pool becomes unavailable for any reason, or simply if stand-alone-mode is preferred.
