US Patent 8439747 Virtual playing chips in a multiuser online game network

Methods, systems, and computer programs are presented for executing game transactions in an online game to acquire virtual currency. One method includes an operation for detecting a request from a player to purchase virtual currency for use in the online game. Cash or credit is received, in an online transaction, to make the purchase of the virtual currency. The virtual currency of the online game is not redeemable for cash or credit so the virtual currency cannot be considered gambling proceeds. The method further includes an operation for crediting the player with an amount of virtual currency based on the amount of the received cash or credit.
