A ruling given by an appellate court in Washington states that Betcha.com is not illegal as it did not violate any state gambling laws in their operations.  Betcha.com is for gamblers who want to place bets, but  against other gamblers, not against the house.  The ruling states “Because Betcha.com customers agreed in advance that participants were not required to pay their losses, Betcha.com was not engaged in ‘gambling’”.
