The host computer stores the wager data and generates a first hash value for the wager data at a time prior to drawing the winning game elements. The host computer is capable of generating a second hash value for the wager data at a time subsequent to drawing the winning game elements for comparison to the first hash value. The verification device receives the first hash value for the wager data prior to drawing the winning game elements and receives the winning game elements.
