A method for wagering comprises receiving a bet regarding a spin of the reels of a slot machine. The method continues by determining a first value for a first reel of the slot machine based at least in part upon the value of a digit of a first financial market indicator. The method proceeds by determining a second value for a second reel of the slot machine, and by determining a third value for a third reel of the slot machine. The method concludes by determining the outcome of the bet based at least in part upon the first value, the second value, and the third value.
