A computer-implemented method that includes programming a computer machine to perform the steps of: providing game slips to game players, where each games slip has game options and one of the game options is a first game option that includes a non-verified outcome of an event; receiving the game slips that include selected game options where one selected game option includes the first game option; determining odds of the first game option based on: 1-P, where P is the probability of a verified outcome of the event, a financial criterion of the game provider, and the selected game options; providing and receiving acceptance of the odds; determining whether the event has resulted in the verified outcome or the non-verified outcome; and determining, for each game player that selected the first game option, a prize based on the accepted odds when the event results in a non-verified outcome.
