Reconciling payback percentage of a gaming device with transferable return

Abstract

An electronic gaming machine (EGM) is configured to run a persistence game having one or more recordable persistence states transferable to another EGM. The EGM includes a logic system, a computer readable memory including instructions executable by the logic system for running on the EGM a persistence game having persistence states leading to a persistence award redeemable when persistence criteria are satisfied, each persistence state having a persistence value representing a portion of the persistence award, a verification interface configured for determining whether to initiate play of the persistence game at a previously recorded persistence state, a coin-in meter, a coin-out meter, and a theoretical coin-out meter storing in the memory unawarded persistence values accumulated by the machine from advancing the persistence game during game play among the one or more persistence states, and calculating a value for theoretical coin-out as a sum of the accumulated coin-out value and a difference between the persistence value of a current persistence state and the persistence value of a previous persistence state.
