GAMING SYSTEMS HAVING EXPECTED VALUE INDICATORS

A wagering game system includes an input device, a display device, and one or more memory devices storing instructions that, when executed by a controller, cause the wagering game system to display an expected-value indicator on the display device and receive, via the input device, an input indicative of at least one wager. The instructions further cause the wagering game system to add a portion of the at least one wager to an actual turnover for a progressive jackpot and update the expected-value indicator to indicate the actual turnover for the progressive prize relative to a theoretical average trigger value, thereby indicating a theoretical probability that the progressive jackpot will be awarded and award the progressive jackpot in response to a triggering event.
