Accordingly, a gaming device can be configured to roll multiple virtual dice on a game display and determine if the result of the dice roll satisfies a predefined criterion. When the result of the initial dice roll satisfies the predefined criterion, one or more of the multiple virtual dice is re-rolled. The gaming device then evaluates a game result after the re-roll, where the combination of the displayed faces from any initially rolled dice that were not re-rolled and the displayed faces from the re-rolled dice are used in the evaluation. ## Claims ### Claim 1 A gaming device comprising: a game display for displaying game events;
