Patent attributes
Systems and methods for providing bonus games based on positive and negative bonus accumulators are disclosed. The gaming system can generate, responsive to receiving an indication to begin a play of a game, a grid of symbols. Each symbol can have an attribute corresponding to one or more of a positive bonus value, a negative bonus value, and a credit value. The gaming system can calculate a positive accumulator value, a negative accumulator value, and a credit accumulator value based on the attribute. The gaming system can detect a condition to initiate a bonus game, and execute the bonus game based on the positive accumulator value and the negative accumulator value. The gaming system can adjust, responsive to executing the bonus game, a credit balance based on an outcome of the bonus game and the credit accumulator value.
