A system and method for operating a game of chance. A gaming system includes a primary game display and secondary game display with the secondary game display mapped with prize blocks arranged in a grid that may generally mimic a primary game grid. The prize blocks can be represented as characters, articles, numeral values, symbols and the like. Each prize block is assigned a prize value and a health value. When the health value of a prize block is exhausted based on primary game outcomes, the prize block is destroyed and removed awarding its corresponding prize value. New prize blocks fill the void left by removed prize blocks or the void remains as a space without any assigned prize value. A bonus trigger model also serves to reduce “cold streaks” during which players may lose interest.
