What makes Hercules a great game is during the free spin bonus, all your coin symbols keep their value and function as a wildly sticky coin for the remaining spins. However, during the free spin bonus round, the machine will not let you re-trigger the re-spin. A feature of all Hot Hot Super Jackpots, when the popular Super Jackpot symbol appears on the fifth reel, the Thermal Super Jackpot will be triggered on Hercules.
