Bonus
There is no wild symbol, but the slot does come with a scatter symbol. Hades’ chair is the scatter symbol of the slot. It can appear on all reels, and if 4 lands on the reels in a single spin sequence then the bonus is triggered, and you receive 15 free spins.
Bonus Buy Battle Feature
The Bonus Buy Battle is a fun game mechanic where you can face off against Billy the Bully in a winner takes all challenge. After buying into the battle, you can choose one of two slot options, and Billy will get the other. Then, you and Billy will take spins in your bonus rounds and aim for the highest payout. If your winnings in the bonus round are higher than Billy’s, then you win the total combined for both your rounds. And if there is a tie-breaker, you automatically receive the total combined winnings.
Bonus Buy Option
The slot comes with three bonus buy options where you can choose which feature you want to activate. The feature and your bet size determine the cost of the feature.
Bonus Boost – Activate a double chance of triggering the Bonus Round (1.2x your bet)
Bonus – Enter the bonus with 15 free spins (100x your bet)
Bonus Buy Battle – Battle against Billy in the Bonus (100x your bet)
