Bonus features

HyperHold Bonus

Each HyperHold symbol that lands is collected in the HyperHold meter and reset on each spin. 6 to 14 HyperHold symbols in any position trigger the HyperHold Bonus feature. Each HyperHold symbol awards a cash prize or reveals a jackpot. The feature begins with 3 respins. All triggering symbols are held on the reels. Each unheld symbol’s position spins independently. Respins have special reels with HyperHold symbols and blank positions only. All additional HyperHold symbols that land are held on the reels, and respins are reset to 3. The feature ends when no respins remain or when 15 HyperHold symbols are held on the reels. The HyperHold Bonus can be triggered in the base game and Free Spins.


Win Booster

The Win Booster increases the jackpot and cash prize values. The Win Booster also allows Mega to be awarded by the skull doubloon symbol. The Win Booster increases the bet by 1.5x, and does not affect line pays.


Free Spins

Low symbols are removed in Free Spins. 3, 4 or 5 scatters trigger 10, 15 or 20 free spins respectively. Landing 3, 4 or 5 scatters during Free Spins will award 10, 15 or 20 additional free spins. All bets during Free Spins are the same as the triggering spin.



Wilds substitute for all symbols except scatters and HyperHold symbols.



Scatters pay in any position. Scatter wins are added to line wins, and wins are multiplied by the total bet.
