Bonus Features

Win Booster

This opt-in feature increases your wager by 1.5x in exchange for multiplying your Hyperhold wins by 3x and any jackpot wins by a maximum of 2.5x.


Landing 6 or more doubloon symbols will trigger the Hyperhold feature where the game grid will empty itself of symbols, except for the triggering doubloons which will remain locked in place. You will have 3 respins to try and fill the empty positions with doubloons, if any appear, your respin count will be reset to 3 and the feature will end once you have filled all the vacant positions or your respins finish.

Once the round is over, the symbols will reveal cash prizes worth up to 50x or 100x with the win booster off or on. You could also claim the Mini, Minor, Major, or Mega jackpots worth 25x, 100x, 500x, or 2,000x your wager, respectively, with the Win Booster off, or 33.33x, 133.33x, 666.67x, or 3,333.33x your wager, respectively, with the Win Booster on.

Free Spins

Landing 3, 4, or 5 scatters on the reels will award you 10, 15, or 20 free spins, respectively. No low-paying symbols will appear while the feature is active and landing 3 or more scatters will retrigger it.

Our Verdict

Adventures of Doubloon Island slot trades on tried and tested features to bring you a swashbuckling slot experience. The slot’s visual theme is richly detailed, juxtaposing the gritty pirates with the lush beauty of the island. Hyperhold is the game’s dominant feature, delivering sizeable wins when activated and paying out even more when the Win Booster is active. Free spins give you the chance at high-value symbol combinations to boost your winning chances. With a top winning potential of $100 000 (or $250 000 with the Win Booster activated) his isn’t the richest slot out there, but it delivers entertainment value in spades.
