Adventures of Doubloon Island by Microgaming – Online Slot Review

This online slot game was created by Microgaming and Triple Edge Studios. It is the third title to come from the HyperHold series.

Click on the plus or minus sign within the Bet section to choose your wager per spin. The game starts with $0.10 and goes as high as $50. This is a relatively low betting range, giving players of all bankrolls an opportunity to play the Microgaming title. Bets dictate how much you can win, so keep that in mind when selecting your wager.

Adventures of Doubloon Island Jackpot Prizes.

The top way to win is to activate one of the four jackpot prizes. There are standard jackpot prizes you can win, or you can choose to play the Win Booster and have potential to earn more. If you use the Win Booster option, it will increase the set stake by 1.5x.

The mini jackpot offers a standard prize of 25x and 33.33x with the Win Booster. The minor jackpot is set at 100x or 133.33x with the booster. The major jackpot offers much more with 500x or 666.66x with the booster. The largest jackpot on offer is the mega, featuring 2,000x the bet in prize money or 3,333.33x with the win booster.

Special Features and Free Spins

Microgaming has added a couple of features to help you earn wins on the reels. First, we have the female pirate, which is the wild icon in the game. She can land on the reels in 1×1, 1×2, or 1×3 sizes. She is the highest paying regular symbol and offers 50x the bet with a five of a kind. If you can land a full screen of the female pirate, you earn 1,000x the bet!

The HyperHold symbol is also one you want to look out for. If you land six or more anywhere on the reels, it starts the Re-spins Strike feature. You earn three re-spins and triggering cash symbols become sticky. Any new cash symbols will stick and the re-spin total starts over at three. The re-spins will continue on the grid until you fill the screen with cash coins, or you run out of spins.

There is also a free spins feature offered in the game. Trigger the round with three treasure chest scatters. Three offers you 10 spins while four provides 15, and five provides 20. In the round, the low value symbols are removed from the grid to boost win potential for higher prizes. You can re-trigger the round, which can offer you even more free spins and win options.


Microgaming titles are known for a strong design aesthetic and this game is no exception. The grid is set in a jungle with water and a pirate ship in the background. One could imagine that the pirates have landed on the island in search of treasure. On the grid, you have a beautiful female pirate, several male pirates, gold coins, royal icons, skulls, weapons, and more. Animations and sound effects are also present, adding to the overall theme of the game.


If you are a fan of pirate themed games or the HyperHold Strike Re-spins feature, then you should play Adventures of Doubloon Island. The developer has created an exciting adventure game complete with a high RTP of 96% along with a win booster feature, free spins, wild substitutions and four fixed jackpots! Join the pirates on the reels and see what you can discover as you spin this fun online slot game!
