Adventures of Doubloon Island Slot Review

Three pirates and a parrot are probably the best team to accompany you should you wish to have any luck searching for hidden treasure chests full of doubloon coins and gold. Fire up the Adventures of Doubloon Island slot machine to begin your treasure hunt, which could lead you to any of four money-spinning jackpots.

Rich Mateys Play Like Pirates

In the Adventures of Doubloon Island slot machine, Microgaming and Triple Gold Studios combined some killer graphics and some fantastic bonus features to tell a pirate story. You get a little of almost every pirate story you’ve ever heard, from Treasure Island to Pirates of the Caribbean. The backdrop oscillates between an island’s beach and a cave full of treasure, and the soundtrack occasionally crescendos during successive or big wins to level up the excitement.

Microgaming’s presentation of Adventures of Doubloon Island online slot is simple yet pleasantly sophisticated. You’ll encounter a red pirate captain, a scary violet pirate, a pair of cutlasses, and a parrot as the higher paying symbols. Lower paying symbols on the flip side are four poker card suit symbols, namely spades, diamonds, clubs, and hearts presented as gemstones. The lady pirate tossing her flintlock pistol is the wild, and a treasure chest is the scatter. There are two more symbols – a golden skull with crossed cutlasses and doubloon coins that trigger the HyperHold feature, which we shall discuss later in our Adventures of Doubloon review.

A Good Loot for You and Your Crew!

The Adventures of Doubloon Island slot machine is a 5-reel 3-row slot featuring 20 paylines where you can bet any amount between 0.10 and 75 coins if you activate the Win Booster and 0.10 and 50 coins without it. It also comes with a high RTP (96.01%), high volatility combination where all symbols except the HyperHold icon will pay out a prize. Here’s a highlight of the paytable to give you some insight into how the characters will pay you out when you play Adventures of Doubloon Island slot online:

Three on a Payline
Four on a Payline
Five on a Payline
Heart, Diamond, Club
Cutlass Pair
Violet Pirate
Red Pirate Captain
Treasure Chest (Scatter)

Bonus Features to Boost Your Treasure Hunt

Given the high volatility, Microgaming had to cool things down with a couple of bonus features, which are highly rewarding if you get a hold of them on the grid. They include:

  • HyperHold Feature

Landing 6 or more doubloon coins or skulls in the Adventures of Doubloon Island slots game will unlock the HyperHold feature. Here, whichever symbols triggered the feature are held in position, and you have 3 spins to try and get as many of those symbols as you can on the reels. Any extra symbols landed will reset the respin value back to 3 to increase your chances of filling the reels with the active HyperHold symbol. The values on the symbols will be summed up to pay you a handsome loot!

  • HyperHold Jackpots

During the HyperHold round, when you play Adventures of Doubloon Island slot online, you can activate any of four jackpots. You’ll unlock the Mega Jackpot if you manage to fill all reels with the HyperHold symbol, while the Mini, Minor, and Major Jackpots are randomly awarded when skulls are captured during the round as follows:

• Mini Jackpot - 25x your bet 

• Minor Jackpot - 100x your bet 

• Major Jackpot - 500x your bet 

• Mega Jackpot – 2,000x your bet

  • Win Booster Feature

Activate the Win Booster to raise your total stake per spin by 1.5x and increase your chances of winning big and unlocking the HyperHold feature much sooner in the game. The other perk of the Win Booster is that you could end up winning the Mega Jackpot even if the reel has not been populated with HyperHold symbols.

  • Free Spins

3, 4, or 5 scatters on reels will trigger a free spins round with 10, 15, or 20 free spins, respectively. Line up at least three more scatters in the Adventures of Doubloon Island online slot to retrigger the free spins round.

  • Expanding Wilds

The lady pirate wild expands to 2 or 3 positions on a reel and substitutes for all symbols except the scatter, tremendously giving you an edge in creating winning combinations.
