How to Play the Adventures of Doubloon Island Slot Machine

Microgaming has been at the top of the online slots market since they opened the very first internet casino in 1996, so they have decades of experience. It really shows in their games, which are easy to set up, but offer plenty of thrills. The Adventures of Doubloon Island slot sets the reels against a tropical backdrop, and you’ll see playing card suits, cutlasses, parrots and an assortment of detailed pirate symbols.

The straightforward control panel features Plus and Minus tabs that you click to select a wager level from 0.10 to 50.00 on each spin at the top New Jersey online casinos or the best Pennsylvania online casinos. A Win Booster option increases stakes by 1.5x, to a range of 0.15 to 75.00, but also improves the potential payouts in a respins bonus round.

In the base games, you win by matching 3 or more identical symbols across any of the 20 paylines from the left. To see what each pays out, take a look at the paytable via the 3 small lines on the controls, followed by the ‘I’ tab. The low value card suits return up to 4x your stake, while the lady pirate is worth the most, at up to 50x. A treasure chest scatter symbol pays in any places and is valued at up to 100x.

Control options include automatic spins, and fast-play, and the choice of playing on a PC or mobile.

Free Spins & Other Adventures of Doubloon Island Slot Features

The female pirate captain covers 1, 2, or 3 rows, and she’s a wild symbol who can substitute if needed to complete a win.

Once you collect wins from 3, 4 or 5 treasure chest symbols, you get to enjoy 10, 15, or 20 free spins. It’s easy to land plenty of high-paying combinations during this round, as the lower value card suit symbols don’t appear. More scatter treasure chest symbols will retrigger the free games.

The Adventures of Doubloon Island online slot use the HyperHold respin mechanism found in other Microgaming slots. You trigger the feature by collecting between 6 and 14 HyperHold gold coins, or golden skulls, and it starts off with 3 respins, with the triggering symbols locked in place. Only HyperHold symbols and blank spaces appear, with any new coins or skulls also locking in place, while resetting the respin counter back to 3.

The respins continue until no symbols appear for 3 consecutive games, or you see them fill all 15 positions. Each Hyperhold symbol then pays out between 1x and 50x your total wager, (or up to 100x with the Win Booster), or any of the Mini, Minor, Major, or Mega jackpots. The Mega is worth 2,000x your wager, or 3,333x with the Win Booster activated.
