Adventures of Doubloon Island Tips & Strategy

We enjoyed our outing with Adventures of Doubloon Island. Besides, that the theme gives the player a sense of an escape. If you just want to wind down the clock and have a bit of fun at the same time. The slot won’t disappoint. We didn’t go big and played it with a budget of €200.

We played the slot with real money for 4 sessions only, each session was 25 spins. The hit rate checks out since we received a payout on every 3 to 5 spins. The average winner in the base game is €0.20 to €3.5. We did trigger the HyperHold feature and won €54. In the free spins we received a payout of €26. All within a 100 spins, not bad me hearties!

If you want to give Adventures of Doubloon Island a go without any risk. The free slots version of it is a great start. Note, your free play should match your play for real money. If your average bet is 5 credits keep it the same when you play for free. It gives you a better perspective as to how the game pays at that bet level.



Adventures of Doubloon Island is an entertaining romp ideal for low rollers. The math model is soft and it keeps the wins coming. The bonus rounds offer something different regardless if you play with the Win Booster or not. However, if you’re a jackpot hunter we recommend that you use it.

With the clash of swords, the grog in your stomach and the deck at your feet. There’s nothing more liberating then being a pirate. Triple Edge Studios did a good job and any landlubber will enjoy it!

For a different sort of pirate adventure, check out Relax Gaming’s The Golden Sail slot. It builds on its Big Wheel with many rewards. Those include free spins with a progressive win multiplier. The math model is tighter, but the top jackpot is high at 10,000x. It’s your call – and you can enjoy both games at our top European online casinos!
