Since 2010, Microgaming has stepped back from developing their own video slots, instead relying on smaller, less-well-known studios to do so. One of those software providers is Triple Edge Studios, which developed Adventures of Dubloon Island, a pirate-themed slot that offers free spins, jackpots, and their famous HyperHold mechanic.

With 20 paylines, the slot has five reels and three rows. From as little as 0.10 credits per spin, you can start playing. With a maximum bet of 75 credits per spin, there is plenty of stake variety to choose from.

As Adventures of Dubloon Island is themed around pirates, it is a theme we've seen in a huge number of video slots before, so the game developer was already up against it when they began developing it.

We can't help but feel that Triple Edge Studios have missed the boat somewhat - and while the graphics aren't bad, they don't stand out either. The slot looks like another bog-standard one that doesn't offer anything unique.

The Adventures of Dubloon Island are based on a medium variance math model. Consequently, you can expect to see fairly frequent wins, albeit not always worth a lot.

Adventures of Dubloon Island's RTP is 96.01%, which is fairly "standard" in the modern online gambling industry.

As with its predecessor, Adventures of Dubloon Island offers quite a few bonuses and features, so let's take a look at what these are - and how you can get them.

There's an optional feature in Adventures of Dubloon Island called Win Booster, which you can toggle on/off before each spin begins. Win Booster increases your stake by 1.5X - which is quite a large increase - but by doing so you greatly increase the potential prize value of the HyperHold bonus, which we'll examine below.

When the Win Booster mechanic is activated, all cash prizes during the HyperHold bonus round are increased by 3X, while the jackpots are increased by 2.5X.

Adventures of Dubloon Island's HyperHold bonus round is triggered by landing six or more HyperHold scatter symbols anywhere during the base game. Upon landing a new HyperHold scatter, you will be awarded three re-spins, and your free spin counter will reset to three.

Whenever a symbol lands in view, you'll win between 1X and 50X your total bet. Symbols can also reveal one of the game's four jackpots, worth up to 2,000X your stake - or 3,333X your stake if Win Booster is in play.

Adventures of Dubloon Island also features a free-spins bonus round that is triggered by landing 3, 4, or 5 scatter symbols anywhere in view during the base game. You are only able to land premium symbols during the free-spins because all the game's lower-paying symbols are removed. You can also re-trigger the free-spins bonus round by landing another 3, 4, or 5 scatter symbols anywhere on the screen.

Assassin Moon, another slot from Triple Edge Studio, contains a number of the same bonuses and features as Adventures of Dubloon Island. In Adventures of Dubloon Island, the HyperHold feature - found in both slots - is the main feature, and the four non-progressive jackpots are outlined above the reels. The games, however, differ quite a bit when you look closer.

Adventures of Dubloon Island, for example, offers players a free-spins bonus round - something that Assassin Moon did not - and we believe that this is an excellent addition to the game. Besides offering a greater variety of bonuses and features, it also gives players more chances to win, and there are more bonus features to be discovered.

When it comes to creativity, Adventures of Dubloon Island falls short of what we'd expect in today's iGaming world. Though it doesn't look horrible, there's nothing in the game that really makes it stand out from many other similarly themed games on the market.

Although the gameplay does not seem to be particularly exciting, the bonuses and features offer some (semi) decent win potential, and Adventures of Dubloon Island is likely to do fairly well because it will be released via Microgaming's Quickfire platform.
