Review

This slot game might just be one of the best slots ever released by this studio. It’s a surprisingly complex affair, and it also gives you a chance to win some truly tremendous payouts! We’ll get to all those important details in due time, of course, and we’ll leave no stone unturned before we give you our final verdict. Let’s start with the game’s playing field, then. It consists of 5 reels, 3 rows and 25 fixed paylines, so it’s rather classic. During free spins, though, you can get access to three such playing fields, which means up to 75 paylines in total!

The theme of this slot is quite intriguing. Essentially, you’re adventurers on an island full of colorful and mysterious animals, some of which were already supposed to be extinct. The production values of the slot are outright amazing, and we love the various symbol designs, which are both colorful and intricate. We highly appreciate this, especially since slots haven’t always been particularly good in terms of presentation. This one is, though, so we simply must praise the designers for their efforts!

Let’s now take a look at the mathematical model of this slot. The game’s volatility is marked as low, but you can win up to 81,885x your bet if you get lucky! The game’s betting range then goes from £0.30 to £90 per spin, which should satisfy pretty much everyone. As for the game’s theoretical RTP, there are two possible values, 94.02% and 95.99%. Avoiding the former is naturally strongly recommended.

Slot Features

The paytable of this slot offers a set of 10 pay symbols, and they all come with nice designs. That applies even to the game’s five low-paying symbols that are all about card ranks from Tens to Aces, while the designs of the game’s high-paying symbols are outright gorgeous. Those show planes, three animals, and female adventurers. Female adventurers pay the most, and two of the high-paying symbols actually pay out even in sets of just two.

In terms of special symbols, there are Wilds and Scatters. Wilds can substitute for other symbols, and they can appear only on the middle three reels. Their full potential is then unlocked during free spins, which you can trigger by finding enough Scatters in view.

Landing 3, 4, or 5 Scatters triggers the Free Spins feature with 8 free spins. The game actually calls them Bonus Respins, though the actual mechanics are closer to free spins than respins. Now – while Scatters can appear anywhere on the board during the base game, they appear only on reels 2 and 4 of the original playing field during free spins. Landing two of them during free spins resets the counter of free spins back to 8, and it also unlocks a new reel set, to a maximum of 3.

Unlocking new reel sets gives you access not only to new reel playing fields, but also to Multiplier Wilds with 2x and 3x win multipliers. These can work together to produce win multipliers as high as 27x, which can lead to some seriously juicy payouts!

Playing with three reel sets is always a lot of fun, too, and you’ll always be on the lookout for those required Scatters. It’s a neat concept that feels great, and it adds another layer to a slot that would otherwise feel a bit run-of-the-mill.

Review Summary

Although this slot won’t revolutionize the slot gaming industry, the slot does feel like they are trying to reinvent themselves, and that’s something that we’re really happy about. It’s an enjoyable package that we’re getting here, and it’s one that we can recommend to all players, as you simply don’t get to play with as many as 3 playing fields at once all that often!
