Go on a trek for hidden jungle gemstones in Jewel Journey, a 5 reel, 25 payline slot from Eyecon. This adventure-themed game comes with a quartet of bonus features including pick’em rounds, a match and win round and free spins with multipliers of up to 12x. Start your quest from between 25p and £12.50 per spin.

Set against a jungle backdrop, the reels include flaming torches and walking boots, swords and hats, green and blue gemstones, tropical flowers and flasks. The most rewarding symbol is the rucksack – land 2, 3, 4 or 5 of these on a payline and you’ll win 3, 20, 100 or 1,000 coins (or 40 times your stake).

The purple gemstone is the wild – it replaces everything apart from the 3 other scatter symbols. When it forms part of a winning line, the payout is doubled. There are 4 different bonus features on offer in Jewel Journey. Each of them is triggered by landing a different scatter. All 4 scatters pay 2, 5, 15 or 100 times your total stake as well as activating a feature:

Match & Win feature – this is triggered by landing 3 or more of the purple gemstone wild/scatter. Pick and try and find matching jewels, each of which awards a cash bonus.

Great Escape feature – 3 tigers trigger this round. Choose 1 of 3 directions to try and escape from the marauding tiger. Prizes of up to 100 times your stake can be won here.

Gem Select feature – find 3 treasure map scatters to activate this round. Pick 1 of 5 coloured gems. If the colour matches the eye of the statue, prizes of up to 60 times your stake can be won. If not, you’ll get a prize worth up to 30 times your stake.

Free Games feature – 3, 4 or 5 professor symbols appearing left to right will get you 6, 9 or 12 free spins. Watch out for the bespectacled prof who appears on every free spin and awards a multiplier of up to 12x. Unfortunately, you cannot retrigger more free spins.

Visually, Jewel Journey is hardly a gem – the 3D graphics look a little cluttered at times and there’s little in the way of a backing track. As usual with Eyecon slots, the features deliver. They’re not the easiest to trigger but offer plenty of potential when they do, especially the free spins round where the multipliers can quickly have an impact.

This is another entertaining slot from Eyecon. It may not be especially easy on the eye but Jewel Journey is a jungle trek well worth making. Saying that, it’s a low variance game so there will be plenty of entertainment on offer – it can be lucrative though with potential wins of up to 960 times your stake on each free spin. If you’re looking for adventure, Jungle Spirit: Call of the Wild by NetEnt will do just the trick.
