Venture deep into the rainforest in Dark Jungle, a 5 reel, 40 payline slot from Red Tiger Gaming and Cayetano Gaming. It comes with stacked wilds, a gorilla who can award an instant win of up to 50 times your total stake as well as a free spins round with streak re-spins. Play on all devices from between 40p and £40 per spin.

The action here takes place against a dense, jungle backdrop. On the reels you’ll see lower value A to 9 symbols plus higher value animals. They include a toucan, a snake and a monkey. The best of the standard symbols is the black panther which awards 10 times your stake if you land 5 on 1 of the 40 paylines.

Helping to create the winners is the wild tiger which spins in a stacked formation. This substitutes for all other symbols and also offers payouts of 1, 5 or 12.5 times your stake per payline. Keep a special look out for the gorilla symbol. When this lands on reel 3, it awards an instant prize of up to 50 times your total stake.

The main feature is the Free Spins feature which is triggered by landing scatters on reels 2, 3 and 4 on the same spin. You’ll then receive 9 free spins. It’s here that things can get very interesting. Land a winner during the free spins and the winning symbols are locked in place and a re-spin is awarded.

Known as the Progressive Lock & Respin feature, these keep on coming as long as a new matching symbol joins the winning combination. The payout is then multiplied by the number of re-spins you managed to land. Re-triggers are possible here too if you land 3 scatters on the same free spin.

Dark Jungle is a simple game. The colourful visuals are pretty basic but do the job. You’ll hear the noises of the jungle as you spin which gives the game a nice atmosphere. The gameplay is also pretty straightforward. We found the Free Spins feature quite tricky to land.

It has the potential to be a cracker when it does arrive though. Get on a roll with the streak re-spins and some big results are possible. We’d put the variance in the medium to high range. This trek is an entertaining one, especially if you manage to land the feature. Get lucky with those streak re-spins and Dark Jungle can deliver some cracking action. If you like the theme, Jungle Giants by Playtech is one to try.
