Head to the wilds of Asia in Big 5 Jungle Jackpot, a 5 reel, 25 payline slot from Stake Logic. This wild animal-themed adventure comes with a bonus round that awards up to 30 free spins complete with a lock and spin bonus which can create some big winning clusters. Fill the reels with matching animal symbols and you can win 1 of 5 fixed jackpot prizes. Start your quest, on all devices, from between 25p and £50 per spin.

A lost jungle civilisation is the setting for Big 5 Jungle Jackpot – set against a vegetation-filled backdrop and flanked by a pair of ruined statues, the reels include stone style A to 10 playing cards alongside snakes, crocodiles, orangutans and elephants. The best payer is the tiger which awards 12 times your stake if you land 5 on a payline. The eye of the tiger is the game’s wild – it replaces everything apart from the Bonus symbol and can land anywhere on the middle 3 reels.

If you manage to fill all the reels with the same animal symbol or wild, you’ll win a special jackpot prize. The figures for each animal can be seen on the special meters above the reels. The tiger is the most lucrative giving you a whopping 1,250 times your stake!

The head of the statue is the Bonus symbol – it can land on reels 2, 3 and 4 only. Land at least 4 of these on the same spin and you’ll trigger the Free Spins feature. The more Bonus symbols that land, the more free spins are awarded – 4, 5, 6, 7, 8 or 9 bonus symbols will give you 10, 12, 15, 20, 25 or 30 free spins respectively.

Land a full stack of an animal symbol on reel 1 during the feature and you’ll trigger the Lock and Spin Bonus feature – the original stack is locked in place and a respin is awarded. If any matching animal or wild symbols join the cluster, they lock too and a further respin follows. The process is repeated until there’s a spin where no new matching symbols land. A final payout is then made with all the matching symbols in position.

Individually, all of the images are nicely done. With so many similar colours on show it can feel a little cluttered though. The gameplay is solid enough too. The Lock and Spin Bonus feature can deliver some impressive results within the free spins round.

The jungle is a popular setting for slot developers. This outing doesn’t offer much in the way of innovation but does deliver some potentially volatile action, especially in the bonus round. If you like the wild theme, Big 5 Jungle Jackpot is well worth exploring – I also suggest trying Playtech’s Jungle Giants which is highly volatile.
