Venture into the jungles of Africa in Diamond Chief, a 5 reel, 100 payline video slot from Aussie developer Ainsworth. The main attraction on offer in this fast-paced game is the free spins feature where extra wilds are added to the reels. You can also boost your winning paylines courtesy of wild multipliers. Play from between £1 and £75 per spin.

The reels in Diamond Chief are set against a rich jungle backdrop – a little unusual they are too featuring 2 reels with 2 rows and 3 reels with the more traditional 5. Accompanying the standard playing card symbols are a selection of nicely drawn wild animals including birds, hippos, gorillas and elephants. They’re joined by a waterfall scene which is the top payer of the standard symbols offering 750 times your line bet if you land 5 in a payline.

The Diamond Chief Logo is the wild – it appears as stacked on reels 3, 4 and 5 in the base game and substitutes for everything apart from the scatter. The diamond is the scatter – land 3, 4 or 5 for a payout of 1, 5 or 50 times your total stakes. You’ll also trigger the Free Games feature and be awarded 10 free spins.

A new wild symbol, the shield, is added to the reels for the feature – this comes in addition to the standard wild. Whenever the shield lands, you’ll be awarded a shield multiplier of 2x or 3x for the next 3 spins if that symbols forms part of a winning combo.

Land more than 1 shield multiplier in a winner and you can combine the multipliers to offer to very impressive boosts (up to 27x!). The diamond scatter only appears on reels 1 and 2 during the feature – land 2 of them and you’ll receive and extra 5 free spins.

The jungle can be a place of danger for the unwary and the same applies here – this a pretty volatile slot. Expect plenty of lean spells when little happens on the winnings front but hope to cash in during the feature where the multipliers can make a real difference.

Diamond Chief is a well-designed slot and the visuals are impressively done. In terms of features, it’s all about the bonus round. Get lucky with the multipliers with your free spins and you’ll find Diamond Chief to be a little gem of a slot. If you like the jungle theme, there’s plenty to choose from fortunately with IGT’s Prowling Panther and NetEnt’s Go Bananas being good options.
