About This Slot

In a richly illustrated and lush jungle setting, NetEnt have created this new animal-themed slot that works as an upgrade to their Gorilla Kingdom slot. Utilising one of the most fearsome kings of the jungle as its top paying icon, Silverback Gold is a game which centres around symbol upgrades in the bonus round to enhance the pay table and push the win potential up significantly. Anyone who has got lucky in Pink Elephants 1 and 2 from Thunderkick will know what we are talking about here.

As well as its impressive maths model and huge jackpot, Silverback Gold is also notable for its beautiful design and depiction of forest life. The roll call of creatures on the reels are particularly well drawn and the dense backdrop of thick plants and trees tinged with greens and yellow beams of sunlight are inviting.

In terms of mechanics, Silverback Gold is a 5-reel slot with 4 rows of symbols and 1,024 active paylines in play at all times. Fans of the original Gorilla Kingdom fro NetEnt will see that it all looks largely similar, though the provider has ramped up the volatility level and added a new base game feature.

RTP, Variance and Top Payout

The RTP of Sliverback Gold is 96.1%, which is about bang-on average in the online slot world. The volatility level is high, pushed up noticeably from the medium level of the prequel, Gorilla Kingdom, so this offers more risk but higher potential rewards. The minimum bet is 10p, keeping it playable for everyone. The maximum payout of 45,126x stake is impressive and can be achieved with the help of wilds, multipliers wilds, free spins and symbol upgrades in the bonus round.

Symbols and Graphics

The symbols in Silverback Gold include the gorilla – our magnificent silverback protagonist – the leopard, the snake, the bird and the crocodile. Other symbols here are the high cards from 9 through to Ace, which award the lower payouts in the game.

The best-paying symbol is the gorilla, which awards a payout when only 2 matches appear on the reels, giving 4x or 8x stake for 5 of a kind, depending on whether you land the regular or the golden version of this symbol.The other animals pay from 2.5x to 3x stake for 5 of a kind, while the high cards award from 1x to 1.5x stake for 5 matches.

You’ll also find Wild Symbols, which can substitute for all other symbols, except the Scatter, to create more winning combinations. These Wild Symbols can also turn into Multiplier Wilds during the Free Spins round.

What We Don't Like

Gameplay and Features

The best action in Silverback Gold happens in the bonus round where multiplier wilds come into play and building a store of tokens helps to upgrade symbols, but before then a random base game feature can enhance your payouts considerably.

Silverback Attack  

This scary sounding bonus feature can trigger at any time during the game, whether you’re playing in the main game or the Free Spins round. When the silverback attack feature triggers, 6 to 12 additional high-paying Silverback symbols appear on the reels to boost your chances of hitting a big win.

Free Spins Round

Landing 3 or more Scatters activates the Free Spins round with 10, 15 or 20 spins available. Before this starts, you play a quick bonus game of 3 Free Spins where the triggering Scatters are locked into position. Tokens will land on the reels with a value attached. This bonus round ends when the token value reaches 300 or the spins run out.

The Free Spins start after the this short bonus game. The tokens collected are added to a Collect Meter. More tokens appear on the silverback symbols during free spins and as you collect the required number of tokens so symbols from the paytable are upgraded to the silverback symbol.

Symbol Upgrades – How It Works

During the free spins round, the symbol upgrades to Silverback level occur as follows:

30 tokens upgrades crocodiles, 60 tokens upgrades leopards, 120 tokens upgrades snakes, 200 tokens upgrades birds and 300 tokens upgrades regular silverbacks to golden silverbacks. Golden Silverbacks only appear in the free spins round.

And there’s more …

During Free Spins, Wilds have a 2x or 3x Multipliers attached. If more than one Multiplier Wild appears, the values of each are added together. At the same time, each additional Scatter to land on the reels awards another Free Spin.

Feature Buy – Not Available in the UK

If you fancy bypassing the main game, you can buy your way into the Free Spins round for a cost of 100x stake.

Our Verdict

Silverback Gold is an atmospheric and immersive slot that really takes players straight into the depths of the jungle. Those who have played the original NetEnt game will find the visuals very similar to Gorilla Kingdom, but once you get spinning the differences become apparent with much higher volatility replacing the more relaxed style of the previous game.

The best part of this slot is the Free Spins round with the chance to hugely enhance the paytable with those upgrades as well as some tantalising Multiplier Wild Multipliers action. The 45,126x jackpot is an impressive top prize and makes the jungle trek well worth it, even if the sound of a Silverback Attack has you quaking in the undergrowth.

Overall, this is a strong release and fans of Gorilla Kingdom would be advised to check it out. Silverback Gold is released at UK slot sites on 16th December 2021.
