Silverback Gold Mobile


Produced using HTML5 technology, Silverback Gold can be enjoyed on mobile devices that use iOS, Android and Windows operating systems. It’s also available on tablet, laptop and PC devices as standard. The 5×4 reel setup works well on whatever device you opt for.

Silverback Gold Bonus Features

Silverback Gold comes with 4 bonus features. With a random Silverback Attack extra which adds up to 20 silverback symbols to the reels, it focuses on the Bonus Game feature where you aim to collect tokens. In the Free Spins feature, this means symbols are upgraded to the highest value symbol for bigger payouts.

Silverback Attack feature

The Silverback Attack feature is randomly activated in the base game and free spins. When triggered, between 6 and 20 high value silverback symbols are added to the reels. This increases your chances of landing a big winning combination.

Bonus Game feature


To play the Bonus Game feature, you need 3 or more scatter symbols anywhere on the reels. Serving as a gateway into the free spins, positions with scatters are locked. The other positions then spin individually.

With 3 spins awarded, only tokens can land on the reels. A token lands and flips to reveal a value as well as resetting the spins tally to 3. This feature continues until you run out of spins, you fill all positions or the collected tokens reaches 300 or more. The value of all tokens are collected with the Free Spins feature beginning.

Free Spins feature

After the Bonus Game feature has taken place, the Free Spins feature commences. 3, 4 or 5 scatters will give you 10, 15 or 20 free spins respectively. Each scatter landing during the feature will give you an additional free spin, with no limits.

The value of all tokens is then added to the Collect Meter. Look out for tokens randomly appearing on Silverback symbols. When you reach certain levels in the Collect Meter, corresponding symbols are upgraded to Silverback symbols:

30 tokens Upgrades Crocodile symbols
60 tokens Upgrades Leopard symbols
120 tokens Upgrades Snake symbols
200 tokens Upgrades Bird symbols
300 tokens Upgrades Silverback symbols

When you collect 300 tokens, Silverback symbols upgrade to Golden Silverback symbols. These are the highest paying symbols and only appear during the Free Spins feature. The Silverback Attack feature can also trigger randomly for up to 20 silverback symbols added.

Finally, there’s a Buy feature. You can buy your way into the Free Spins feature for a fee of 100 x your total stake. This option isn’t available to UK players due to regulation.

Bonus Features

RTP (96.1%)

Max Win (45,126 x)


The Silverback Gold slot has many similarities to Gorilla Kingdom (theme, free spins and symbol upgrades).

However, NetEnt has ramped things up significantly with much higher win potential (45,126 x stake vs 4,096 x stake). There’s also a random feature in the base game which can also apply during the free spins.

Other slots to use symbol transformations include Pink Elephants and Pink Elephants 2 by Thunderkick. NetEnt has superseded these games due to the huge max wins possible.

Overall, Silverback Gold is another slot that looks great, offers something different with big wins available. It follows on from Starburst XXXtreme where an older game has been revamped to offer something bigger and better. Fancy venturing into the jungle with primates? Nolimit City’s Money’s Gold is recommended.

Other slots to use symbol transformations include Pink Elephants and Pink Elephants 2 by Thunderkick. NetEnt has superseded these games due to the huge max wins possible.

  • 45,126 x stake max wins
