The artwork used here is outstanding, with highly realistic images of the various animals bringing a jungle adventure to PCs, iOS, Android, and Windows mobiles in stunning detail. Lower paying symbols are made up of the classic playing card emblems. The backdrop to the 5x4 reel set is a lush forest with a huge mountain in the distance, and the soundtrack includes animal noises to help set the scene.
It’s a 4096 ways to win game, meaning that you need to land 3 or more identical symbols on adjacent reels, on any of the 4 rows, from left to right. The gorilla is a wild symbol and the Silverback: Multiplier Mountain slot lives up to its name with a win multiplier feature during a free spins bonus round. While you can win up to 5400x your bet in the base games, this rises to a huge 25,000x in the free spins at our highest ranked casino sites.
You can wager a minimum of 0.20 on each spin, with the maximum of 10.00 being too low for some players. Like all Microgaming slots, it’s easy to play and the control buttons work perfectly well across desktop and mobile versions of the Silverback: Multiplier Mountain slot machine. Click the image of a Poker chip to select your bet level from the available options.
Other control buttons include the arrow in a circle which activates automatic spins, and if you click the $ symbol, you open up a paytable that lists how much each symbol is worth. The gorilla pays the most, with 7.5x your total bet returned when he’s seen across all 6 reels at once.
As well as providing a dramatic backdrop to the reels, and part of the game title, the mountain has a further purpose. If it appears in any 3, 4, 5, or 6 places at once, it unlocks 10, 15, 20, or 30 free spins respectively.
This is a pretty special round, where any winning spin adds 1 extra free game to the total available at the slot game casinos. On top of this, any more mountain scatter symbols appearing throughout the feature will also extend the free games by 1 spin. Wins also increase a multiplier by 1x, so that by the end of this round you could have enjoyed multiple bonus games, with prizes boosted many times over.
Although wins max out at 5400x in the base games, during the free spins they can increase to a massive 25,000x. However, because you can only stake up to 10.00 per spin, the biggest possible win is 250,000.00, which is less than in many other games.
The Silverback: Multiplier Mountain slot has a high volatility and over the long-term, the payback percentage is 96.22%.

This is a great-looking game which is sure to impress players across desktop and mobile platforms. The 6-reel, 4096 ways to win setup leads to a big grid of 24 symbols in view, which can make them a little harder to see on small screens, but when they look so good, most players won’t have a problem with it.
More serious is the very low maximum stakes of 10.00 per spin, which really limits this slot to low and mid-range players. However, the potential for big win multipliers can still lead to decent, if not huge prizes.
This wildlife-themed game comes to life in the fantastic free spins round, where wins add extra games to the total and increase a win multiplier for the rest of the feature.
If you want a similar game that you can play for higher stakes, try the Gorilla Kingdom online slot from NetEnt, where you can wager up to 350.00 per spin.
