Gems Bonanza at The Phone Casino

I deal in gems all of the time. Fruit gems that is.

The Gems Bonanza slot is a super volatile jewel-themed game from Pragmatic Play. The action takes place on an 8x8 reel grid with winning combinations formed by landing clusters of 5 or more matching symbols. Special coloured markings can appear behind symbols which can in turn deliver an assortment of modifiers. These include transforming wilds, 2x2 symbol blocks, a whole grid clearance, colossal symbols or up to 15 added wilds. 

With a mysterious pyramid building in the background, there’s a statue that fires off the modifiers when they strike. The bright visuals here are sharp and clear. That’s important in a slot that has so many moving parts. There’s a panpipe-heavy backing track playing in the background. 

On the reels are 7 brightly coloured gems. The most rewarding symbol  is the red jewel. This pays 1,000 x stake if you land a cluster of 25 or more matching symbols. There’s also a wild. This replaces all symbols when it appears in the Wild Gem and Lucky Wild modifiers. 

You can play Gems Bonanza on all devices. Despite the 8x8 game grid being much larger than a standard slot, the crystal-clear imagery is very easy on the eye. The Gems Bonanza mobile slot works very nicely indeed.

Gems Bonanza is based around an innovative multi-tiered progressive bonus with some serious potential thanks to its increasing multipliers. The action will just keep on cascading in this exciting slot game as the gems explode to make way for more potential winning combinations. 

Tumble Feature 

Slot fans will be familiar with this tumbling way of forming wins. When you land a winning combination on the grid, the symbols involved disintegrate allowing the remaining gems to drop down into the empty spaces. This process repeats until there are no new winning clusters formed and it’s time for the next spin. 


Another great feature of the base game is the random modifiers which can significantly boost your wins. Coloured marks will appear randomly behind the symbols on the grid during normal play. If you land a win on top of one of these then it triggers one of 5 modifiers based on the colour of the mark. Trigger more than one at once and they’ll appear in the following order: 

Nuclear (Blue) – clears all the existing symbols from the game grid and drops in an entirely fresh batch, working like a free spins feature in effect. 
Wild Gem (Pink) – converts one random symbol type on the grid into wilds. 
Squares (Golden Brown) – adds in some 2×2 size symbols at random positions on the grid. 
Colossal (Red) – like Squares but symbols up to 5×5 in size randomly appear on the grid. 
Lucky Wilds (Green) – anywhere between 5 and 15 wilds appear in random positions on the grid. 

Gold Fever Progressive 

As symbols cascade down and winning combinations are formed, each exploding group of symbols register on the Gold Fever meter to the right of the playing grid. If you collect 114 winning symbols or more in a row, the meter will be full, and the Gold Fever Progressive feature is triggered. If you get no more winning combination before the feature is triggered then the meter resets. 

Once triggered, you’ll progress through the 5 levels of Modifiers in the order mentioned above starting with a 2x multiplier as long as the winning combinations keep landing on the grid. If the Gold Fever meter is filled up again, then you’ll move up to the next tier of the Gold Fever Progressive with a higher multiplier. There are 5 tiers in total with the top one giving a 10x multiplier. 

If you’ve used up all 5 modifiers in a tier but haven’t collected enough winning symbols to progress to the next one, then the feature ends. 

Gems Bonanza Jackpot 

Although the key feature of the game is called the Gold Fever Progressive, it’s not technically a progressive jackpot. But have no fear, there’s still a potential max win of 10,000x your stake to hunt down in this thrilling slot.
