Gems Bonanza Slot Review

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. Collect winning symbols in a meter. Reach the threshold and you’ll trigger the Gold Fever Progressive feature where all the colour modifiers play out in turn. Look out too for multipliers which can get payouts racing.

Gems Bonanza Theme – Audio & Design Features – shimmering jewels

Gems Bonanza slot base game

As you’d expect given its name, shimmering jewels dominate the reels in Gems Bonanza. 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 8×8 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.

Bonus Features in Gems Bonanza

In the Gems Bonanza slot, the gameplay is a little unusual. There’s the grid setup and tumbling reels for starters. Coloured markers can in turn can bring a host of modifiers into play. Then there’s the Gold Fever Feature where the modifiers play out in turn. Work through the levels there to activate multipliers. We’ll start with the game grid.

Spin features

On any base game spin, you could see a coloured marking appear behind a symbol. If that symbol becomes part of a winning combination, the coloured marking triggers a modifier. If that creates a winner, a standard tumble then follows. Again, these continue until there’s no new winner. The markings deliver the following extras. It’s possible to land multiple modifiers on the same spin. The modifiers/features play out in sequence.

  • Nuclear feature: this is triggered by the blue marking. All the symbols on the grid are removed and a totally new set of symbols replace them. A new payout consideration is then made.
  • Wild Gem feature: this is triggered by the pink marking. After the round of tumbles is complete, all examples 1 symbol turn into wilds. A new payout calculation then follows.
  • Squares feature: it’s the brown marking that triggers this extra. A 2×2 symbol block is added to a random position on the reels and a new payout calculation is made.
  • Colossal feature: the red mark awards the Colossal modifier. A 3×3, 4×4 or even 5×5 symbol block is added.
  • Lucky Wilds feature: green marks the arrival of the Lucky Wilds. Between 5 and 15 wild symbols are added to the grid. A payout then follows with the wilds in place, followed by a new tumble.

Gold Fever Progressive feature

Gems Bonanza slot Gold Fever Progressive feature

Each time you land a winning cluster from a single set of tumbles, the symbols are added to a meter to the left of the reels. Collect 114 symbols from a single spin and a set of tumbles to trigger the Gold Fever Progressive feature.

You’ll then get a ‘spin’ where all the modifiers play out in succession. Boosting your chances here is a 2x multiplier. Once again, winning symbols are collected in a meter. Collect enough symbols to fill the meter and you’ll advance to the next level where even bigger multipliers are in play:

Level 1 Collect 114 symbols 2x multiplier
Level 2 Collect 116 symbols 4x multiplier
Level 3 Collect 120 symbols 6x multiplier
Level 4 Collect 125 symbols 8x multiplier
Level 5 Collect 130 symbols 10x multiplier

The meter reverts to zero at the start of a new spin. Finally, in some territories, you’ll have the option to buy the Gold Fever Progressive feature for a fee of 100 x your total stake. The Collect numbers are slightly different to standard play but otherwise, the feature is the same.

Gems Bonanza Review Summary – exciting + high win potential cluster pays slot

I was very impressed by what I found in the Gems Bonanza slot. The sound and visuals are terrific, creating loads of atmosphere. The modifiers keep the cluster pays game engine motoring along too.

The action here can really rev up during the Gold Fever Progressive feature, especially if you collect enough symbols to advance through the levels and bring the larger multipliers into play. Be warned though, this is an extremely volatile slot.

The best of the Spin features is the Lucky Wilds feature as landing up to 15 wilds can easily give you 114 or more winning symbols which will bring other levels and their subsequent multipliers into action. The hope is that you get a big multiplier with all the Spin features playing out in sequence.

If you like slots that deliver classy designed, innovative extras and volcanic variance, Gems Bonanza should appeal. Like grid/cluster pays slots? Reactoonz 2 by Play ‘n GO and Jammin’ Jars by Push Gaming are worth investigating.
