A game with awesome potential, Gems Bonanza delivers the expected cluster pays system, something that one could guess simply by looking at its huge layout. You get above average top payouts to look forward to, but this Pragmatic Play slot machine doesn’t end up being as interesting with its story. You’re looking at a simple gems themed design, not one of their best titles if the visuals are important to you.

Gems Bonanza works with 8x8 reels, forming winning clusters of 4 to 25+ symbols, and adding multipliers, wilds, tumbles, colossal symbols, and a lot of other spin modifiers. The bigger target is Gold Fever, a progressive feature with awesome potential. Ultimately, though the slot is the type to have high volatility (5 out of 5 rating), it also has a solid RTP of 96.51%, and a top jackpot that can put back in your pocket up to 10,000x the round’s stake.

Betting and Prizes

You pretend that you’re using 20 active lines for this one, even though the setup actually involves clusters of symbols. You pick up to 10 coins to use on each of those fixed lines, and a denomination which will go as high as $0.50. This gets you bets between $0.20 and $100 per spin, with up to $5 wagered per line.

With the right multipliers applied, a win of up to 10,000x the stake should be possible, but typically a jackpot win will bring you at most 1,000x the stake ($100,000). Having multipliers to help out is going to make a huge difference then, when it comes to the slot’s potential, and you want to get into the Gold Fever feature in order to be able to reach it.

With the volatility set to high, the game is going to be deadly for plenty of its players. Even so, the fairness of the slot is not disputed, as we know that long-term it pays back 96.51% of what’s wagered on it, on average. It’s an above average figure.

Gems Bonanza Slot Features

First of all, a word on how winning clusters are formed. The requirement is for you to have a minimum of 5 matching symbols (wilds can be included there), connected with each other horizontally and or vertically (each of the symbols in that group need to touch at least one other). You get paid based on how many symbols are in the cluster (25+ needed for the highest value) and the type of symbol involved.

Once a cluster is formed, the Tumble mechanic will trigger, and it does this every single time. The cluster’s symbols will disappear, and the rest will fall down to occupy empty positions, re-arranging themselves. New symbols then come from the top, to fill the remaining empty positions.

Another one to mention, though not spectacular, the Wild symbol is going to help out with any cluster formation, provided that it’s next to the symbols involved. It acts as a replacement symbol.

The Spin Features are also present in the game, and they require certain marked positions to have winning symbols on them. Depending on the color of the mark that appears behind a winning symbol, the spin modifiers will vary:

  • Blue Mark: gives you a Nuclear reaction, which removes all symbols and brings others on the reels, for a second chance at a win.
  • Pink Mark: triggers the Wild Gem, a feature which transforms instances of a randomly selected symbol into extra wilds.
  • Brown Mark: brings around Squares, where 2x2 symbols of the same type will show up randomly in view.
  • Red Mark: has a Colossal Symbol added, with a size from 3x3 to 5x5.
  • Green Mark: 5 to 15 extra wilds added at random in view.

As you create your clusters, and you go through tumbles, you also contribute to a meter which is connected to the Gold Fever feature. Once triggered, by filling the meter within a single spin with 114 symbols from winning clusters, you get a free spins feature. You begin at level 1, and you advance by collecting winning symbols. You get a 2x multiplier initially, but it will go up with each new level. For each level, you’re guaranteed to get all spin modifiers to trigger at least once.

You can eventually reach level 5 this way, where a 10x multiplier applies to all wins.

Gold Fever can be triggered directly, if you want to pay for it, 100x the stake required to get it going.

Theme & Design

Gems Bonanza is not the most impressive game area, but the developer seems to want to keep the attention on the features and their potential. What you end up with, is a collection of symbols that show you either the wild gold door, or icons with gemstones colored in red, purple, green, teal, orange, pink and blue. It’s a modern look, but not one to be a big fan of.


Gems Bonanza slot is not going to be a game that everyone will love, its high volatility will take care of that. Nonetheless, once you take into account its potential rewards that can come via the Gold Fever feature, I think you will start to see its appeal. Getting to a feature where you can go from wins of up to 1,000x to a potential jackpot of up to 10,000x, is not going to be easy though, and it’s part of the reason why the slot is so volatile.
