Gems Bonanza Game Background

The Gems Bonanza UK online casino game was released by Pragmatic Play on 29th October 2020. It features a larger than usual 8x8 reel set-up. That’s a whopping 64 symbols on-screen on any given spin. Additionally, the slot comes with 20 paylines and a max. Win 10x multiplier. On top of that, the base game is fun to play on its own, while the numerous bonus features ramp up the thrills and excitement. Adding to the appeal is the Gems Bonanza slot’s Aztec-themed presentation, with its elaborate graphics, symbol designs, ambient sound effects and music.

Gems Bonanza Game Design

Pragmatic Play has created something exceptional with this slot. If the game has a primary colour, it’s brown, which is not what you might expect from a slot called Gems Bonanza. The reason that brown dominates is the grid in which the reels are housed, which is crafted to look like an ancient scroll or parchment. The symbols on the reels - representing all sorts of gems and jewels - are a riot of colour, which contrasts nicely against the brown of the grid. Behind the reels, the graphics take on an isometric point of view. To the left is what appears to be the entrance to an ancient temple, while beyond that are craggy canyons and mountain regions. To the right is a view of the inner temple; a furnace dripping molten gold can be seen, alongside a giant Aztec structure with a face on it. Complementing this is ambient sounds of singing birds together with an ominous, mysterious score that’s punctuated with drum beats when the reels are in play. All in all, the Gems Bonanza slot has a wonderfully atmospheric presentation that’s sure to please.

Gem Bonanza Mobile

The Gems Bonanza slot game is available across - and offers a high-quality experience on - a wide range of devices, including desktop PC, Android and Apple. The only requirement is a stable internet connection so you can load the game up, here at Lottomart Games.

Gem Bonanza Symbols

The symbols are colourful, elaborately detailed and fit the theme of the slot to a tee.

Interestingly - and rather uniquely - there are no lower paying card suit symbols in this slot. What you have are 7 unique gemstones, each a different colour and design. These have a payout of between 50x to 1000x the stake for 25 or more on the reels. Just a general note as well. All these symbols pay in connected horizontal or vertical blocks of 5, which is why the minimum payout is for 5-of-a-kind of each symbol on the reels.

Next up is the game’s Wild symbol, represented by an elaborate green jewel set into an ornate gold casing. The Wild symbol appears only as part of the Wild Gem and Lucky Wilds features, so it only substitutes for other paying symbols during these 2 bonus rounds. Speaking of features, let’s take a look at them now. The symbols in this game are similar to the crystal-crazy Starburst slot.

Gems Bonanza Bonus Features

Tumble Feature

This function is available from the outset as soon as you land a winning combination on the reels. The winning symbols disappear and are replaced with other symbols dropping from above. If those symbols form winning combinations, then the tumble feature continues for as long as there are winning symbols forming winning combinations.

Spin Feature

During the base game, special coloured markings can appear on the board behind the normal symbols. Whenever a win occurs on top of a marked spot, 1 of 5 modifiers are triggered depending on the colour of the markings. Let’s take a look:

  • Nuclear (Blue Mark) = the screen is cleared of all symbols and new symbols appear on the screen
  • Wild Gem (Pink Mark) = all instances of 1 random symbol present on the screen are transformed into Wilds.
  • Squares (Brown Mark) = random 2x2 blocks of the same symbol are added in random positions on the screen.
  • Colossal Symbols (Red Mark) = random 3x3, 4x4 or 5x5 blocks of the same symbol are added in random positions on the screen.
  • Lucky Wilds (Green Mark) = 5 - 15 Wild symbols are added to the reels in random positions.

If multiple features are won on the same spin, the modifiers play in the following, fixed order – Nuclear, Wild Gem, Squares, Colossal Symbol, and Lucky Wilds.

Gold Fever

At every spin, the number of winning symbols that exploded as a result of a tumble is counted, filling the Gold Fever meter located to the right of the reels (the large Aztec statue with the face on it - a feature shared with similarly-themed Aztec Gems Deluxe). The meter resets back to 0 if no new winning symbols explode as a result of a tumble. However, collect 114 winning symbols and the Gold Fever meter fills up completely. The feature then begins when the latest tumble finishes. The Gold Fever feature starts at level 1 and progresses through a total of 5. Here’s a complete breakdown:

  • Level 1 = collect 114 symbols. Played with a 2x multiplier
  • Level 2 = collect 116 symbols. Played with a 4x multiplier
  • Level 3 = collect 120 symbols. Played with a 6x multiplier
  • Level 4 = collect 125 symbols. Played with a 8x multiplier
  • Level 4 = collect 132 symbols. Played with a 10x multiplier

Collecting the prerequisite number of symbols is required to progress through each of the levels. The feature ends when not enough winning symbols have been collected to progress through to the next level.


The Gems Bonanza game is another excellent entry by Pragmatic Play. The base game is fun to play on its own, and the excitement levels skyrocket with the slot game’s numerous bonus rounds and extra features, which offer greater chances of potentially landing a big payout. This is complemented by the game’s excellent and ultra-detailed Aztec-themed looking visual and aural presentation, which is both immersive and a lot of fun to engage with. If you enjoy this online slot and love games centred around similar themes, we recommend the Aztec Bonanza slot game, also from Pragmatic Play.
