Gem Rush Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + up to 16,807

Stakes Range: 20p to £50 per spin

RTP: 96.03%

Max Win: 10,000 x bet

Gem Rush by Slotmill presents a 5×7 grid and hosts up to 16,807 ways to form winning combinations. Because it works on a Dynamic Ways system, the base game includes up to 15 stone blocks (represented by the rough, brownish boulders); the Dynamite element explodes these, elevating chances to win by expanding the number of active symbols and pathways. Victories trigger the Avalanche feature.

The slot allows bet levels ranging from 20p to £50, adjustable using the on-screen plus and minus controls. Burst Mode and Fast Track add to the pace; they’re available to players outside the UK and provide an autoplay feature and quick access to the game’s exciting bonus rounds.
Gem Rush carries a Return to Player (RTP) rate of 96.1%. Its volatility is high, suggesting that payouts, though less frequent, can be substantial when they occur.

In fact, the game offers a maximum win of up to 10,000 times the bet, which appears most achievable when triggering the Dynamite feature. This clears blocker symbols and expands the active play area. Combine that with the Avalanche feature, where the cumulative effect of successive wins can potentially stack rewards up to the peak payout.

Theme – Gem Hunt with a Side of Dynamite

Theme: Mining

High-Value Symbol: Purple Gem

Compatibility: Mobile, Tablet, Desktop


Gem Rush takes players away on an underground adventure, where every spin delves deeper into a cave packed with shiny paydays. It’s all about the exhilaration of a miner striking it rich.

The graphics are sharp, with a high-definition rendering of symbols that pop against the backdrop of the dark tunnel. It shines with colour while hitting a balance between detail and playfulness. Each icon is illustrated with a charming, cartoon-like style that entertains the eyes, from the deep purples and blues of the rare gems to the golden gleam of the miner’s tools.

I can best describe the audio as merry work song music that perfectly complements the theme. It brings a lively atmosphere without overshadowing the slot mechanics. Also, it doesn’t have the vintage feel of a traditional slot but instead offers a modern take on the mining theme, with each aspect of the game finely tuned to build an atmosphere of excitement and discovery.

Symbol payouts are straightforward to understand:

Gem Rush Mobile


Gem Rush’s graphics remain crisp on both Android and iOS devices, as do the colourful gems and mining-themed icons which scale nicely on smaller screens. It retains all its features and bonuses, with an interface that adapts to touchscreen controls, making it accessible and easy to play on the go. The game’s compatibility with iOS and Android smartphones makes it perfect to play at mobile casino sites.

Gem Rush Bonus Features

Gem Rush is loaded with thrilling bonus features. You’ve got the Avalanche, where winning symbols increase the chances for further payouts. The Gem Crusher is another unique addition—each win drops a new block into this device. Some may contain Power-Ups, which activate on the next Avalanche, such as Multiplier Increases, Wild Conversion, and Gem Conversion.


Whenever I see the ‘Avalanche,’ I sense potential. Winning symbols explode and make space for new ones, giving you consecutive chances at a bigger payday within the same spin.

Gem Crusher

The Gem Crusher is represented as a cartoonish mechanical crusher with a hungry appetite for gems. It’s conveniently located at the bottom right of the screen, ready to munch on any new blocks you win.

Each winning spin feeds the Gem Crusher a new block that could contain Power-Ups, unleashed on subsequent Avalanches:

  • Multiplier increase: Boost your progressive win multiplier up to 5 times.
  • Wild conversion: Transforms selected symbols into wilds.
  • Gem Conversion: Turns a chosen symbol into a gem symbol.
  • Random Wilds: Adds 3 to 7 wilds randomly on the reels.
  • Column Wilds: Changes the symbols on a whole reel into wilds, except for bonus symbols.
  • Dynamite: Blasts away 5 blocker symbols. This means that paying symbols will drop in their place, therefore increasing the active pay lines.
  • Extra Spin: Grants one bonus free spin.

Free Spins


The golden nuggets with the word ‘BONUS’ are Gem Rush’s bonus symbols. Landing three or more will launch you into a bonus round, and the more you get, the more free spins you’ll bag.

Number of Bonus Symbols > Free Spins Awarded

3 > 5

4 > 7

5 > 10

The game unlocks the entire reel set during this round, making all the 16,807 betways available.

Good to know: Throughout these spins, neither the progressive win multiplier nor the progression of the Gem Crusher feature reset.

Fast Track (Not available in the UK)

When you select the Fast Track button, four immediate gameplay options appear:

  • Bonus+ | Free Spins with a x10 win multiplier: This costs 400 times your selected bet and guarantees a game round that triggers Free Spins with an amplified win multiplier (RTP 92.66%).
  • Bonus | Free Spins: For 100 times your selected bet, you can directly enter a Free Spins round (RTP 92.74%).
  • Expand+ | Full expansion with a x3 win multiplier: This option costs 40 times the bet, and it secures a game round with expanded win ways and a tripled win multiplier (RTP 92.60%).
  • Expand | Full expansion: With 10 times your bet, you can guarantee a game round that fully expands the reel grid.

Burst Mode (Not available in the UK)

Burst Mode is an exclusive Slotmill autoplay function that bypasses the usual reel animations and visual flair in the standard gameplay mode. Despite the accelerated pace, it works on the exact Random Number Generator (RNG) system and includes all the same features.

To initiate Burst Mode, click the ‘B’ icon on the right side of the reels. At that point, the interface changes to a setup screen where you can fine-tune your autoplay experience by:

  • Setting bet size: Choose the amount to wager on each spin.
  • Setting the number of spins: Select how many spins to execute, with options ranging from ten to infinite series.
  • Choosing to stop if you win a bonus round: Check this option to pause Burst Mode and play the bonus round manually if it’s triggered during autoplay.

Once Burst Mode starts, the focus is solely on the outcomes. It speeds through spins and presents only the essential information, like your total win, the biggest win, bonus rounds triggered, and the total number of rounds played.
