Gems, Bombs & Gold™ Slot RTP, Details & Wager Limits
The Gems, Bombs & Gold™ slot game uses a 5×5 layout and replaces the traditional payline format found in many online slot games with a cluster-pays system. Therefore, to score a win, you need a collection of 5 or more matching symbols connected vertically or horizontally.
Click on the coins icon to open the full bet configuration menu. 21 options are available, and casual players can start from as little as 20p. However, high rollers may find it disappointing that the limit only reaches £25. Still, for those playing from Gems, Bombs & Gold™ casinos in the UK, the maximum bet is capped at £5.
Autoplay is an option, but it won’t be available in the UK. This would let the game spin on its own for 10 to 100 rounds, saving you from clicking each time. The same goes for the Quickspin option.
The Games Global studio Just For The Win has set the Gems, Bombs & Gold™ RTP at 96%, which sits right around the industry average for the best online slots. And with the game’s high volatility, you’re looking at less frequent wins but the potential for bigger payouts when they do land.
Moreover, the Gems, Bombs & Gold™ max win can reach up to 10,187x your bet. That’s a pretty standard figure, and it sits well among what many new slots online are offering. My wins while testing the Gems, Bombs & Gold™ demo have so far gone up to 300x.

Gems, Bombs & Gold™ Theme—Treasure Hunt in Caverns of Crystals, Multipliers, and Riches
Gems, Bombs & Gold™ transported me to a mine carved into rock walls. The setting was quite dim but warmed by the glow of lanterns hanging on both sides of the reel frame. The reels themselves sit on a wooden rig secured with metal clamps and bolts, with purple cables draped around it and down to the blasting box.
The audio struck me as quite tense. More particularly, the backing soundscape involves drum-like thuds with metallic echoes. This gives the impression of picks striking stone somewhere in the background. And as the reels spin and the wins drop in, that steady track gets drowned out by a mix of clinks and chimes.
The paytable starts with the lower-paying symbols, which are carved card royals J to A. From there, the focus shifts to coloured crystals, multiplier wilds, and bonus scatters that carry the features.
Here’s what each pays out at the top online casinos:
| Symbol | Payouts/Info |
|---|---|
 J

5 to 25+ = 0.2x to 6x the stake |
 Q
|
5 to 25+ = 0.2x to 6x the stake |
 K
|
5 to 25+ = 0.3x to 8x the stake |
 A
|

 Green Gem
|
5 to 25+ = 0.5x to 12.5x the stake |
 Blue Gem
|

 Red Gem
|
5 to 25+ = 0.8x to 25x the stake |
 Purple Gem
|
5 to 25+ = 1x to 50x the stake |
 Multiplier Wild

Gems, Bombs & Gold™ Mobile Slot
Everything about Gems, Bombs & Gold™ was fully optimised to fit the screen in portrait mode, with all menu icons placed for easy thumb access. I wouldn’t say the same for the landscape view. Just For The Win could have made better use of the available space.
Even so, the colourful high-quality visuals hold up very well in both orientations. Plus, performance-wise, the gameplay performs very smoothly at mobile casinos. My only recommendation for a less cluttered look would be to hide the toolbar. This way, you get more room for the reels on your device.
Gems, Bombs & Gold™ Bonus Features
Gems, Bombs & Gold™ ties its bonus features closely to the mining theme, with every mechanic built around digging deeper for bigger rewards. From symbols that reshape the grid to sticky values that carry through spins, you’ll see it all.
Multiplier Wild Symbols
Each Multiplier Wild symbol in Gems, Bombs & Gold™ carries a value of x2, x3, x5, or x10 and could land anywhere in both the base game and bonus rounds. Whenever one forms part of a cluster, the win is multiplied by that amount. If more than one appears in the same cluster, the multipliers are added together.
Bomb Symbols
Bomb symbols appear in both the base game and bonus rounds. Upon landing, it’s replaced by a random symbol, but it cannot turn into Bonus, Super Bonus, Multiplier Wild, or another Bomb. Any position directly next to the Bomb, vertically or horizontally, is also replaced by that same random symbol. And if several Bombs land at once, all of them and their adjacent positions transform into the same symbol, which can create very large matching clusters.
Money Symbols
Money symbols can land anywhere during the base game or bonus rounds. Each one is assigned a random value ranging from 0.2x up to 250x the bet. When they form a cluster, all the values are added together and paid as a total prize.
Bonus Spins
You trigger Bonus Spins in Gems, Bombs & Gold™ by landing three Bonus symbols on reels 1, 3, and 5. This awards 10 spins. A Super Bonus symbol on reel 1, combined with two Bonus symbols, results in 10 Super Bonus Spins instead. However, you can only get one type of feature per round, not both at once.
Landing 2 Bonus symbols during these rounds adds 5 extra spins, while 3 Bonus symbols add 10. Also, Multiplier Wilds that appear become sticky for the rest of the round. Cluster wins containing money symbols leave one sticky money symbol on the grid, holding the total combined value of that cluster. If another one forms with a sticky money symbol, the value merges into a new sticky money symbol, and the older ones from that win are removed.
Specifically in the Super Bonus Spins, three additional symbols—either Multiplier Wilds or sticky money symbols—are randomly placed on the reels at the start of the feature. All winnings are automatically collected, and the bet amount is fixed to the last stake placed before triggering the spins.
Diamond Menu (Not Available in UK Online Casinos)
You can buy four feature options at set multiples of your current stake, as follows:
- Bonus Hunt: 1.5x your stake, triples the chance of triggering Bonus Spins or Super Bonus Spins
- Multiplier Wilds + Bomb: 5x your stake, guarantees at least one Multiplier Wild and one Bomb, but cannot trigger Bonus Spins or Super Bonus Spins
- Bonus Spins: 100x your stake, awards 10 Bonus Spins
- Super Bonus Spins: 400x your stake, awards 10 Super Bonus Spins
Gems, Bombs & Gold™ Verdict:
The biggest strength I found in Gems, Bombs & Gold™ was the constant movement created by clusters breaking and reforming. That’s not to mention how the sticky money symbols and Bomb transformations kept the base game from feeling static.
Meanwhile, the Bonus Spins really gave the features room to shine. And despite the high volatility, there’s plenty of incentive to stick with the grind, considering that the max win goes up to 10,187x. That said, the audio loop may feel monotonous over time and make extended sessions feel a bit flat. Still, I highly appreciate the fact that the colourful mining visuals look sharp on both desktop and mobile.
If you’re on the lookout for more mining-themed slots, you can try Peter & Sons’ Dig It!, a high-volatility release with a max payout of 20,000x your stake.
