Introduction
If you have played Kingdom Gems, you will know exactly what to expect from FBM Gaming demo slots. This is another well-balanced game from this developer. A wild symbol appears in the base game, replacing every symbol except the scatter. This symbol unlocks a number of free spins played out with a twist - this time, all the low paying royals are removed from the reels.
The slick interface makes it easy to access the paytable. You will find nine symbols, including the jack to ace royals and the two special symbols.
The crystal icons and royals can combine anywhere on adjacent reels for up to 243 ways to win. Green crystal wilds can complete new wins across the reels.
If you are a mobile player, this slot has been fully optimised for all devices and the attractive graphics look good in HD. Playable from just 0.30 coins per spin, there are two versions of this slot. A few free play spins are a good way to get to know a new game.
Theme, graphics & soundtrack
Unlike Kingdom Gems, which had a beautifully realised Chinese theme, this follow-up takes place deep underground where precious gems are mined.
In contrast to the earlier game, the visuals are kept pared-back and mysterious. We are deep in a diamond mine where coloured crystals glow in the dark and can glimpse railway tracks that lead off into the dark.
Underpinning this slot is a brilliant ambient soundtrack that captures just the right mix of wonder and unease.

RTP & volatility
FBM slots share a cookie-cutter template that extends to their variance and RTP. This is another medium volatility slot with 96 per cent RTP that should appeal to most players.
How to play Kingdom Gems Diamond
Before you play, set a session budget that lets you enjoy your game responsibly.
FBM slots have a slick and player-friendly set of game controls centred around the spin button:
1. Use the spade to the left of the spin button to access these game settings:
- Game history
- How to play
- Paytable info
- Turbo spins
2. Click the autospins symbol to the right of the spin button to play between 50 and 300 games.
3. The bet is pre-set at 30, so adjust the level and denomination to arrive at a stake you are happy with.
4. Press the spin button to launch Kingdom Gems Diamond.
Min & max bets + top wins
There is a fixed bet of 30 to cover all 243 ways. This is modified by applying a bet level between 1 - 20 and a modifier between 0.01 and 0.25.
This means a minimum to maximum spread of 0.30 to 150.00 coins per spin, which should cover most styles of play.
The top win in the base game is 300x your stake; however, the potential of the free spins can push that higher.
Even with medium volatility, the scatter symbols are really tricky to land. This makes it difficult to realise this slot’s full potential.
Five of a kind are the highest wins in the base game and pay out in multipliers:
- Amber crystal pays 300x
- Green crystal pays 200x
- Egg-shaped crystal pays 200x
- Pink crystal pays 150x
- Blue crystal pays 150x
- King and ace pay 60x
- Jack and queen pay 40x
Bonus features
Like all BFM slots, this game relies on the balance between the wild in the base game, which can complete winning combos over multiple ways, and the free spins feature:
Wild
Look out for the green cube crystal to score base game wins.
Scatter symbol
The exploded diamond scatter triggers the free spins round bonus.
- 3 scatters unlock 8 free spins
- 4 scatters unlock 10 free spins
- 5 scatters unlock 12 free spins
Free spins feature
During the free spins feature, the lower value jack, queen, king and ace symbols are removed from the reels.
Land three, four or five more scatter symbols to unlock 8, 10 or 12 additional free spins.
Overall review: our verdict
Kingdom Gems Diamond is another solid effort from FBM with identical gameplay to Kingdom Gems. We like the 243 ways mechanism and the fact that the symbol values remain high, which is unusual for a scatter pays slot.
The wild is by far the most valuable symbol here, as the free spins are incredibly difficult to land. If you do land this, it will be like seeing the light at the end of the tunnel.
Having established a decent baseline, we would love to see FBM really push the boundaries in future.
For more wild action, try the Cash of Kingdoms slot with its invading wilds and wild reels in the free spins.
