Launched on 22 April 2016, the Blue Diamond from slot provider Red Tiger Gaming features a clean, classic theme reminiscent of older fruit machines. We quickly observed how the deep blue background really makes the bright cherries, BARs, and red 7s pop, as if it were intended to do so.
For us, the colour balance was good. Nothing was flashing, and there weren’t overbearing light bursts, which can be an issue when playing a different slot. The spin and transition of the reels are softish with a fair level of modesty, matching the older traditional look of the slot rather than other, more modern productions that tend to aim for thicker stories.
Aesthetically speaking, the Blue Diamond slot game retains the traditional jingle-type pub machine. The tune in the background is relatively light and brief, serving only to provide rhythm without putting any pressure on the player.
The Blue Diamond slot features a single-line payout structure, rewarding players for lining up symbols from left to right on its three reels. Aside from the Wild Respin extra feature, which locks Blue Diamond symbols in place and awards players an additional spin, the game is otherwise similar to a regular fruit machine.
The pay table lists familiar fruit-machine icons:
The Blue Diamond Wild substitutes for other icons and locks when part of a win, triggering the Wild Respin feature. Two Wilds re-trigger another respin, and three pay 888× the stake, the slot’s max win. No separate Scatter exists, keeping the grid focused on direct symbol payouts.
I found the balance between low and high symbols steady, with BARs acting as filler while Wilds and 7s drive genuine payout spikes. The overall reward curve feels fair for a single-payline title, especially considering how the top Wild sequence delivers the strongest payout in the game.

Bonus Features
The single bonus feature in the game, called the Wild Respin, functions more as a respin chain than free spins. After the first Wild lands, the first Wild will lock into place for a respin, and if the second Wild lands, it locks again for a respin. The third respin ends the chain and pays a jackpot multiplier.
Below is the complete pay table showing how each symbol ranks.
| Symbol Combination | Payout Multiplier |
|---|---|
| 3 × Wild Respin | x888 |
| 3 × Red 7s | x88 |
| 3 × Triple BAR | x38 |
| 3 × Double BAR | x28 |
| 3 × Single BAR | x18 |
| Any 3 BARs | x8 |
| 3 × Cherries | x5 |
| 2 × Cherries | x3 |
| 1 × Cherry | x1 |

Next, we’ll cover how to play Blue Diamond, outlining its reel layout, single payline structure, and the key settings that shape every spin.
The Blue Diamond slot machine features a 3×1 grid and a single fixed payline. Bets range from £0.10 to £5 per spin, making it approachable for cautious UK players and still flexible enough for small-stakes strategy tests. The RTP is around 95.12%, and the volatility is high.
The control panel sits directly beneath the reels. Bet levels are adjusted using the plus and minus buttons, and the spin and autospin buttons are conveniently centrally mounted. The Autoplay mode allows for continuous rounds; however, it offers limited setting options, making it a classic slot game.
During my test, the reel spin felt tight and consistent, with no noticeable lag. The autoplay ran easily for set batches, and button responses were immediate. I’d recommend this slot for beginners seeking to learn timing or bankroll pacing on a low-limit game.
We tested the Blue Diamond, focusing on its core Wild Respin feature to gauge trigger rate, payout flow, and overall rhythm.
I triggered the Wild Respin after landing a Blue Diamond on the centre line; it locked in place and awarded a free respin. A second Wild appeared and remained stationary, but the third never showed up. Still, the two Wilds provided a steady payout of around 20 times my stake. Based on the pay table, three Wilds would pay 888×, which explains the tension each time one lands. The absence of free spins keeps Blue Diamond focused and quick, ideal for short sessions with visible payout results.
Blue Diamond from Red Tiger Gaming is one of the few slots that demonstrates that less can still be fulfilling. We see it as a fresh, contemporary version of the one-line fruit machine, with a simple layout, a consistent beat, and a single element that maintains the tension. While its regulated RTP and volatility make it a good option for players who like brief, concentrated sessions, the Wild Respin can turn an ordinary spin into a large reward. Anyone wishing to play Blue Diamond for fun or try it before betting can do so through the UK casino sites we recommend.
