Brilliant Diamonds: Hold & Win Slot Review
Brilliant Diamonds: Hold & Win launched in February 2022 from iSoftBet, a developer known for straightforward mechanical design. The game presents a luxury wealth theme centred on prestigious symbols like yachts, planes, and diamonds. It’s built on established Hold & Win mechanics rather than groundbreaking features, positioning it firmly for players who appreciate traditional respins gameplay over innovative experimentation.
Base Game & Features
Brilliant Diamonds operates on a 5 reel, 3 row grid with 25 paylines. The game employs a straightforward symbol set featuring high-value luxury items (watches, cars, aeroplanes, champagne) alongside standard card symbols. Base gameplay is characterised by moderate pace with intermittent excitement during modifier activation.
Stacked Wilds
Wild symbols land fully stacked across all five reels, substituting for all regular symbols except the triggering Diamond symbols. Whilst stacked wilds are now commonplace in slot design, they function effectively here to boost win frequency during base spins. Multiple stacked wilds in a single spin can generate competitive payouts, though the feature requires at least three wilds on screen to deliver genuine excitement.
Diamond Modifiers
A randomly triggered modifier can activate during base game, with diamonds raining across the reels. This feature either awards larger wins directly or triggers the Hold & Win respins mechanic. The Diamond Modifier provides occasional engagement boosts, though it activates infrequently enough that base game pacing can feel quite standard between triggers.

Hold & Win Respins & Jackpot Features
The primary bonus attraction centres on Hold & Win respins triggered when landing five or more Diamond symbols (any combination of Platinum or Gold tier). Upon trigger, winning Diamond symbols lock in place whilst the remaining positions respin up to three times. Additional Diamond symbols that land reset the respin counter back to three, continuing until respins exhaust or all positions fill.
Respins feature multiplier awards ranging from modest values to a 1000x Grand Jackpot for the highest tier prize. The feature triggers roughly every 116 spins on average, making it a reasonably regular occurrence within sessions. Win potential during respins reaches 5,440x total stake when optimal multiplier stacking occurs, though the achievability relies heavily on symbol placement rather than guaranteed payouts.
Bonus Buy & Ante Bet
Players can purchase direct access to the Hold & Win respins feature for 50x their total bet. This option elevates the RTP from 96% to 96.9%, offering marginal value improvement. Bonus Buy remains unavailable to UK players due to regulatory restrictions from the Gambling Commission.

Our Honest Verdict
Brilliant Diamonds delivers solid mathematical specifications with 96% base RTP and 5,440x maximum win potential across medium volatility gameplay. However, the overall package feels quite traditional. The luxury wealth theme remains overused within the slot market, whilst Hold & Win mechanics themselves lack the sophistication of newer genre releases. Base game pacing sits squarely in the ho-hum territory between feature triggers, with the Diamond Modifier providing only occasional relief.
The game will suit players seeking straightforward respins mechanics and balanced volatility without requiring feature variety or thematic originality. Hold & Win enthusiasts with specific mechanical preferences should find reasonable value, though even genre specialists may find limited excitement compared to more innovative releases. Casual players preferring uncomplicated mechanics will appreciate the accessible 50x bonus buy and solid RTP, whilst innovation-focused players will likely look elsewhere for creative engagement.
Overall Rating: 3.5/5 – A competent mid-tier slot delivering expected mechanics without distinction. Suitable for Hold & Win fans and traditional players seeking medium volatility balance.
