Diamond Wild Slot Review
TLDR: Diamond Wild is IGT's classic-themed slot running on a five-reel, three-row grid with 20 fixed paylines and medium to high volatility. The RTP is 92.06%, significantly below the UK industry benchmark of 96%, and the maximum win is 250,000x stake. The symbol set is traditional — Cherries, Bells, Single/Double/Triple Bars, Red 7, Dollar Sign — with the Diamond symbol paying as a scatter (up to 2,500x bet for nine Diamonds anywhere on the reels) and the Wild substituting for all except the Bonus and Diamond. Three or more Bonus symbols trigger 8 Free Spins with a 2x multiplier on all wins; Diamond wins are not doubled during Free Spins. Diamond Wild suits players who want a straightforward classic slot with a scatter pay mechanic; the 92.06% RTP is a four-point shortfall against benchmark that makes this difficult to recommend ahead of higher-RTP alternatives. Gambling Zone rates it 5.5/10. Find the best regulated UK sites to play Diamond Wild below. In this Diamond Wild slot review, we cover IGT's five-reel classic slot — the Diamond scatter pay, the 8-spin Free Spins bonus with 2x multiplier, the Wild's substitution rules, and the 92.06% RTP that defines its value proposition.

Diamond Wild RTP and Wagering
Diamond Wild plays on a five-reel, three-row grid with 20 fixed paylines. Wins form from left to right across adjacent reels. Stakes run from £0.20 to £70 per spin — a broader range than many UK slot games, which makes it accessible at low stakes and viable at mid-stake levels.
The RTP of 92.06% is approximately four points below the UK industry benchmark of 96%. That is not a small gap. A four-point difference in theoretical return rate compounds significantly over any sustained session. IGT offers higher-RTP titles across its catalogue; players who factor return rate into their game selection should compare Diamond Wild against those alternatives before committing to extended play.
Volatility is medium to high. The Diamond scatter pay (up to 2,500x bet for nine Diamonds on the reels) and the 2x multiplier during Free Spins are the two routes to above-average session outcomes; neither is frequent. The maximum win of 250,000x stake is the ceiling, requiring an exceptional confluence of conditions.

Diamond Wild Symbols and Audio and Video Design
Diamond Wild uses a classic slot symbol set — Bars, Cherries, Bells, Red 7, Dollar Sign — presented in IGT's clean, dark-background production style. The Diamond motif appears on the Wild symbol and the standalone Diamond scatter rather than across the full reel set. Production is professional and legible; win animations are clear without being elaborate. This is a functional visual design built around instant symbol recognition rather than immersive theming.
The audio track is neutral — a light background score that does not distract from extended play.
Pay values are per-payline win multipliers. All 20 paylines are active on every spin.

Diamond Wild Mobile Features
Diamond Wild is built on HTML5 and runs directly in mobile browsers across desktop, mobile, and tablet without requiring a download. The 20-payline five-reel layout is a standard configuration that scales cleanly on smaller screens. IGT's mobile interface for gem-themed slots is established and consistent — bet controls, payline display, and win animations are all readable at mobile resolution.
Diamond Wild Bonus Features
Diamond Wild has two bonus mechanics: the Diamond scatter pay (active in the base game and all times) and the Free Spins feature triggered by the Bonus symbol.
Diamond Scatter Pay
The Diamond symbol pays based on the total number of Diamond symbols visible anywhere on the reels, regardless of payline position. The pay scale runs from 3 Diamonds (1x bet) up to 9 Diamonds (2,500x bet). Diamond wins are independent of the payline mechanic and are not doubled during Free Spins.
Free Spins
Landing three or more Bonus symbols anywhere on the reels triggers 8 Free Spins. All wins during Free Spins are multiplied by 2x, with one exception: Diamond scatter wins are not doubled during the feature and pay at their standard rate. The Wild symbol remains active during Free Spins, substituting for all symbols except the Bonus and the Diamond.
Diamond Wild Final Thoughts
IGT knows how to build a classic slot. The symbol set is immediately legible — Bars, Bells, Cherries, Sevens — and the Diamond scatter adds a second pay dimension that runs alongside the payline mechanic without complicating it. The Bonus symbol triggering 8 Free Spins with a 2x multiplier is a clean, predictable structure. Nothing here is hard to follow.
The problem is the 92.06% RTP. I cannot look past it. A four-point gap below the 96% benchmark is not a negligible difference — it is the kind of shortfall that should appear in the first line of any recommendation, not buried in a footnote. The medium-to-high volatility means sessions will swing — which makes the 92.06% RTP a more pronounced cost, not a smaller one. If IGT brings out a version of this at 95% or above, the score changes. At 92.06%, the RTP is the review.
Rating: 5.5
