Sticky Diamonds Deluxe
demo and specs

Sticky Diamonds Deluxe is a 5x3, 10-payline video slot from Gamomat with a release date of 13 August 2026. The theme is polished gemstones on a clean grid, aimed squarely at players who prefer the uncluttered visual language of a fruit-machine lineage over the narrative-heavy settings common in modern video slots.

Seven features on a 10-payline diamond grid: more going on under the surface than the clean theme suggests.

The headline specifications are a 96.08% RTP, medium volatility, a 5,000x max win and a bet range of £0.10 to £100 per spin. Seven features are listed in the published spec: Free Games, Retrigger, Sticky Wilds, Stacked Symbols, Bonus Buy, Card Gamble and a Risk Ladder. That set gives the title considerably more mechanical depth than a straightforward classic revival.

Gamomat publishes the RTP, volatility grade, max win, stake range and feature names for this title. What the studio has not published, at the time of writing, are the per-feature mechanics: trigger conditions, the number of free spins the bonus round awards, and the precise rules governing how long the sticky wilds hold their position. This page is updated as those details are released.

The 96.08% RTP sits fractionally above the rough 96% UK market average. In practical terms that means the house retains approximately 3.92p per pound wagered over a very long run of spins. The extra basis points versus a flat 96% game are real, but they accumulate slowly and matter most across hundreds of thousands of spins rather than any single session.

Medium volatility places this title in the middle ground between low-vol games, which return smaller amounts more frequently, and high-vol games, which produce bigger swings and longer cold runs. In practice that means dry patches exist. You should expect stretches of several spins without a meaningful return, but those patches are shorter and less punishing than on a high-vol equivalent with the same RTP.

The max win is 5,000x the stake. At the minimum bet of £0.10, the theoretical ceiling is £500. At the maximum bet of £100, it rises to £500,000. Both figures are single-spin theoretical maximums. The studio has not published how frequently the maximum outcome is achievable, so the only guide to the distribution is the medium-volatility grade itself.

Gamomat has not published a hit-rate figure for Sticky Diamonds Deluxe. Without a stated frequency, the only indicator of how often wins land is the volatility grade: medium implies returns come more regularly than on a high-vol title, but gives no numeric frequency to work with. Where a figure is not in the published spec, this page says so plainly rather than estimating.

Gamomat lists seven features for Sticky Diamonds Deluxe. Here is what each one is and, where the spec provides it, how the mechanic category generally behaves:

• Free Games: a bonus round that runs a set number of spins at no additional cost; in the general category triggered by a scatter combination, though Gamomat has not published the exact trigger count or spin number for this title.
• Retrigger: the ability to re-enter or extend the free-games round by landing the trigger combination again during the bonus; the published spec names the feature but does not state how many additional spins a retrigger awards.
• Sticky Wilds: wild symbols that lock in their grid position for one or more subsequent spins rather than disappearing after a single use; in the general category this extends their substitution effect across multiple spin sequences.
• Stacked Symbols: symbols that appear in a vertical column covering two or more rows of the same reel, raising the chance of several paylines completing at the same time.
• Bonus Buy: an option to purchase direct entry to the bonus round for a set upfront cost; see the note below on GB availability at UKGC casinos.
• Card Gamble: a player-controlled risk mechanic where a portion of a win can be wagered on a card outcome, typically a colour or suit call, to multiply or lose it.
• Risk Ladder: a step-by-step gamble variant where successful picks climb a ladder of increasing payout values; each rung either advances the prize or ends the gamble round.

Gamomat has not published the precise trigger conditions for the Free Games, how many spins the round awards, the exact hold duration for the Sticky Wilds, or the specific rung structure of the Risk Ladder. This page is updated as the studio publishes those details. The Bonus Buy is switched off for GB players at all UKGC-licensed casinos; the UK Gambling Commission banned the feature in September 2019 on the grounds that it allows players to bypass the base game and purchase direct entry to the bonus round, and no UK-facing operator in good standing can offer it.

The 5x3 grid and 10 fixed paylines give Sticky Diamonds Deluxe a compact, traditional layout. Wins form left to right across the fixed lines, and the Stacked Symbols mechanic means a single reel can fill multiple rows with the same symbol, creating the chance of several paylines completing at once. Between features the game plays as a clean spin-and-match title; the diamond theme keeps the symbol set uncluttered and the pay-table easy to read.

The stake range runs from £0.10 to £100 per spin. The lower end suits players who want an extended session on a modest budget; 100 spins at £0.10 costs £10 before any return. At medium volatility, a practical rule of thumb is to hold at least 50 spins' worth of budget at your chosen stake - roughly £5 at the minimum or £5,000 at the maximum - to absorb the dry patches the volatility grade implies without running out early.

Gamomat builds its titles to run in-browser without a separate download, and the mobile experience matches desktop in full. All listed features, including the Card Gamble and Risk Ladder, are available on touchscreen. UKGC rules apply on a phone exactly as on desktop: the same staking limits, the same responsible gambling tools, and Bonus Buy switched off for GB players.

Sticky Diamonds Deluxe sits in the mid-range of diamond-and-gemstone slots with sticky-wild mechanics. Its 96.08% return is competitive without being the field leader, and its 5,000x ceiling is higher than many low-volatility classics in the same visual category but comfortably below the outer reaches of high-volatility titles that carry far larger theoretical maximums in exchange for far harsher cold runs.

Medium volatility is the defining trade-off. A high-vol title in the same theme might offer a ceiling several times larger, but the base game between features would be considerably leaner and the cold runs longer and more punishing. Sticky Diamonds Deluxe takes the other side of that deal: a steadier rhythm, at the cost of a lower top end. That suits players who find the feast-or-famine pattern of high-vol slots unsatisfying over a full session.

The 10-payline structure is more constrained than all-ways or cluster-pay alternatives in the same theme space. Players who like to see wins spreading across many active patterns during the base game may find the fixed-line count limiting. For players who value a clean, predictable pay-table and a readable win shape, however, the traditional layout reads as a feature rather than a drawback.

The seven-feature set, combining a retriggerable Free Games round with Sticky Wilds, a Card Gamble and a Risk Ladder, gives Sticky Diamonds Deluxe more mechanical variety than most classic revivals at comparable volatility. Whether that variety surfaces regularly during a typical session depends on trigger frequency, which the studio has not stated.

The medium-volatility, mid-ceiling profile gives Sticky Diamonds Deluxe a specific fit. It suits:

• Players who want more mechanical variety than a three-reel classic but are not chasing extreme ceilings: the 5,000x cap and steady rhythm give a balanced session without brutal cold runs.
• Fans of the classic diamonds aesthetic who appreciate the Card Gamble and Risk Ladder as player-controlled risk tools: both involve an active decision after a win rather than passive feature-waiting.
• Recreational players on a modest stake: £0.10 minimum, medium volatility and a 96.08% return give reasonable session length per pound at the lower end of the range.
• Players who prefer a clean, fixed-payline layout over cluster pays: 10 lines, a 5x3 grid and stacked symbols produce a predictable win shape that is easy to track.

Who should skip it: GB players who rely on Bonus Buy to access free-spins rounds quickly will find that route closed at UKGC-licensed casinos. Players chasing the largest max-win multipliers in the market will find higher ceilings elsewhere, at the cost of steeper volatility. And anyone who needs the full per-feature detail before committing should note that trigger counts and spin numbers for this title are not yet in the published spec.
