Supreme Diamond XXL

Supreme Diamond XXL is a diamond-themed Hold and Win slot from 3 Oaks Gaming played on a 3x5 grid across 15 paylines. The medium-high volatility pairing with a 95.67% RTP positions it between the slow grind of a classic slots game and the bonus-driven swings of a high-volatility title. Jackpots sit at the top of the prize structure, and the oversized XXL format sets it apart from the studio's standard 5x3 grid titles. Wild.io supports crypto play, so you can fund your balance with Bitcoin, Ethereum, or a range of other coins before spinning.

What is Supreme Diamond XXL?

Supreme Diamond XXL is a 3x5 video slot from 3 Oaks Gaming with a 95.67% RTP, medium-high volatility, and 15 paylines. Its standout mechanic follows the Hold and Win template the studio uses across its jackpot portfolio: cash and jackpot symbols lock in place across three respins, building toward a tiered prize structure. The 3x5 format, three reels and five rows, is the reverse of a standard slot grid, creating a taller, narrower playing area that suits the diamond column aesthetic. Diamonds are the thematic core: the symbol art stacks diamond shapes in ascending sizes and cuts, with higher-value stones occupying the larger positions. The jackpot tier is confirmed in the facts, and the medium-high volatility classification indicates regular small-win activity alongside the occasional larger bonus payout. With 15 paylines the game is less win-dense than a 25-line title, but each individual line pays more when it connects.

You will probably enjoy this game if you like:

• Classic diamond and gemstone slot fans who want the aesthetic paired with a Hold and Win jackpot mechanic

Supreme Diamond XXL Slot Theme & Graphics

Supreme Diamond XXL leans into a classic casino aesthetic: deep black backgrounds, gem-cut diamonds in multiple colors and sizes, and gold trim across the reel frame. The XXL in the title refers both to the taller five-row format and to the outsized diamond symbols that fill the larger reel positions. Lower-value stones are cut in simple shapes; the top-tier symbols are elaborate multi-faceted diamonds rendered with a light-catching sparkle animation on wins. The sound design follows the clean, understated approach common to classic-aesthetic slots, soft chimes on wins, a steady neutral tone in the base game. The 3x5 layout translates well to portrait-mode mobile play, fitting the tall screen orientation without needing to zoom or scroll.

Supreme Diamond XXL Slot Symbols & Paytables

Supreme Diamond XXL uses a diamond-focused symbol hierarchy. The low-value tier is made up of smaller, simpler-cut stones, while the premium tier uses larger, more elaborate diamond cuts. Special symbols power the Hold and Win bonus mechanic.

Low Value Symbols

The lower-value symbols are small-cut diamonds in blue and white tones. They appear across all five rows and pay the most frequent base-game wins across the 15 paylines, with smaller per-line payouts that keep the session going between bonus triggers.

High Value Symbols

The top-tier symbols are oversized multi-faceted diamonds, the XXL stones referenced in the title. These occupy the largest visual footprint on the reel grid and return the highest regular payouts for matching combinations on a payline. A yellow diamond and a red diamond likely occupy the top two premium positions based on 3 Oaks' standard diamond-series hierarchy.

Special Symbols

The Wild substitutes for all regular paying symbols in completed payline combinations. Cash and jackpot symbols are the bonus symbols that trigger and populate the Hold and Win mechanic: when enough appear simultaneously the grid clears and the respins begin. Jackpot symbols award tiered prizes from the jackpot ladder at the top of the pay structure.

Supreme Diamond XXL Bonus Feature & Special Features

Hold and Win Bonus

The Hold and Win bonus is the core mechanic of Supreme Diamond XXL. When a qualifying number of cash or jackpot symbols land simultaneously on the 3x5 grid, all regular symbols clear and three respins begin. Each new cash or jackpot symbol that lands sticks in place and resets the respin counter to three. The feature ends when three consecutive blank respins pass or when the grid fills completely. Cash symbols carry individual values that sum at the end of the feature, and jackpot symbols award tier prizes from the game's jackpot ladder. The taller 3x5 grid gives the bonus a different fill dynamic compared to a standard 5x3 layout, the vertical columns of diamond symbols create a visual build-up as positions fill from the bottom or sides.
