Supreme Diamond XXL Online Video Slot
Supreme Diamond XXL is a 3 Oaks Gaming video slot built around bright gemstone reels, 15 paylines, and a Hold & Win bonus chase. I like this one for players who want a clean classic-slot surface, but still want the bonus round to feel busier than a plain coin collector.
Quick take: Supreme Diamond XXL keeps the base game simple, then puts most of the excitement into Collect symbols, jackpot prizes, and a Bonus Shop that can jump straight into the feature.
Theme and Gameplay
The game uses a dark, glossy jewel look with diamonds, BAR symbols, sevens, and bright colored gems across a 5×3 layout. It feels like a modernized casino-floor fruit machine: easy to read, quick to understand, and focused more on the bonus build-up than on a complicated symbol map.
During regular spins, the main thing I found myself watching was the diamond-style bonus setup. The base game does not try to tell a big story, which actually works here. The appeal is in seeing the reels light up with cash values and hoping the Collect setup turns a modest spin into something bigger.
Slot Features
The centerpiece is the Hold & Win bonus game. Bonus symbols can carry values, while the Collect symbol gathers those values and keeps the round moving. In the bonus, up to five Collect symbols may appear on reel two, and they stay locked while collecting visible prizes from the board.
The jackpot structure gives the feature a clear target. Mini, Minor, Major, and Grand jackpot values can appear during the round, and the Bonus Shop adds extra flexibility for players who prefer buying into the bonus where allowed. The Super Bonus is the more aggressive route because it starts with extra Collect-symbol strength.
Feature focus: The best part is the Collect-symbol rhythm. Instead of only waiting for coins to stick, you are watching reel two become the engine that gathers values and clears space for more prizes.
My Thoughts On This Slot
Supreme Diamond XXL is not the flashiest 3 Oaks release, but it does the Hold & Win job well. The 15-line setup makes it approachable, and the bonus round has enough movement to feel more active than a basic jackpot respin.
I would put this in the “steady bonus chaser” category. It is best for players who like jewel or fruit-machine slots, fixed jackpot ladders, and clear bonus goals. If you want wild animations and constant side features, it may feel restrained, but for a focused Hold & Win session it lands nicely.
My take: A polished 3 Oaks Hold & Win slot with a simple face and a stronger-than-expected Collect-symbol bonus round.
