About Supreme Diamond XXL
Mesmerising gemstones glow on retro-inspired reels, and the respin round is where this 3 Oaks game comes alive. Keep your eyes on the black stones: they're the collectors, and in the bonus they can stack up on a single reel.
Inside Supreme Diamond XXL
Black Diamond collector
The Collect symbol is a dazzling black Diamond. When it lands, it absorbs the values of every Bonus symbol in view, so every value showing on the reels can be swept up in one go.
Collected, cleared, refilled
In the Hold & Win Bonus Game up to five Collect symbols can land on reel two and stay locked. After they gather the Bonus values, including any Mini to Grand jackpots, those symbols are removed so fresh ones can drop.
