Supreme Diamond XXL by 3 Oaks Gaming: 1xBet Game Profile
Supreme Diamond XXL is a 3 Oaks Gaming slot built on a 3x5 grid with 15 fixed lines. Its reels mix classic gem symbols with a modern Collect mechanic. The developer lists the release month as May 2026.
The Demo and Its Controls
3 Oaks Gaming provides a demo of Supreme Diamond XXL on its product page. The demo lets you spin the reels without risking real money. You can set your bet and read the paytable before play. There is no need to register to try the demo, and the controls follow the studio's standard layout. A source link to the official product page appears at the end of this article.
Meet the Collect Symbol
The Collect Symbol is a black Diamond that anchors the main gameplay. It absorbs the values of any visible Bonus Symbols on the reels. Those absorbed values are added to the Collect Symbol's own value during the feature. Bonus Symbols can carry fixed Mini, Minor, Major or Grand Jackpot prizes.
Hold & Win and the Bonus Game
In the Hold & Win Bonus Game, up to five Collect Symbols can land on reel two. They stay locked in place for the whole round. They gather the values of all visible Bonus Symbols, and when a Bonus Symbol's value is taken, that symbol disappears. New Bonus Symbols can then land, keeping fresh values flowing into the Collect Symbols.
The developer specification lists this as a Bonus Game with up to five collectors. A separate Super Bonus Game is also listed.
Trigger Paths
There are several ways to enter the Bonus Game. A combination of Bonus and Collect Symbols on the reels can trigger it. The Lucky Spin feature can also start the round, and activating the Diamond Metre is a third path. These routes are documented by the developer.
Super Bonus Game
The Super Bonus Game is a distinct entry that guarantees a minimum of three Collect Symbols at the start of the round. This changes the opening position compared with the standard Bonus Game, where Collect Symbols are not guaranteed for the first spin.
1xBet Context and Bonus Shop
The Bonus Shop menu lets players purchase access to the Bonus Game and the Super Bonus Game. Prices are set by the operator and appear only inside the game client. On 1xBet, the catalogue URL of Supreme Diamond XXL is the access point once you are signed in.
Jackpot Values and Settlement
The developer lists a Grand Jackpot at x1000. Fixed Mini, Minor and Major prizes also appear as Bonus Symbol values. The Grand Jackpot x1000 is the largest fixed award named in the specification.

Bonus Game Settlement in Detail
During the Hold & Win round, Collect Symbols lock on reel two. Each Collect Symbol absorbs the value of every visible Bonus Symbol. After collection, the drained Bonus Symbol leaves the grid. A new Bonus Symbol can land in its place. This cycle continues for the duration of the round.
What the Collect Symbol Absorbs
Only Bonus Symbols carry collectable values. Jackpot symbols with fixed Mini, Minor, Major or Grand tiers are among those values. A Collect Symbol does not absorb other Collect Symbols, only the values presented by Bonus Symbols on the reels.
