ENJOY has expanded its successful Diamonds XXL series with the release of Diamonds XXL Multiboost: Hold and Win, adding a bold new multiplier mechanic to the line's signature precious gem theme.

The 3x5, 15 fixed pay line slot keeps the base game fast and easy to follow, with the red 7 wild substituting for all regular symbols.

The action centres on the new Multiboost Symbol, which lands on the middle reel, collects the value of all visible bonus and jackpot symbols, and multiplies the total by a random multiplier up to 20x. It can retrigger repeatedly during the Hold and Win Bonus Game, which starts with three respins that reset on every new bonus, jackpot, boost or multiboost symbol, while boost and multiboost coins stay sticky until the round ends.

Four fixed Jackpots, with values reaching the 1000x Grand Jackpot, are up for grabs throughout, and the extra bonus feature can trigger the bonus game even on a non-winning spin.

Players can shape the pace with two extra bet options, double chance and boosted spin, or buy straight into the action through three bonus buy modes, including a multiboost-only bonus game.
