ENJOY Gaming adds Multiboost mechanic to Diamonds XXL Hold and Win slot

ENJOY Gaming has released Diamonds XXL Multiboost: Hold and Win, expanding its Diamonds XXL slot series with a new multiplier feature. The title launches on 10 September 2026.

The game is a 3x5 slot with 15 fixed paylines. It uses a red 7 wild that substitutes for all regular symbols.

The new multiboost symbol 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. During the Hold and Win bonus, the round starts with three respins that reset on every new bonus, jackpot, boost or multiboost symbol, while boost and multiboost coins remain sticky until the feature ends.

Four fixed jackpots are available, with the grand jackpot listed at up to 1000x. The game also includes an extra bonus feature that can trigger the bonus game on a non-winning spin.

Players can enable two extra bet options—double chance and boosted spin—or use three bonus buy modes, including a multiboost-only bonus game. Svitlana Lytvinenko, Product Owner at ENJOY Gaming, said: “The multiboost mechanic adds a real multiplier edge on top of the Hold and Win format operators already know performs well, so it slots straight into the Diamonds XXL series while raising the ceiling on what a single round can deliver.

“We wanted this release to give operators a proven, familiar framework with a fresh hook. Multiboost gives them a strong new angle to market for a series that already has a loyal following, without asking players to learn something completely new.”
