New 3×5 Slot Introduces Innovative Multiboost Multiplier Mechanic and Fixed Jackpots Up to 1,000x
iGaming content developer ENJOY Gaming has officially expanded its successful Diamonds XXL portfolio with the release of Diamonds XXL Multiboost: Hold and Win. The latest title infuses the franchise’s signature gem-themed environment with a dynamic multiplier mechanic designed to elevate the traditional Hold and Win gameplay experience.
Built on a fast-paced 3×5 grid featuring 15 fixed paylines, the base game incorporates red 7 wild symbols that substitute for all regular icons. The central gameplay innovation revolves around the new multiboost symbol, which lands on the middle reel to collect values from all visible bonus and jackpot symbols before multiplying the total by a random multiplier worth up to 20x.
Enhanced Hold and Win Bonus Mechanics
The Hold and Win feature initiates with three respins, resetting whenever a new bonus, jackpot, boost, or multiboost symbol lands, with boost and multiboost coins remaining sticky throughout the round. Players can compete for four fixed jackpots reaching up to 1,000x the stake for the Grand Jackpot. Additionally, an extra bonus feature can trigger organically even on non-winning spins.
For customized engagement, the title offers two extra bet options, double chance and boosted spin, alongside three distinct bonus buy modes, including a dedicated multiboost-only feature access.
Executive Insights
Svitlana Lytvinenko, Product Owner at ENJOY Gaming, commented on the release:
“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.”
