ENJOY Gaming Debuts Multiboost Mechanic in Diamonds XXL Hold and Win Slot

ENJOY Gaming has introduced Diamonds XXL Multiboost: Hold and Win, a new entry in its Diamonds XXL series, debuting on 10 September 2026. This release is built around a Multiboost mechanic that collects and multiplies bonus and jackpot values, providing a more dynamic play experience for both operators and players.

Diamonds XXL Multiboost: Hold and Win – Core Game Features

Diamonds XXL Multiboost: Hold and Win is a video slot set on a 3x5 reel grid with 15 fixed paylines. The slot includes a red 7 wild symbol, substituting for all standard icons, and is designed to maintain a familiar structure for venues already running Diamonds XXL titles. The standout addition is the new Multiboost symbol, positioned exclusively on the central reel. This symbol collects the total value of all visible bonus and jackpot icons, then applies a multiplier of up to 20x, randomly determined on each trigger.

How the Multiboost Mechanic Works

The core of the innovation is the Multiboost coin:

• Appears only on reel three.
• When it lands, it aggregates the values from all bonus and jackpot symbols in view.
• The total is then multiplied by a randomly selected multiplier, with a ceiling of 20x.

"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," said Svitlana Lytvinenko, Product Owner at ENJOY Gaming.

Hold and Win Bonus Design and Jackpots

During the Hold and Win bonus game, players start with three respins. Every new bonus, jackpot, boost, or multiboost symbol landing resets the respin counter, while boost and multiboost symbols remain locked until the bonus round concludes. The slot offers four static jackpots, with the grand jackpot paying up to 1000x the player’s stake.

• Hold and Win mode is triggered by bonus features and is a key engagement driver for players familiar with the series.
• Sticky coins (boost and multiboost) increase the chance for significant wins within the feature.

Flexible Betting, Bonus Buy, and New Engagement Hooks

Diamonds XXL Multiboost: Hold and Win provides a range of bet customization tools for casino operators and end users. Players can activate:

• Extra Bet Options: Double Chance or Boosted Spin improve the probability of triggering bonus rounds.
• Three Bonus Buy Features: These include a Multiboost-only bonus game, catering to players seeking direct access to enhanced win potential.

An extra bonus trigger can activate the Hold and Win feature even following a non-winning spin, adding an additional layer of unpredictability.

Product Owner Perspective and Operator Appeal

From the developer’s standpoint, the release is engineered to offer a fresh engagement angle built on the foundation of a proven game series.

“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,” said Lytvinenko.

For operators following news in the slot segment, the addition of a multiplier-driven mechanic is positioned to increase retention without altering the familiar Diamonds XXL experience. The launch underlines ENJOY Gaming’s ongoing strategy of expanding established series with differentiated features that still maintain accessibility for returning players.

Outlook for Multiboost Slot Mechanics in B2B iGaming

The introduction of the Multiboost mechanic in this context illustrates a willingness by ENJOY Gaming to compete on multiplier volatility, a trait that has become a performance driver in the Hold and Win genre across regulated markets. The mix of sticky coins, scalable multipliers, and guaranteed bet flexibility situates Diamonds XXL Multiboost: Hold and Win in the competitive tier for B2B slot portfolios.

Operators and affiliates can expect support for the game’s promotion through bonus buy options and customizable bet levels, designed for varied market and player preferences.
