Diamonds XXL Multiboost by Enjoy Gaming sets gems and diamonds across a compact five-reel, three-row grid. Its 15 fixed paylines give ordinary spins a familiar line-based rhythm, with three matching symbols paying along a line. The red 7 Wild can substitute for regular symbols. Hold and Win shifts the focus from line matches to a sticky prize board and Multiboost collection.
Quick take: A sticky Hold and Win board gives Multiboost a growing set of visible prizes to collect.
Theme and Gameplay
The gem-and-diamond theme frames two goals: matching symbols across fixed lines and building value on the Hold and Win board. On ordinary spins, the red 7 is worth watching because it can fill in for a regular symbol. Matching symbols still need to follow a paying line, so their positions matter as much as their number. Once the bonus starts, attention shifts to the open spaces and the coins that stay in place.
Slot Features
Hold and Win begins with three respins. A new bonus, jackpot, boost or multiboost symbol resets the count, while Boost and Multiboost coins remain sticky for the round. That gives each new qualifying symbol a clear job: extend the chase and add to the board.
A Multiboost collects the visible bonus and jackpot values, then applies a multiplier. The multiplier can raise the collected amount, but its effect depends on the values already on screen. Three bonus-buy modes are available, including a Multiboost-only bonus game. Buying entry gives access to the feature without guaranteeing what it will pay.
Feature focus: A qualifying symbol restores the full three-respin countdown, so even a late arrival gives the board more time to develop.
RTP and Win Potential
Jackpots reach up to 1,000x, while Multiboost applies a random multiplier of up to 20x to the visible bonus and jackpot values it collects. The prize chase is therefore about both the values gathered and the multiplier applied to them. A larger multiplier has more to work with when the collected prizes are worth more.
My Thoughts On This Slot
The feature gives the board a readable sense of suspense. Each qualifying symbol restores the respins, and sticky coins make the developing collection easy to follow. Multiboost adds an appealing payoff possibility because its multiplier acts on visible prizes, while the three-respin limit keeps empty spaces relevant.
The fixed paylines provide a simple rhythm between bonus rounds. This should appeal to players who enjoy watching a prize board build and can accept that its progress depends on more qualifying symbols landing. Those who prefer line wins to be the main event may find the bonus chase takes up more of the game's identity.
Final Take: A clear-cut line slot whose sticky prize board gives the bonus its pull.
