Brilliant Diamonds: Hold & Win

Diamonds That Lock and Pay

How the Hold & Win Respins Work

The feature triggers when five or more platinum or gold diamond symbols land at once. Those diamonds freeze in place and you are awarded three respins. Each new diamond that lands resets the respin counter back to three. The round continues until the respins run out or all 15 grid positions are filled with diamonds.

Three jackpot tiers sit inside this feature: Minor at 20x stake, Major at 200x stake, and Grand at 1,000x stake. These values are attached to individual diamond symbols and are collected when the round ends. The structure gives the respin phase clear targets rather than open-ended accumulation.

Gold Multipliers and the Max Win

Gold diamonds carry multiplier values that add to a cumulative feature multiplier. When a board fills with a mix of jackpot diamonds and stacked Gold multipliers, the totals climb quickly. This combination is what drives the 5,440x maximum win. In practice that ceiling needs a near-perfect respin round, so most feature exits land somewhere in the moderate range built from smaller jackpot hits and modest multipliers.

Base Game and the Diamond Modifier

During regular spins, stacked Wilds can land on any reel and substitute for all standard pay symbols. The standout base-game extra is the Diamond Modifier, a random trigger that either guarantees a win of 20x or more or sends you straight into the Hold & Win respins. There is no separate free spins mode here; the respin feature is the sole bonus round.

RTP and Volatility

The base RTP is 96%, exactly at the average for online slots. Volatility is medium, so the base game and the Diamond Modifier keep wins landing with reasonable frequency rather than forcing long cold stretches between features. The bigger payouts still concentrate inside the respin round, but the wait to get there tends to be shorter than on high-variance titles. Medium volatility still carries real swing, so individual sessions can run cold.

Betting Range and Bonus Buy

Stakes run from 0.10 per spin, covering casual play through to higher rollers. A Bonus Buy option costs 50x your total bet and drops you directly into the Hold & Win respins, raising the effective RTP to 96%. Note that Bonus Buy is not offered to UK players, so on regulated UK casinos you trigger the feature through normal play and the Diamond Modifier only.

Play the Free Demo

Spin 40 to 60 rounds to see how often the Diamond Modifier fires and how fast the board fills once respins begin, then decide whether the pace suits you.
