Brilliant Diamonds: Hold & Win

Isoftbet dresses Brilliant Diamonds Hold & Win in glossy luxury goods, spreading champagne bottles, watches, sports cars and private jets across a 5x3 grid with 25 fixed paylines, the whole scene lit by a rotating blue diamond glow in the background. Released in February 2022, the game leans entirely on cash-symbol collection rather than a themed storyline.

The paytable splits between four card-rank low pays, J through A, worth 2x to 4x the stake for five in a row, and four premium items — champagne, a watch, a car and a private jet — paying 6x to 16x for the same length. A wild lands stacked on any reel, standing in for every regular symbol, and pays out at the jet's rate when it fills a line on its own.

Diamond Modifiers can fire on any base spin without warning, either handing over an instant win worth more than 20x the bet or opening the Hold & Win Respins round outright. When the modifier triggers, some of the ordinary Platinum Diamond symbols already on the grid are converted into Gold Multiplier Diamonds before the respins begin.

Respins start once five or more Platinum or Gold Diamonds sit on the grid, granting three spins to fill the remaining positions. Every new diamond that lands locks in place and resets the counter back to three, and the round only ends when the board is full or the respins run out. Locked diamonds reveal either a cash value or one of three fixed prizes — 20x for a Minor, 200x for a Major, or 1,000x for a Grand — while Gold Diamonds carry a multiplier that opens at 1x and rises by one for every Gold Diamond present on the triggering spin, though no further Gold Diamonds can appear once the respins themselves are running.

Isoftbet quotes 96.9% as the headline return for Brilliant Diamonds Hold & Win, alongside a 96.0% configuration and a separate 96.90% setting for anyone who buys straight into the feature for 50x the total bet. Medium volatility and a 26.2% hit frequency keep the base game ticking over between the bigger diamond-fuelled rounds, with a maximum win of 5,440x the stake and stakes running from 0.25 up to 25 per spin.
