In-game Jackpot

Five reels, three rows, ten lines across the grid. The symbol set pairs fruit on the lower end with a single high-value symbol and a Wild that substitutes across the board and pays up to ×10 for five of a kind. The real motion in the base game, though, happens above the reels. Alongside the regular symbols, coloured coins land in red, blue, and green — and each one takes flight the moment it settles, tracing a trail into the diamond of its matching colour. The three Royal Diamonds visibly fill as coins arrive: gems rise, coins pile up, and a diamond on the brink begins to shine and pulse. It’s the 3 Royal Diamonds slot telling you which power is closest to waking. When the diamonds activate, the reels fade away, the triggering coins hold their place, and the Hold & Win bonus begins — carrying the powers of every diamond that fired.

The three diamonds are what set the 3 Royal Diamonds online slot apart, and each changes the bonus in its own way. The Red Diamond is Double: it creates a full copy of the playing field, and from that point the two fields spin independently — one can finish while the other keeps going, and both can claim the bonus jackpot. The Blue Diamond is Life: the first time the spin counter runs dry, a glow around the counter fires and restores the spins, once per bonus — a second chance built directly into the round. The Green Diamond is Multi: on any bonus spin it can scatter multipliers into random cells, including empty ones, and when a new multiplier lands on a cell that already holds one, the two values simply add together — ×3 onto an existing ×5 becomes ×8. The diamonds combine, too: enter with red and blue active and the duplicated field appears first, then both spin counters light up with their extra life. One diamond makes a bonus; three diamonds make an event.

The bonus itself is a 5×3 Hold & Win with the diamond powers layered on top. Coins lock in place as they land, the counter keeps the round alive, and every coin on the field counts toward the finale. Fill all fifteen positions and the Grand Jackpot is yours — and when thirteen coins are already locked, the last two empty cells run a special anticipation on every spin, so the chase for the full grid is impossible to miss. At the close of the round the sequence resolves in order: Mystery Coins reveal what they’ve been hiding, the multipliers left by the Green Diamond apply to every coin they touch, and then the collection sweeps the field, coin by coin, into the total.

Mystery Coins run through both halves of the game. In the base game, a Mystery Coin flies into one of the three diamonds at random, feeding whichever power fate picks. In the Hold & Win, a Mystery Coin keeps its secret for the whole round — it locks in place like any other coin but only shows its face when the spins are over, revealing either a regular coin or a jackpot coin just before the multipliers apply and the collection begins. It’s the last card the 3 Royal Diamonds slot turns over, and it can change the shape of the entire payout.

Three options shape how you reach the diamonds. The first Bonus Buy launches the Hold & Win with one to three diamonds chosen at random — the gems flash in sequence before the final count locks in. The second Bonus Buy guarantees the full set, opening the bonus with all three diamond powers active and a random spread of starting coins. And the Double Chance Bonus Bet roughly doubles how often the bonus triggers in normal play. Buy the powers outright or raise the odds and let the coins do the charging — the 3 Royal Diamonds online slot leaves the route to you.

Four jackpot tiers live inside the game. Mini, Minor, and Major jackpots can appear on the coins themselves, landing in the base game and the bonus alike. The Grand Jackpot stands apart: it’s awarded for completely filling the 5×3 field in the Hold & Win bonus — fifteen coins, no gaps. And because the Red Diamond duplicates the field, a doubled bonus gives you two grids chasing that full-house finish at the same time.
