Forget sprawling reel sets. Playson keeps things tight here, dropping you onto a compact 3×3 cabinet that crackles with orange lightning and a single, unsubtle promise: collect diamonds, hold them, and hope the bonus does the rest. Five paylines run across three rows and two diagonals, which sounds modest until you notice the four jackpot plates stacked on the left and the trio of glowing modifier gems perched above the grid.
The base game is honestly a bit minimal. You’ll see card-suit royals, red 7s, golden dice rattling around, and the occasional white Diamond cash symbol carrying its own etched value. That’s really the symbol you’re hunting. Land six or more of them and the Hold and Win round kicks in, where every fresh Diamond resets the re-spin counter and the rest of the grid goes dark. Fill all nine cells and the GRAND lights up at 1,000x your stake.
RTP sits at 95.70%, which is a touch below the industry comfort zone, so that’s the trade-off you’re accepting in exchange for a 15,000x ceiling. Volatility runs very high. The studio’s own data pegs the top hit at roughly one in 50 billion spins, so don’t expect the max-win to wander into your session. Most rounds will feel quiet. Some will explode.
The headline act is the three Supercharged Diamonds, each painted a different colour and each behaving differently inside the bonus. The green Expand gem stretches across extra reel positions. The yellow Multi gem applies a multiplier from x2 up to x32 on neighbouring Diamond values. And the purple Stepper gem hops to fresh cells over consecutive triggers, layering more value as the re-spins continue. Stack two or three of these together in one bonus and the maths starts getting genuinely interesting.
Four fixed jackpots round it out: Mini at 15x, Minor at 30x, Major at 100x, Grand at 1,000x, all paid out inside the Hold and Win round. There’s also a Buy Bonus cart button for players who’d rather skip the wait, with two purchase tiers tucked into the config. Is paying for entry the smart play? Probably not on a 95.70% RTP slot, but the option’s there. As a sister piece to 4 Supercharged Clovers, this one trims the modifier count by one and leans harder on the jewel-and-lightning aesthetic. Compact, loud, and built around a single bonus loop.
