Diamonds Diamonds Diamonds Hold and Win Slot by Booming Games

The title is a joke that lands. Just the word 'diamonds' three times, on a purple velvet backdrop with gold beam accents radiating outward, like a pawnshop window trying to look upmarket. The base reels run classic 3x3 with card suits (spades, hearts, clubs), brass bells, and coloured diamond symbols carrying either prize multipliers (3x visible on the blue diamond) or the four jackpot tags.

Four fixed pots hang on the left rail: Grand 1000x, Major 500x, Minor 100x, Mini 20x. The spread is wider than most Booming Games slots, with a meaningful gap between tiers that keeps the Grand feeling distant even when you're deep in a bonus.

Diamond Rain is the trigger to watch. Random base-game events spray the grid with various diamond values, and when enough land, the Hold & Win bonus kicks in - but with an expanded 5x3 grid instead of the base 3x3, giving you two extra reels' worth of positions for sticky diamonds. Three respins, standard reset on new symbols, same Booming framework. Fill the whole grid and the Grand pays out.

The real twist is Super Hold and Win, a second bonus mode that runs the same sticky mechanic but doubles every prize on the final payout. How you enter either mode depends on how the Diamond Rain lands, and Super isn't just a bigger version, it's a separate trigger with its own approach. This keeps bonus rounds varied, which matters when the base game is as stripped-down as this (no free spins, no cascading wins, just stacked wilds and line hits).

Boost+ sits in the corner as an optional ante-style side bet at 3x the base stake. It increases the trigger chance for Diamond Rain and the stacked wilds landing more often. At 3x base though, you're burning through balance three times as fast for trigger acceleration, and the math only really pays off if you hit the bonus faster than average. Math-savvy players will do the calculation. Most will just leave it off.

A small slot in the best sense - simple grid, focused mechanic, not trying to be seven things at once. The 5000x cap won't impress but fits the scope.
