Diamond Hustle Slot by Evoplay

Sticky Bonus symbols pin themselves to the grid between spins and stay there until the bonus triggers. Their values range from 5x to 9x, and since the entire 3x3 grid consists of special symbols - no filler, no card suits - those sticky positions build up between rounds. Three symbols lining up on the middle row starts the hold-and-win round, or the buy bonus skips the base game entirely.

Inside the bonus, the standard 3-respin countdown applies. But Magic Stone changes how the math works. Each one absorbs every value and jackpot currently on the grid, copying them into its own total. Drop a second Magic Stone and it copies everything again, including what the first one already collected. Four jackpot tiers stack on the left side of the screen - Mini, Mega, Super, and Grand - and Mystery Jackpot symbols guarantee one of those tiers when they reveal at the end of the round. Regular Mystery symbols transform into any type except Sticky Bonus when the bonus concludes. Fill all nine positions and Grand adds to the total.

Diamond Boost fires randomly, placing position-specific multipliers (x2 through x9) onto the grid. When it hits during the base game, it also forces three symbols onto the middle row, guaranteeing an immediate bonus entry. Those multipliers stack on repeat activations and apply at the end of the bonus round to whatever occupies their position. Deep violet crystal shards fill the background behind a gold-trimmed grid dotted with faceted diamond symbols in blue and white, the whole palette running purple, gold, and ice. A well-timed Diamond Boost stacking x9 on a Magic Stone that's been snowballing all round is how you reach the 4,312x ceiling.
