How the Game Plays

15 Diamonds is a classic-inspired slot developed by Playtech, designed as an exclusive for select operators. The game features a high-gloss 5x3 grid populated by traditional fruit machine symbols, including cherries, plums, and golden bells, alongside high-value lucky 7s. While the base game is straightforward with its five fixed paylines, the focus is entirely on the jewelry-themed bonus triggers. Winning combinations are formed from left to right, but the appearance of the sparkling diamond symbols shifts the action toward the game's progressive potential.

Hold & Respin Feature Explained

The core of the experience is the Hold & Respin mechanic, which is activated by landing a specific set of diamond bonus symbols. Once triggered, the standard reels disappear, leaving only the diamonds that initiated the round locked in their positions. Players are granted a set of respins to land additional diamonds; each successful hit resets the spin counter. The round continues until no more spins remain or the entire grid is covered.

Tiered Jackpots Explained

This slot includes a tiered jackpot system consisting of Mini, Minor, Major, and Grand prizes. While the smaller jackpots can be awarded randomly or via specific bonus combinations, the Grand Jackpot is the game's ultimate goal. It is awarded only when a player successfully fills all 15 positions on the grid with diamond symbols during the Hold & Respin feature, typically resulting in a payout of 1,000x the stake.
