Slot Summary

Five reels, 3 rows, and 10 paylines form a compact Classic slot where one diamond can change the visible reel space. Expansion of Diamonds uses Fruit, Gems, and Star imagery, but its defining object is the Expanding Wild on the middle 3 reels. SYNOT Games pairs that direct mechanic with 2 Scatter symbols, a Gamble option, a 98.05% RTP setting, and an x500 maximum win.

How It Plays

Ten paylines evaluate combinations across the 5x3 format. Two Scatter symbols can pay from any position rather than following the usual line requirement.

The central reels carry the main mechanical change. When the Diamond Wild contributes to a win, it expands across its reel before the final award is settled.

Theme & Atmosphere

Classic Fruit symbols supply most of the recognizable machine language, while Gems and a Star move the presentation away from a plain produce-only paytable.

The diamond is both the visual centerpiece and the functional Wild, giving the theme a direct role in how the most important symbol behaves.

Fruit Gems Star Classic

Features & Win Potential

The Expanding Wild can appear on reels 2, 3, and 4. When it takes part in a qualifying win, it covers the full reel.

Scatter Symbols pay independently of paylines, while the Risk/Gamble game offers a separate card-color decision after an eligible win has already been formed.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium-Low). The model is calibrated so the average return equals this slot's published RTP (98.05%), with wins capped at its top multiplier (500×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
