Slot Summary

Take the line win or send it into the Gamble decision: Cool Diamonds II makes that choice the main interruption to its regular spin cycle. Amatic pairs the optional card game with a 96% RTP, 10 fixed paylines, and a five-reel jewel format. Wild and Scatter symbols supply the other changes to play, leaving the base game deliberately direct and focused on repeated line results.

How It Plays

Every spin uses five reels, three rows, and 10 fixed paylines. Standard combinations run from left to right, and the line count remains fixed while the stake changes.

After an eligible payout, the Gamble option creates the key decision. The player may keep the result or risk part of it through a card prediction.

Theme & Atmosphere

Gems and Luxury define the paytable, with diamonds, rings, gold bars, and treasure chests presenting value through familiar physical objects rather than a character-led story.

The jewel display gives the slot a straightforward casino identity. Its visual emphasis stays on prize hierarchy, making premium symbols easy to distinguish from lower-value entries.

Gems Crown Luxury Love

Features & Win Potential

The Wild substitutes for ordinary paying symbols and supports line formation across the fixed grid. Scatter symbols can award independently of the regular left-to-right pattern.

The Gamble feature follows eligible wins and offers color or suit predictions. Choosing color can double the risked amount, while a correct suit prediction can multiply it by four.

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). The model is calibrated so the average return equals this slot's published RTP (96.00%), with wins capped at its top multiplier (1,000×).

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.

01What happens in the Gamble feature?

After an eligible win, the player can risk half or all of that amount by predicting a hidden card's color or suit. An incorrect choice loses the amount risked.

02What is the RTP of Cool Diamonds II?

The cataloged RTP is 96%. The game uses five reels and 10 fixed paylines, so changing the stake does not alter the number of active lines.

03Which special symbols are present?

Cool Diamonds II includes Wild and Scatter symbols. The Wild substitutes for regular symbols, while Scatter combinations produce awards independently of standard left-to-right line wins.
