Slot Summary

For players who want classic 777 imagery with a collecting bonus, this Gaming Corps release pairs medium volatility and an x2500.00 ceiling with a Fruit, Gems, Luxury, and Vegas presentation. Its defining element is not the familiar symbols but the way Diamond prizes feed a Hold and Win round, where Amethyst multipliers can alter collected values.

How It Plays

Base play uses five reels, three rows, and ten paylines. Matching symbols pay from left to right across adjacent reels, keeping ordinary spins easy to read.

Landing at least five Diamond symbols changes the play pattern from line evaluation to collection. Triggering Diamonds remain fixed while the available positions respin.

Theme & Atmosphere

Fruit symbols and the 777 motif provide the familiar core, while the Gems theme supplies the Diamond and Amethyst symbols that matter mechanically.

Luxury and Vegas cues frame the game as a polished casino-floor machine, with prize imagery taking priority over characters, narrative, or location changes.

Fruit Gems Vegas Luxury

Features & Win Potential

Sticky Symbols preserve collected Diamonds during Respins, and every newly landed Diamond restores the counter. The Additive symbol role belongs to the Amethyst multiplier.

Fixed Jackpots and the 777 Jackpot sit outside the ordinary line-win rhythm. Bonus Bet and RTP range options can alter the configured version or access route.

Multiplier Respins Bonus Game RTP range Bonus symbols Hold and Win Bonus Bet Random multiplier Fixed Jackpots Additive symbol Sticky Symbols

Bonus & Free Spins

The Hold and Win Bonus Game begins with three Respins after at least five Diamonds land. Existing Diamonds stay fixed, and each additional Diamond resets the counter.

Amethyst symbols apply Multipliers to collected prizes during the Bonus Game. The round finishes when no Respins remain or every available position has been filled.

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 (95.80%), with wins capped at its top multiplier (2,500×).

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.
