Slot Summary

Land at least 5 Diamond symbols and 777 Jackpot Diamond Hold and Win Deluxe leaves its 10-line base game for a sticky-symbol respin round. Gaming Corps positions this Deluxe release as a continuation of the original 777 Jackpot Diamond formula, adding a Topaz symbol that increases Diamond values and raising the maximum to x2000.00. The result keeps the series' Retro identity while giving the Hold and Win sequence a new value-building device.

How It Plays

The base game uses 5 reels, 3 rows, and 10 paylines. Qualifying combinations form from left to right, with only the highest win paid on each active line.

The 777 symbol carries the largest regular-line award. Landing 5 on one payline reaches the listed x2000.00 maximum without requiring the respin feature.

Theme & Atmosphere

Fruit, 777, and Retro references place the game close to a classic machine, while the video-slot presentation supplies the feature controls and bonus structure.

Gems provide the bridge between the Vegas-style base game and the Hold and Win round. Diamonds act as the principal prize carriers once the reels change mode.

Fruit Retro Gems Vegas 777

Features & Win Potential

Hold and Win uses Bonus symbols that remain fixed while the other positions respin. Each newly landed qualifying symbol restores the counter to 3.

The Multiplier values attached to collected symbols determine the final feature award, while Bonus Buy provides a separate route into the same Bonus Game.

Multiplier Respins Medium volatility Bonus Game Bonus Buy Bonus symbols Hold and Win

Bonus & Free Spins

The Hold and Win Bonus Game begins with 3 respins after at least 5 Diamonds land. Each new Diamond remains Sticky and resets the available respins to 3.

Bonus Buy costs 50 times the bet and opens the feature immediately. The round ends when the respin counter reaches 0 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 (96.10%), with wins capped at its top multiplier (2,000×).

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.
