How to cite

Slot Summary

A five-reel grid that keeps ten paylines active gives 777 Jackpot Diamond its compact, traditional base game. Gaming Corps combines Fruit, 777 and Gems imagery with a Hold and Win round, using sticky Diamond prizes and resetting respins to create the main change of pace. The 96.93% RTP and 1,500x ceiling describe a narrower risk and reward range than many larger collector slots.

How It Plays

Regular play uses a 5x3 grid and ten paylines. Fruit, bar and 777 symbols form line wins, keeping the base loop close to a classic machine.

The Diamond symbols provide the switch in format. Landing enough of them moves play into respins, where new Diamonds stay fixed and prolong the sequence.

Theme & Atmosphere

Fruit, Gems and 777 imagery give the slot a traditional machine identity, while the Diamond collector supplies its main modern component.

The Vegas influence appears through familiar bars, fruit and jackpot sevens rather than a detailed narrative setting, making the paytable immediately readable.

Fruit Gems Vegas 777

Features & Win Potential

The Hold and Win feature fixes triggering Diamonds in place and awards three respins. Every additional Diamond locks and returns the counter to three.

Multipliers and additive Diamond values determine the collector total. The optional Bonus Buy provides direct access to the Hold and Win round where available.

Multiplier Respins 5 Reels Bonus Buy RTP range 10 Paylines 96% RTP Hold and Win Additive symbol

Bonus & Free Spins

Five or more Diamond symbols trigger Hold and Win. The round ends when the respins expire without another Diamond or when every position is occupied.

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 (96.93%), with wins capped at its top multiplier (1,500×).

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.
