Slot Summary

Gemstones supply the treasure-room setting for Jackpot Gem Rush, Mascot Gaming's slot with a separate coin-collection round. Its clearest objective is filling the bonus board to reach the Grand prize. Ordinary gem combinations and the Hold and Win feature ask the player to follow different things: matching symbols first, occupied positions once the collection round begins.

How It Plays

The base game uses fixed paylines, with gem combinations paying from the left side of the reels. Gem symbols have different values, so matching quantity alone does not determine the payout.

During Hold and Win, collected symbols remain in place while the remaining positions respin. Attention shifts from making a line combination to adding prizes before the collection round finishes.

Bonus & Free Spins

Free spins provide a separate feature alongside Hold and Win. Scatter symbols open this round, whereas the collecting bonus accumulates prizes through respins and reserves its Grand award for a completely occupied grid.

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-High). The model is calibrated so the average return equals this slot's published RTP (96.01%), with wins capped at its top multiplier (5,000×).

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.
