Slot Summary

For anyone drawn to a bonus multiplier that keeps climbing through repeated wins, Diamond Mine Megaways makes free spins the central attraction. Blueprint Gaming's mining slot connects exploding symbols with the work of digging for treasure. Its changing reel sizes keep the excavation moving, while the bonus gives successive cascades greater weight.

How It Plays

Matching symbols pay across adjacent reels from the left, regardless of their vertical position. Winning symbols disappear and replacements fall into the empty spaces for another evaluation.

An extra strip above the middle reels contributes symbols to combinations. It refills from the right during cascades, while the main reel symbols arrive from above.

Features & Win Potential

TNT symbols transform together into the same randomly selected symbol. They cannot reveal scatters, so their conversion can help regular combinations without directly supplying the free-spin trigger.

Wilds appear only in the extra positions above the middle reels. They substitute for ordinary paying symbols but exclude scatters, giving that upper strip a distinct role.

High volatility Free Spins 6 Reels Multiplier Scatter Symbol Wild Symbol Cascading Megaways RTP range 96% RTP Avalanche Colossal Reels Grid Free Spins Multiplier Substitution Symbols Substitution of wining symbols

Bonus & Free Spins

Four scatters award 12 free spins, with five more for each additional triggering scatter. The bonus multiplier begins at 1x and rises by one after each cascade, without a preset multiplier ceiling.

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 (High). The model is calibrated so the average return equals this slot's published RTP (96.43%), with wins capped at its top multiplier (10,000×).

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.
