Slot Summary

Collecting crystals while the reel set expands gives Dwarf Mine a route toward its more valuable spin modes. Yggdrasil Gaming turns the mine itself into a changing play area, with drill symbols opening extra space and Free Spins offering different collection goals. The 96.8% RTP and x3904.00 maximum win place the payout ceiling behind a sequence of grid expansion, crystal gathering, and feature access.

How It Plays

The reel set begins in a compact state and gains extra rows when drill symbols appear. Each expansion increases the available symbol positions and winning ways.

Crystals appear in the added space, so expanding the grid also advances a collection task. That connects ordinary spins directly to later Free Spins access.

Theme & Atmosphere

Fantasy and Gems themes define the underground mine, where a dwarf operates a drilling machine to reach treasure and crystal deposits below the starting grid.

Magic enters through the collectible crystals and their ability to unlock a distinct spin mode, giving the mine setting a functional role in the rules.

Features & Win Potential

Expanding Reels and Reelset Changing enlarge the play area, increasing the available ways while exposing new positions for Symbols collection and possible Wild coverage.

Collected crystals lead toward Free Spins, while Expanding Wilds can occupy more of the enlarged reel set after the additional rows have opened.

Bonus & Free Spins

Free Spins can follow the appearance of 3 drill symbols, with the expanded reel arrangement carrying into the feature and increasing the available winning positions.

A separate collection route uses matching crystals gathered from added rows, linking Symbols collection to another Free Spins mode with more valuable symbols.

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 (96.80%), with wins capped at its top multiplier (3,904×).

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.
