Dwarf Mine slot review
Deep underground, where torchlight barely reaches the walls, a dwarven digger bores deeper in search of treasure — and this is exactly where Yggdrasil hid one of their mechanically richest slots. Dwarf Mine doesn't just expand the playing field — it grows with the game: crystals charge the machine, drills unlock free spins, and collections bring super-symbols with above-average payouts. The mine runs by its own rules.
The basics: 1,024 to 16,807 ways to win, RTP 96.8%, volatility — medium-high, maximum win — €488,000. The field expands during play through the BONUS drill mechanic, and two distinct free spins modes offer different paths to a big payout.
What drives the game?
The dwarf's drilling machine sits at the centre of the screen and can expand at any point. Special crystals charge it up, allowing it to cover more reels and push the ways-to-win count from the base 1,024 all the way to 16,807. The wider the machine, the more combinations fire on every spin.
A collections mechanic runs alongside this: gather crystals of a specific colour across several spins and they unlock Collection Free Spins — a mode featuring super-symbols that pay significantly more than their standard counterparts.
Where does the real win come from?
Dwarf Mine offers two routes into the bonus. The first: three BONUS drill symbols trigger standard free spins, where the machine keeps expanding and crystals keep accumulating. The second: a completed crystal collection unlocks Collection Free Spins, where super-symbols appear across the reels with elevated payouts on all active ways.
💡 Collection Free Spins — the more valuable bonus
Super-symbols in Collection Free Spins pay noticeably more than standard ones — this mode carries the highest potential for a meaningful run. Standard drill-triggered free spins are solid, but Collection Free Spins sit a level above in terms of possible payouts.
A fully expanded machine combined with active super-symbols during Collection Free Spins is the combination that pushes winnings toward the €488,000 ceiling.
Medium-high volatility — what should you expect?
Dwarf Mine strikes a pleasing balance: the expanding machine and constantly accumulating crystals keep the base game from going quiet. At the same time, medium-high variance means the truly significant runs happen in the bonus modes rather than the base game. The RTP of 96.8% is the strongest figure of any Yggdrasil slot in this review.
⚠️ Check the RTP at your casino
The base RTP is 96.8%, but casinos may offer reduced-return versions. Always check the in-game info screen before placing your first bet.

Frequently asked questions about Dwarf Mine
What's the difference between the two Free Spins modes in Dwarf Mine?
The first one is the regular Free Spins feature, triggered by landing three Drill symbols. During these spins, the machine keeps expanding and crystals continue to build up. The second is Collection Free Spins, unlocked after completing the crystal collection. This mode introduces Super Symbols with bigger payouts, making it the place where the slot's biggest win potential really comes to life.
What does it mean when the game expands, and why does it matter?
The game starts with 1,024 ways to win, which is already pretty good. As you collect crystals, the machine literally grows larger, increasing the number of winning ways all the way up to 16,807. The bigger the game area becomes, the more winning combinations you can land on every spin and the better your chances of hitting a nice payout.
What is Dwarf Mine's RTP, and why is it important?
The RTP is 96.8%, which is one of the highest among Yggdrasil slots. In simple terms, it means the slot returns more money to players over time than many similar games. Of course, RTP works over the long run, but if you're choosing between two similar slots, it's usually worth picking the one with the higher RTP.
