Dwarf Mine Slot Review
Down a mine shaft hewn from dark rock, a red-bearded dwarf in a miner’s helmet grips the handle of a huge iron winch, and the reels sit framed in bolted timber with steel pistons bracing the corners. It’s a warm, hand-painted picture, and Dwarf Mine uses it well: this is one of the rare expanding-reels slots where growth actually matters. The three extra rows are the only place Collectible Crystals can land, and crystals are the only route to the game’s best-paying round.
Most games in this family expand the reels and hope that’s enough. This one makes you need it. Yggdrasil built it on a 5×4 grid with low volatility, a 96.8% RTP and a hit rate of 20.67%, meaning roughly one spin in five connects. The ceiling sits at 3,905x the stake. Stakes run from 0.10 to 125 per spin, and the studio’s catalogue neighbours like Badger Miners and Multifly cover similar ground.
Base Game & Features
The base game runs on five reels and four rows, paying across 1,024 ways. Wins form when the same symbol lands on three consecutive reels from the left, and any reel carrying more than one copy of that symbol multiplies the win. Two symbols on the first reel, three on the second and two on the third multiply together for a 12x win. There’s no wild in this game; the Bonus Symbol is the only special that lands.
Working out a ways win runs in three steps:
- Count the consecutive reels holding the symbol, starting from the leftmost reel.
- Three or more (two or more for super high paying symbols) takes the value from the paytable.
- Multiply the number of symbols on each winning reel together, then sum every separate way win for the spin.
The stacking multiplier is where the big base-game wins hide. A five-of-a-kind with one symbol on each reel pays the paytable figure; the same win with two symbols on every reel is multiplied by 32, and heavier stacks push that further.
The paytable splits into four regular high-pay symbols, represented by dwarven tools, four low-pay card suits and four gems in between. Gem values at the default 2.50 stake:
- Red Gem – 4.00 for two, 8.00 for three, 9.60 for four, 16.00 for five
- Blue Gem – 4.00, 7.20, 8.80, 14.40
- Gold Gem – 4.00, 6.40, 8.00, 12.80
- Green Gem – 4.00, 5.60, 7.20, 11.20
Every gem pays the same 4.00 for a pair, so the gaps only open up from three of a kind onward. The bet is always 25 coins per spin, with the coin denomination doing the adjusting – the stake range is really a coin-value range.
Coin values below one cent exist in some currencies, and cash prizes there round to the nearest full cent. Exact half-cent amounts round to the closest even value, so a 2.5 cent win pays 2 cents.
Expanding Reels
Each Bonus Symbol that lands expands the reels by one row for that spin, and the grid can grow by up to three rows in total. Bonus Symbols only appear in the base game, and only on reels one, three and five, which caps the expansion at three per spin. The symbols filling the new bottom rows are placed at random, so an expansion doesn’t guarantee anything – it just widens the dig.
The payline count climbs as the rows do:
- 5×4 reels – 1,024 ways
- 5×5 reels – 3,125 ways
- 5×6 reels – 7,776 ways
- 5×7 reels – 16,807 ways
Those expanded rows matter for more than ways, though, because they’re the only place Collectible Crystals can appear.
Dwarf Mine Free Spins & Collections
Two separate bonus rounds live in this game, and both run on the fully expanded 5×7 reel set. What triggers each one:
- Three Bonus Symbols in one spin – 10 Regular Free Spins
- Five identical Collectible Crystals collected – 5 Collection Free Spins
Free Spins
Landing three Bonus Symbols awards 10 Free Spins, played on the full 5×7 reel set – all 16,807 ways, from the first spin. The round carries the same bet as the activating spin. No Bonus Symbols or Collectible Crystals appear inside it, so the reels stay at maximum size throughout.
Collectible Crystals & Collection Free Spins
Collectible Crystals land only on the three expanded rows in the base game, in green, yellow, blue and red. Collecting five of any one colour awards 5 Collection Free Spins. Each crystal can only land once per spin, so a collection is a genuine grind rather than a lucky spin’s work.
Progress boxes beside the reels track each colour’s tally throughout the base game, so the build is always visible. New players start with three red crystals already banked, a small head start on the red collection.
If two collections complete on the same spin, they pay out in green, yellow, blue, red order. If a collection and regular Free Spins both trigger at once, the regular round goes first.
Collection Free Spins add a Super High Paying Symbol matching the colour of the completed collection to every reel set. These supers pay from just two consecutive reels, which is a shorter road to a win than anything else in the game manages. The four super symbols exist only inside this round – they never touch the base game.
One wrinkle worth knowing: Collection Free Spins are played at the average bet value across every spin that went into the collection. Mix your stakes while collecting and the round pays at that blended level, not at whatever you were betting when the fifth crystal dropped.
Our Honest Verdict
Overall Rating: 7.7/10
This is a slow, deliberate game, and the reason to choose it is the collection meters ticking up beside the reels – the dwarf’s dig pays off in inches, and the design makes you enjoy watching them happen. Regular Free Spins arrive along the way, but they’re the pit stop, not the seam.
The collection round is the best thing here. Five spins sounds stingy until you notice the supers pay from two reels, which turns every spin of that round into several chances at once. The cost of that design is the wait: crystals only land on expanded rows, so the game you’re actually playing most of the time is a low-volatility grind with modest pays and no wild to liven it up.
It suits the patient – players who like a visible, honest build towards a named reward. Anyone after a single swing that changes the session won’t find it down here. The vein is real, but it yields to a steady hand on the winch.
