Dwarf Mine Pros and Cons

Reviewed by Paul Stone
Published: September 2018

Pros

• The expanding-reel hook is genuinely satisfying: every drill bonus symbol digs an extra row into the grid, and watching the board grow from 1,024 toward 16,807 ways builds visible momentum no payline counter can match.
• At 96.80% the RTP runs notably above Yggdrasil’s own house standard of 96.10%, so the long-term return here is better than most of the studio’s catalogue.
• The per-reel multiplier is the quiet star, when two or more matching symbols stack on a single reel a multiplier is applied, and on a fully dug 7-row grid this is where the slot’s biggest hits actually come from.
• Two distinct free-spin modes keep the bonus varied: the standard 10 spins play on the full 16,807-way board, while the Collection round swaps in super-high-value gem symbols you have stockpiled.

Cons

• There is no wild symbol at all, Yggdrasil left it out by design, so there is no substitute to rescue near-misses, and runs can feel dry when the drill symbols stay away.
• The 3,904x stake max win is modest, and combined with medium volatility the slot simply does not have the ceiling that 16,807 ways might lead you to expect.
• The standard free spins do not retrigger, so the headline bonus is a fixed 10 spins with no way to extend it, the round can end just as the big board gets going.
• Operators can run lower variable RTP versions, so the strong 96.80% figure is not guaranteed everywhere, check the in-game info screen first.

How Dwarf Mine Works

Dwarf Mine starts as a 5-reel, 4-row slot with 1,024 ways to win, paying for matching symbols on adjacent reels from the left, there are no fixed paylines. The drill-machine bonus symbol lands only on reels 1, 3 and 5, and each one permanently expands its reel downward by one row for that spin. Stack up to three extra rows and the whole grid becomes 5×7, opening the full 16,807 ways to win. Land three drill symbols together on reels 1, 3 and 5 and you also trigger the free spins on that fully expanded board.

Symbols and Paytable

There is no wild in Dwarf Mine. Low symbols are the four card suits; the premium set is dwarven mining gear, shovel, pick, helmet and the lantern, which is the top regular symbol at around 1.4x stake for a full way. A third set of coloured gemstones (red, blue, orange and green) appears only on the three expandable reels and is collected toward the Collection bonus. The per-reel multiplier, applied when more than one matching symbol lands on a reel, is what turns the modest base pays into real wins on a tall grid.

Dwarf Mine Features

Expanding Reels

The defining mechanic. Each drill bonus symbol on reels 1, 3 or 5 cranks that reel one row taller, up to three extra rows. A single expansion is common and keeps something happening every few spins; a full three-row dig to the 5×7, 16,807-way board is the moment you feel a big win could land, because every extra row multiplies the ways exponentially.

Standard Free Spins

Land three drill symbols on reels 1, 3 and 5 at once and you win 10 free spins played entirely on the fully expanded 16,807-way grid. There are no retriggers, so it is a fixed burst, but with the board at maximum height and the per-reel multipliers active, it is where most of the slot’s larger payouts occur.

Collection Free Spins

Coloured gems collect on the expandable reels during the base game; gather five of one colour and you trigger the Collection Free Spins, five spins on the 5×7 board where Super High symbols replace the standard gems. It is a slower-burning route to a bonus that rewards patient base-game play rather than a lucky drill landing.

DWARFS GONE WILD: – Quickspin’s dwarf slot runs 20 lines with Throwback and Spreading Wilds plus win multipliers at medium volatility. Unlike Dwarf Mine it leans heavily on wild features rather than a growing grid, so it is the wild-focused alternative.

DWARVEN GOLD DELUXE: – Pragmatic Play’s 25-line dwarf slot keeps things classic with scatters, free spins and expanding wilds at medium-low volatility. It is a simpler, more traditional take for players who find Dwarf Mine’s expanding grid too busy.

7 LUCKY DWARFS: – Leander Games’ dwarf slot packs in a Dig Dig mine round, a Mirror feature and free spins across 20 lines. It is the closest themed cousin to Dwarf Mine, sharing the underground-mining hook with a more feature-driven base game.

PINK ELEPHANTS: – Thunderkick’s high-volatility hit runs 4,096 ways with mystery symbols and a collect-to-trigger free spins round. It shares the multi-way, collection-style design philosophy with Dwarf Mine but swings far harder.

Our favourite Dwarf slots

Dwarf Mine is a mining-and-treasure slot built around a single comic touch: a bearded, Irish-looking dwarf operating a hydraulic digging rig that physically extends the reels downward as you play. The backdrop hides buried skeletons, dinosaur bones and a leprechaun hat in the bedrock, which gives the cartoon art real character. If you like slots like Dwarf Mine for the dwarf-and-gems theme, the titles below, 7 Lucky Dwarfs, Dwarven Gold Deluxe and Dwarfs Gone Wild, share the setting, though none expand the grid the way Dwarf Mine does.

Dwarf Mine FAQs

What is the maximum win on Dwarf Mine?

The Dwarf Mine max win is around 3,904x your stake. It is modest given the 16,807 ways on offer, a result of the medium volatility and the lack of a wild symbol.

How does the expanding reels feature work?

Drill bonus symbols on reels 1, 3 and 5 each add one row to their reel, up to three extra rows. A fully expanded grid becomes 5×7 with 16,807 ways to win instead of the starting 1,024.

Does Dwarf Mine have a wild symbol?

No. Yggdrasil deliberately left the wild out of Dwarf Mine. The win potential instead comes from the expanding reels and the per-reel multiplier applied when matching symbols stack on a reel.

How do you trigger free spins in Dwarf Mine?

Land three drill bonus symbols on reels 1, 3 and 5 in the same spin to win 10 free spins on the full 16,807-way grid. Collecting five gems of one colour separately triggers the Collection Free Spins.

Our Verdict on Dwarf Mine

Dwarf Mine is one of Yggdrasil’s most quietly clever slots: the dig-the-grid mechanic is genuinely novel, the production is sharp, and a 96.80% RTP is well above the studio norm. It is held back by a modest 3,904x ceiling, medium volatility and the deliberate absence of a wild, so it suits players who enjoy a mechanic-led, steady grind over those chasing a big payout. If you like slots like Dwarf Mine, Pink Elephants offers a punchier collection-and-multiway design, while 7 Lucky Dwarfs and Dwarven Gold Deluxe keep the same mining theme with more conventional maths.
