Welcome to Dwarf Mine Video Slot with Free Spins, Expandable Reels, a Crystal Collection and up to 16,807 Ways to Win.


Dwarf Mine is a Video Slot with 5 reels and 4 rows with the possibility to expand the reels up to 5 reels and 7 rows.

The game has 4 regular high paying symbols, represented by dwarven tools, 4 low pay symbols represented by the 4 card suits and 4 super high paying symbols which only appear in Collection Free Spins. There is also a Bonus symbol which only lands on reels 1, 3 and 5. Finally there are 4 collectible symbols represented by Crystals which only appear on the bottom 3 rows of the expanded reels.

Expanding Reels

Landing a bonus symbol on the reels expands the reels by 1 row down for that spin. Bonus symbols are only present in the base game and only on reels 1, 3, 5. Reels can be expanded a maximum of 3 times since that is also the maximum amount of Bonus symbols that can appear in 1 spin. The symbols on the extended bottom 3 rows are placed randomly.

Free Spin Mode

Landing 3 bonus symbols awards 10 Free Spins with the 5 x 7 reel set. Free Spins do not contain bonus symbols or Collectible Crystals. Free Spins are played with the same bet as the activating spin.

Collectible Crystals

Collecting 5 identical Crystals awarded 5 Collection Free Spins. Collectible Crystals only appear on the expanded rows in the base game. Each Collectible Crystal can only land once each spin. If 2+ collections are complete at the same time, they will be awarded in the following order: green, yellow, blue and red. If collectable Free Spins and regular Free Spins are both triggered at once; regular Free spins activate first. New players are given 3 Red crystals when they play for the first time.

Collection Free Spins

Completing a collection awards 5 Free Spins with the 5 x 7 reel set. These reels do not contain Bonus symbols or Collectible crystals. A Super high paying symbol that is the same color as the collected crystal is added to all reel sets. Collection Free Spins are played with the average coin value of coin values used each spin where the Crystals were collected.


  • Select the coin denomination.
  • Press the Spin button to start game.


  • To calculate the total Ways coin win, add all the symbol wins together.
  • To calculate a single symbol win, count the number of consecutive reels that contain the symbol, starting from the left.
  • If the number of consecutive reels containing the symbol is 3 or greater counting from the left, find the corresponding win amount in the pay table.
  • If any of the reels contain more than 1 instance of the symbols, the win will be multiplied. Multiply the number of symbols on each of the reels to get the final multiplier. For example: if the first reel contain 2 symbols, the second reel has 3 symbols and the third reel has 2 symbols, the total multiplier is counted as follows: 2*3*2=12 (total multiplier).
  • The above doesn't include any Bonus symbols which pay scattered.
  • All Way Wins are summed together after the spin.
  • Calculate the total win in the home currency by multiplying the total coin win with the coin value.


  • This game features coin values of less than 1 cent per coin (in select currencies). When players use a coin value of less than 1 cent per coin, their cash prizes will be rounded to FULL cents in a fair way.
  • The prizes are rounded to the closest FULL cent. 1.4 rounds to 1 and 1.6 rounds to 2.
  • If a win is exactly between two values (e.g 2.5 cents), the rounding goes to the closest EVEN cent (will not round to an ODD amount).
    • 1.5, 3.5, 5.5, 7.5, 9.5 rounds up.
    • 0.5, 2.5, 4.5, 6.5, 8.5 rounds down.
  • Casinos always store balances in cash. When a player chooses ‘coin view’ their cash balance is recalculated into coins.
  • When players choose to display their balance in coins, they will sometimes see a rounding take place when their coin win is added to their balance.
  • For example if they win 21 coins with a coin value of 0.004, their cash win will be 8.4 cents. The cash win is rounded to 8 cents and 20 coins are added to their balance.
