Dwarf Mine

Dwarf Mine heads down a mine shaft with a miner standing guard beside the reels in this Yggdrasil slot. Gems, helmets, axes, lamps and shovels are the premium finds, and the grid starts at 1024 ways on 5 reels but can grow to 16807 ways when it expands to seven rows.

The drill bonus symbol does the digging: each one that lands adds a row, up to three extra, and three of them award 10 free spins on the fully expanded 5x7 grid. While the reels are expanded, coloured gems can be collected, and five of one colour unlock 5 collection free spins with super high-paying symbols. A 96.8 % RTP, medium volatility and stakes from 0.1 € to 200 € make it one of the higher-return titles in this folder.

Matching symbols on consecutive reels pay, and some pay from two of a kind. The red gem is the top symbol at 100 coins for five, the other mining symbols start at 10 coins for three, and hearts, diamonds, spades and clubs pay 5 to 15 coins.
