As usual for an Yggdrasil Gaming slot game, the design here is very high end. The setting is a mine shaft. Perched to the right of the reels is a dwarf miner who pulls a lever to trigger each spin. The reels feature lower value playing card suit symbols as well as shovels, lamps, pick axes and a miner’s helmet.
Most of the action takes place on a 5 reel, 4 row machine. Look out for the Bonus symbol on the middle 3 reels. When one of these hits, the reels expand by 1 row, up to a maximum of 3 rows. The number of ways increases up to 16,897 – this is called the Expanding Reels feature.
4 higher value gemstone symbols can appear on the expanded portion of the reels only. Every time 1 of these hits, it is collected in a meter to the left of the reels. Once you have amassed 5 of any 1 colour, you’ll trigger 1 of the game’s features.
Collection Free Spins feature - once triggered, you’ll receive 5 free spins. These are played out on a fully expanded 5 reel, 7 row machine. Also joining the action here are 1 of a quartet of Super High Pay symbols. The best of these is the red triangle which awards 4 times your stake if you land 5 in combination.
Free Spins feature - this round is triggered by landing 3 of the Bonus symbol on the same spin. On offer here are 10 free spins. These too are played on the fully expanded reels which offer the maximum 16,807 ways to win. You’ll only see the standard symbols here though, not the Super High Payers.
This mining-themed slot game is an enjoyable one. The visuals are terrifically well done and the stirring soundtracks fits the theme rather well. The gameplay offers something a little different too, especially for an Yggdrasil Gaming slot game. The game isn’t overloaded with extras though. If you want plenty of variety, then you might be better served looking elsewhere.
Expanding reel slot games are all the rage at the moment. This is another impressive addition. Well designed and offering enough action to keep things interesting, there could be treasure lurking in the Dwarf Mine if fortune is with you. You can win a cool 3,904.2 times your stake on every free spin if you’re lucky. If you like the theme, Dwarfs Gone Wild from Quickspin is virtually the same.
