Mr Green Casino currently has the latest Yggdrasil online slot Dwarf Mine as an exclusive release at their casino, with the official release date of the 21st of March so you will be waiting a few more days before it’s playable at any other casinos.
Dwarf Mine starts with a regular 5×4 reel layout in the base game and uses a “pay anyway” payline format and starts with 1024 ways to win, during the gameplay however additional rows can be mined beneath this slot when the special Bonus Symbol lands in view expanding up to 3 extra rows, and this, in turn, increases the paylines up to a massive 16807 ways to win.
To the left of this slot are 4 different gem collection meters, when these are filled up you are granted a special Collection Free Spins round with some much higher paying symbols based on your average bet size before triggering the feature.
The special collection gems themselves can only be mined from the extra rows that appear when the scatter lands in view, so even if you don’t get 3 scatters the expanding rows are key to triggering these special free spin modes.
The regular free spins are triggered by landing 3 scatters, this can be from a single base game spin, or from revealing additional scatters during the mining process, so for example 2 scatters would reveal 2 extra rows, and contained in these rows could be the 3rd scatter for a full bonus trigger.
The base gameplay is fairly solid with 5 different free spins modes although they all do play out in a similar fashion and there is always something close to being triggered which adds to the excitement and anticipation.
Apart from the different free spins modes, there are no additional random features that can occur and a distinct lack of wild symbols to help with winning combinations.
