Follow the dwarven digger into a mine with hidden treasures and precious crystals on the first expanding slot from Yggdrasil Gaming. Get ready to see the rows grow from four to seven and ways to win from 1,024 to 16,807 as the dwarf will fire up his digging machine when bonus symbols land on the reels. Collect gems and trigger two types of free spins that can lead to wins of up to 3,904 times your stake.
Dwarf Mine is a video slot with five reels, four rows and 1,024 ways to win in the default setting. This can expand gradually to up to seven rows and 16,807 ways when bonus symbols land on the reels or during the free spins features. Go on a digging tour with the dwarf on desktop or mobile from as little as 0.10 credits up to a maximum of 125 credits. The RTP of this medium to high variance game is set at 96.80%.
You will be descending deep into the ground when you open the game to encounter fossils, lucky Irish hats, empty bottles and ancient stones as well as the red-bearded Irish-looking dwarf. He stands to the right on some sort of digging machine that he will set in motion to expand the reels during the gameplay. Four displays connected to the wooden frame of the game window will indicate your crystal collection progress.
It is all about mining and crystals on this slot. Even the low-value symbols look like the card suits – spades, clubs, hearts and diamonds – have been crafted into crystals. They are followed by shovels, axes, helmets and lanterns at the high end. Hit five across the reels to win 0.75x to 1.75x your stake. A wild symbol is missing while a mining drill acts as the bonus symbol. Watch out for crystals in green, orange, blue and red colours when the game window expands in the main game. They will be collected in the meters on the left. They appear as pay symbol in the free spins only and will award wins of up to 5x your bet for a 5OAK.
You will start your spin with 1,024 ways to win on a 5×4 window. Hitting a bonus symbol will call on the dwarf to start cranking up the rows to five, six or seven for one, two and three scatters respectively. With more rows you will see the ways to win increase from 1,024 to 3,125, 7,776 and 16,807. The game window will reset after spin in the base game but will stay expanded for the duration of the bonus features.
Yggdrasil generously gave the slot not one but two different free spins features. The first is triggered when three scattered drills land anywhere on reels one, three and five in one spin, triggering 10 free spins that will be played on the maximum reel set with seven rows and 16,807 ways to win.
The second are the Collectable Free Spins which are awarded after collecting five crystals of one colour in the base game. You can follow your progress on the meters to the left. You will get five free spins which cannot be retriggered but are played on a different reels set with only the four crystals appearing on the strips. The best moment to hit those monster wins.
Worth the drilling effort or just old fossils buried deep in the ground? Well, I am slightly on the fence about his one. There are no complaints regarding graphics and animations as Yggdrasil always delivers in that respect. Their first foray into megaways games looks certainly good but I was not impressed with the gameplay. Maybe a wild random feature would have spiced up the action sufficiently to make it really suspenseful.
As of now, you have to wait patiently to collect crystals for the higher-value free spins only to see than half-stacks of different crystals landing on the reels which then pay nothing or by far not as much as one would expect after waiting for 200 – 500 spins to complete the collection.
