Dwarf Mine

Dwarf Mine, created by Yggdrasil, is a video slot that begins with a configuration of 5 reels and 4 rows, which can expand to a maximum of 5×7 rows, enhancing the potential winning combinations from 1,024 to 16,807. Set in an underground environment, players will find animals busy searching for sparkling crystals, gemstones, and various mining equipment such as helmets, lanterns, and pickaxes. In the base game, Bonus symbols, depicted as drilling or diamond drill icons, can appear on reels 1, 3, and 5, allowing the reels to expand by one row for each symbol, with a maximum of three expansions possible. When all three Bonus symbols land in a single spin, the Free Spins feature is activated, awarding 10 free spins with the reels already fully expanded. Additionally, the game features a Crystal Collection system: collecting five identical crystals of one color during the base game triggers Collection Free Spins, which offer 5 spins that include super high-paying symbols corresponding to the collected crystal's color. During the Collection Free Spins, standard symbols are replaced by these high-value symbols. Wins are achieved by landing three or more matching symbols on adjacent reels starting from the left, while only two are required for the super high-value symbols. There is no option to buy bonuses in this game.
