Developer Gemhalla is a video slot by BGaming set in Norse mythology, with Thor and the Yggdrasil tree forming the main theme. The game uses a 6x5 layout with pay-anywhere mechanics, where matching symbols are counted across the reels rather than on fixed paylines. Its RTP is 97.17%, and the slot is classed as very high volatility.
During play, multiplier symbols can appear in both the base game and Free Spins, ranging from x2 to x500. If several multipliers land in one spin, their values are combined. The Refilling Reels feature removes winning symbols and drops in new ones, allowing for repeated wins from a single spin until no new combinations are formed. Scatter symbols can appear on any reel, and 4 or more trigger 15 Free Spins, with retriggers available when 3 or more Scatters land during the bonus round.
The game page offers a demo version, allowing players to play for free and practice before playing for real money. Gemhalla also includes options to buy the Free Spins feature or activate Chance x2, which increases the stake and boosts the chance of triggering the bonus round. The maximum win is listed at €250,000, with a top multiplier of x5000.
