Gemhalla by BGaming uses a 6-5 layout with a 97% RTP and high volatility. Minimum bet is 0.1 USD and maximum bet is 100 USD; the hit frequency is 25.64 and the top win is x87.

Additionally, the game includes Bonus Bet, Scatter symbols, Free Spins, Buy Feature, Symbols collection (Energy), RTP range, Random multiplier, Pay Anywhere, Free Spins Multiplier, and Multiplier.

In practice, the visuals draw on helmet, shield, hammer, ships and Viking motifs set in a sky blue and violet palette, with brown and beer accents.

In practice, Free Spins Multiplier and Random multiplier contribute to variability across spins. The overall feature set aligns with a high-variance design, which may lead to infrequent but potentially sizable outcomes.
