Thor, Yggdrasil and multipliers in Gemhalla
In the Gemhalla slot, provider BGaming turned to Scandinavian mythology: Thor stands by the Yggdrasil tree, which in the game becomes a source of big wins. The 6-reel grid works on a Pay Anywhere system — payouts are awarded for the total number of matching symbols on screen after a spin. The bet range is from 0.2 to 50, suitable for different budgets.
Refilling, free spins and accumulating multipliers
The key mechanic of Gemhalla is the Refilling feature: after each payout, winning symbols disappear and new ones drop in their place, continuing the chain until there are no more matches. Multiplier symbols appear randomly — from x2 to x500. In the base game their values are summed if several multipliers land in one spin. During free spins, multipliers work differently: they accumulate, and the total sum is applied to the spin's win together with those already collected. 4 or more scatters trigger 15 free spins, re-triggering is possible with 3+ scatters. Also available is a bonus buy for 100x the bet and Chance x2 mode, which increases the bet by 25% to boost the chance of scatters.
Specifications for experienced players
The 97.17% RTP is above the industry average, but high volatility means long stretches without big payouts and sharp balance swings. The maximum x5000 multiplier is achievable through the combination of cascades and accumulating multipliers in free spins. All BGaming slots feature high RTP, and Gemhalla is no exception.
