About this Slot
Thunder of Valhalla is a mythology and fantasy-themed slot from Forgehaven Studio with an RTP of 96.08%, high volatility, and a maximum win of 8,775x. The game features a 6x5 grid with Cluster Pays mechanics.
Winning symbols cascade down the reels, with fresh symbols falling to create chains of consecutive wins. Five Blessed Multipliers are generated per spin. When a Mjölnir symbol lands, it claims a Blessed Multiplier and applies that value to the tumble sequence. Multiple Mjölnir symbols that land consecutively combine their multiplier values before applying the total to the sequence. Once all five Blessed Multipliers are consumed, fresh ones are generated for the next tumble phase.
Four or more Scatter symbols trigger Free Spins, awarding 15 spins to start. During Free Spins, cascading reels continue to apply, with Blessed Multipliers feeding into Mjölnir symbols as normal. Each multiplier value claimed by Mjölnir contributes to a persistent Total Multiplier that carries through the entire Free Spins round. Landing three or more Scatter symbols during Free Spins awards 5 additional spins, and the Total Multiplier persists through any extensions.
The Ante option costs 2x the base bet and increases the chance of triggering Free Spins by 5x. The 50X CHANCE option costs 3x the base bet and guarantees that one Blessed Multiplier will show a value of 50x during the spin. The Avalanche option costs 3x the base bet and increases the likelihood of tumble sequences by 10x. The Instant Bonus option costs 100x the base bet and immediately enters Free Spins with 15 spins.
