About this Slot
Fat Thor is a mythology and fantasy-themed slot by Spinner Labs with an RTP of 96%, high volatility and a maximum win of 50,000x the stake. The game plays across a 7-reel, 5-row grid with cluster pays mechanics, where winning clusters trigger cascades that continue until no fresh wins land.
Land four or more Bonus symbols to trigger the bonus round. Only one Bonus symbol can appear per reel. Silver Wilds substitute for other symbols and collect multipliers during the base game, but retain their collected value only during Free Spins. Golden Wilds land exclusively on reel 3 centre and collect multipliers throughout the entire bonus round.
When a Wild collects a multiplier symbol, it removes that multiplier from the grid and respins its position. Multiplier symbols display values from x2 to x1000.
During Free Spins, landing three or more additional Bonus symbols awards five extra spins. The Valhalla Bonus buy grants 15 Free Spins directly and adds the Golden Wild option to the feature. The Ragnarok Bonus buy also grants 15 Free Spins directly and guarantees a Golden Wild on the first spin, with three or more additional Bonus symbols awarding five extra spins. Ragnarok Bonus is the highest-cost buy option available.
The Stormcall buy increases the frequency of Bonus symbols in the base game. Forge Spin guarantees a minimum of one Wild and two Multipliers per spin.
