This slot is themed on Nordic mythology.
Players will find themselves suspended in a stormy sky facing iron reels. They’ll gather mystical symbols wrought in glinting metal for a chance at entry into Valhalla.
The atmosphere is ominous and epic. Players will feel they’ve entered a Scandanavian adventure as lightning bolts strike and they hope the gods are on their side.
The soundtrack will bring to mind shows such as Game of Thrones and Vikings. The moody violin sequences set a dark tone and don’t distract from the gameplay.
The Norse symbols are thoughtfully designed. Trees and animals are animated with striking, rune-like lines. Upon wins the symbols glow blue as if struck by lightning.
The animation colour palette is restrained with mostly blues and greys. This makes the hints of colour in the symbols and the bright blue lightning stand out.
Softly glowing flames stand either side of the reels and provide a ceremonial atmosphere. This makes the game feel more like an enchanted trial.
Though Thor is depicted among the symbols, he is otherwise quite absent from the game. Given that he is the slot’s namesake this is a missed opportunity. Thor is a compelling figure who could have been used more prominently to add tension and cachet.
The backdrop of snowy mountains and cloudy sky creates a sense of tension. Players will feel they are high above the landscape as they face their mythical challenge.
Thor's Vengeance has six reels with the symbols in a pattern of 4-4-3-3-4-4.
The gameplay does not feel particularly fast paced and players who are accustomed to other slots may grow slightly weary after a while.
The Wild symbol substitutes for all paying symbols.
Players achieve wins by landing matching symbols on adjacent reels from left to right. This is known as the Any Way Wins system.
Free Spins are triggered by landing three or more Free Spins symbols landing anywhere on the reels.
A Growing Multiplier increases throughout the Free Spins and remains for the whole feature.
Thor’s Lightning feature can remove every low paying symbol or exchange symbols of the same kind at random or transform them to Wilds (this will prompt guaranteed wins).
Thor’s Hammer feature can add a 2x2 Wild or prompt a nudge on the reels for guaranteed wins.
The return to player of this game is 95.66%, below our yardstick for average of roughly 96%.
The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.20 up to a maximum of $/£/€10.00 per spin.
The volatility of this game is medium, which makes it a less ideal match for our preferred slot machine strategies. Our slot strategies target the highest possible volatility.
We do not recommend this low RTP, medium volatility Norse mythology-themed slot.
The well executed theme and high quality animation do not overcome this game’s poor strategy profile. Perhaps the most fervent mythology fans will drop by this game, but to maximise their wins they’ll move along promptly.
The gameplay and bonuses are acceptable, but do not bring enough allure to draw in discerning players.
