There’s a suitably epic feel to the design here. Set against a wintry backdrop, the 7x7 grid of reels are made up of 4 lower value rune stones and 4 higher value stone carvings. The best of these is the Thor’s hammer. Winning combinations are created by landing clusters of matching symbols.
You need to land 5 or more to land a winner. Land 40 of the top paying hammer and you’ll receive a payout of 25 times your stake. There’s also a wild which replaces all paying symbols. Red Tiger Gaming has packed in a good selection of extras here:
- Lightning Strikes feature - on any spin, the animated Thor can summon up a lightning strike. This can remove lower value symbols from the reels or turn a random selection of symbols into the same one (or better still a wild).
- Hammer Strike feature - Thor can throw his hammer onto the reels on any spin. This could lead to a nudge or symbol removal which leads to a new winning combination being created.
In the centre of the reels you’ll see a 9-symbol free spins block. These symbols are locked. Land a winner adjacent to a symbol and it unlocks. Unlock all the blocks in the same set of symbol drop sequences and you’ll trigger 1 of 2 free spin rounds:
- Valhalla Free Spins feature - here the reels are made up entirely of blanks and golden shield symbols. Once all your free spins are completed, all the shields on view are flipped round to reveal a stake multiplier. These are added together to give you your total payout amount.
- Muspell Free Spins feature - these take place on a new set of reels where all of the lower value symbols have been removed. The symbol drops are in play here too. The Lava Shower feature also applies randomly to destroy 1 or more type of symbols for a free respin. The Lava Flow feature creates identical symbols on connected reels for guaranteed wins.
We really liked Thor’s Lightning. The imagery is superbly drawn and there’s a sweeping orchestral score to accompany the action. The gameplay matches the high-class sound and visuals too. The hammer and lightning strikes pep up the base game.
It’s the free spins features where the best winning potential arises though. That’s especially the case with the Muspell Free Spins feature. We managed to win over 1,000 times our stakes after getting on a good run with the chain reaction wins.
We’ve seen more volatile Norse-themed slots than Thor’s Lightning (I’m referring to NetEnt’s Vikings) but the combination of quality design and playable features make this a very entertaining game. You can win up to 1,800 times your stake on every spin too which helps.
