Thor’s Lightning slot review

Norse mythology has featured in quite a number of online slots lately, but that doesn’t mean that there’s no more potential for originality – Red Tiger’s new game, Thor’s Lightning, is one such example. This game will immediately impress you with its exceptional graphics and originality of features, which include two base game features and two free spins modes. Our review of Thor’s Lightning slot below will help you understand how it all works so you'll know what to expect before you give it a spin.

Thor’s Lightning slot features

Thor’s Lightning is played out on a 7x7 grid, where symbols drop from the top each time you spin. Wins are formed by landing a cluster of 6 or more like symbols; as is the usual case with cluster pays slots, these winning symbols explode and get replaced by new ones, allowing you to form consecutive wins following the same spin. Symbols include 4 low-paying rune stones and 4 higher-value stone carvings, amongst them Thor’s hammer. There’s also a wild symbol which replaces all other symbols, as well as a couple of cool base game features:

Lightning Strikes feature – this is when Thor summons up the lightning! This will remove lower value symbols from the grid and turn a random selection of symbols into identical symbols, which could even be a wild!

Hammer Strike feature – Thor will throw his hammer onto the reels on any random spin. This will nudge or remove a symbol to help create a new winning combination.

Thors Lightning slot free spins

Right in the middle of the reels in Thor’s Lightning slot, you’ll notice a free spins block made up of 9 symbols. These symbols are greyed out before every spin, and will be unlocked if you form a win adjacent to them. The key to triggering the free spins is to land wins on all four sides of this block thanks to consecutive wins. If you do this, you’ll get to one of 2 free spins features:

Valhalla Free Spins – the reels will only contain blanks and golden shields that are locked into place once they land. Once the free spins are completed, all the shields that land during the round will flip around to reveal a multiplier! The multipliers are then added together to give you a massive win!

Muspell Free Spins – these spins will take place on a new reel set containing only high value symbols. A Lava feature can also come into play here to destroy one or more type of symbols and give you a respin, whereas the Lava Flow feature will create identical symbols on connected reels and guarantee you a win!

Thor’s Lightning slot min/max bets, RTP, volatility and maximum win

As from the 14th of February, Thor’s Lightning slot should be available at a number of Red Tiger casinos, and you’ll be able to play it by staking between 20p and £40 on each spin. The RTP is set to 96.08% and volatility is in the high end of the spectrum, though you’ll still enjoy a pretty good hit frequency, especially when it comes to the base game features. However, keep in mind that landing consecutive wins doesn’t always mean that you’ll win more than you originally staked, and that the best wins are to be had from the free spins features, where you can win up to 1,8000 times your stake on each free spin.
