Thor’s Lighting is a 7 reel game that is 7 symbols high. However, there are 9 symbol spaces in the middle of the reels that are inactive and only help to trigger the Free Spins features. The game does not use paylines, instead you win by forming clusters of 5 symbols. Clusters can be formed in vertical and horizonal combinations of identical symbols. Every time you form a winning combination the symbols that made it will disappear, creating a cascade. Symbols will fall into the spaces left by the winning symbols and new symbols will be added to the top of the reels, giving you another chance to win. This will continue until you fail to land a winning combination.

Special Symbols

Wilds – There are two Wild symbols: a red mask and a gold mask. Both operate in the same way, substituting for all paying symbols. They are not worth anything on their own, so have no individual value.

High Paying Symbol – Not including Wilds, the highest paying symbol in the game is the “Golden Hammer” symbol. The “Golden Hammer” symbol return the bet if you form a combination of 5 or 6. It will double the bet if you can form a combination of 7 or 8. It will multiply the bet by 4 in a combination of 9 or 10; multiply the bet by 12 in a combination of 11,12, 13 or 4; multiply the bet by 15 in a combination of 15, 16, 17, 18 or 19. It will multiply the bet by 50 in combination ranging between 20 and 29 matching symbols; 250 in a combination ranging between 30 and 39 symbols and you will multiply the bet by 500 if you can for a combination of 40 or more symbols.

Features

The game comes with a number of features, all of which are triggered at random throughout your spins. Each one is described below:

Lightning – If this feature is randomly triggered then lightning will strike the reels, either replacing all low pay symbols with high paying symbols, or turning randomly selected symbols into the same type or symbols, which could even include wilds.

Hammer – If this feature is randomly triggered then Thor will throw his hammer at the reels and nudge certain rows to ensure that you form winning combinations.

There are two types of Free Spins available: Muspell Spins and Valhalla Spins. You will trigger which ever one is available at the time if you can form winning combinations all the way around the 9 symbols that sit at the centre of the reels. This means that the 8 outer symbols must have winning combinations right next to them before you can trigger the Free Spins.

Muspell Spins – If you trigger the Muspell Free Spins then Thor will remove all low-paying symbols from the reels so only high paying symbols fall on the slot until the end of the feature. Two bonus features are also available during the Muspell Free Spins: Lava Shower and Lava Flow.

Lava Shower – The Lava Shower Bonus is only available during the Muspell Free Spins. If randomly triggered, Lava Showers will hit the reels, destroying symbols and giving you an additional re-spin, during which new symbols will take the place of the destroyed symbols.

Lava Flow – The Lava Flow Bonus is only available on the Muspell Free Spins. If randomly triggered, a flow of lava will move through the reels , creating identical symbols on connected reels.

Valhalla Free Spins – If you trigger the Valhalla Free Spins feature then Thor will remove all the tiles from the game, replacing them with Golden Shields until the feature ends. Golden Shields that land will lock until the end of Free Spins and when the feature ends a multiplier will be revealed on each of the Golden Shields.
