The low-value symbols are the four runes. There are also four stone carvings with Thor’s hammer being the best paying one. Depending on how many of them you land as a part of a cluster, you can win up to 25 times your stake.
Thor himself is the wild symbol in the game and it substitutes all the other symbols to create a winning combo. There is no scatter symbol. When you get the reels spinning you will see that the symbols that form winning combinations explode and they are replaced by new ones, which gives you the chance to score unlimited wins.
Thor’s Lightning Bonus Features
There are two features triggered at random during the base game
Hammer Strike – Thor smashes 2×2 symbol blocks on the grid and they are substituted by premium symbols
Lightning Strike – Thor shoots lightning bolts to remove the low-value symbols and turn them into matching ones
Thor’s Lightning Free Spins
The free spins features are triggered when you break the 9 inactive tiles in the middle of the grid. Then, either the Valhalla Free Spins or the Muspell Free Spins are activated.
If you trigger the Valhalla Free Spins, you will play on a blank grid. Gold symbols will drop onto the grid but they will remain locked. When all free spins are used, the locked symbols reveal multipliers that determine your total win.
If you trigger the Muspell Free Spins, all low-value symbols will be removed from the grid. During the Muspell Free Spins, you may also trigger the Lava Shower feature or the Lava Flow feature. The lava destroys symbols and adds new premium ones.
Bottom Line
Our only criticism is that Red Tiger could have bumped slot’s winning potential a little bit. You can win 1800 times your stake, which makes us think that Thor’s Lightning is tailored to entertain the masses. It has a small max bet size but the fantastic visuals and the in-game features will keep you on your toes, so, give it a try and prepare for an action-packed gambling session.
