All the time that you are playing this slot, the sound effects will have you believing that you are in the middle of a horrendous storm and are tucked up in some shelter on Scandinavian tundra, waiting out the storm. The Thunderstruck slot is based on the Norse legends of a god of thunder named Thor who had the ability to create storms on a whim. The Vikings, as part of their preparations for long voyages, would sacrifice a ram in Thor’s name in the hope of appeasing him so that he would start no storm whilst they were at sea.

To coincide with the theme, both symbols representing Thor and symbols representing rams appear on the reels and it is the Thor symbol which is the wild and can replace any other symbol with the exception of the rams’ symbol which is the scatter. By taking the place of some of the other symbols, the wild symbol is able to create winning combinations which otherwise wouldn’t have been. This ensures a steady succession of wins as you play but not only that, when the wild symbol is used in a winning combination, that win is doubled in its value.

The scatter symbol can earn you a win anytime 2 of them appear anywhere in view on the reels but perhaps more importantly, if at least 3 of them appear at the same time, they will trigger the bonus round. The bonus round on this slot is a free spin round which means that anytime that it is triggered, it awards the player 12 free spins with which they can try and win as much as possible without having to use another coin. To some, 12 free spins may seem generous enough but to others it may seem a little mean and so, as Thor apparently does like rams, the round is allowed to be retriggered which means every time that 3 or more rams appear on the reels, 12 more free spins will be added to any that are still left from the last time the round was triggered.
