When Thor's hammer was summoned to action, a hero's soundtrack and a completely dramatic blow made the stunning slot creation. As usual, the Red Tiger game is performing a perfect theme to the smallest details. In this game it extends to nine regular paying symbols on the reels. There are four smaller runes at the low end, followed by four Nordic combat masks and a Thor hammer.
Instead, the symbols fall on a 7x7 grid in a cascade. Cancel the winning combination and the new symbol is in place. This situation continued until there was no new victory after the fresh decline. Unlocking the center portion of the nine symbols in a sequence will trigger a free spin.
