The first thing you should do is adjust your bet. You can choose between 10c and $100 per spin, which is enough for most players. As a slot with 729 ways to win, you can expect to hit a win by landing three or more matching symbols on adjacent reels instead of lines. As the name suggests, the main features are linked to the three different types of wilds.
Which one you meet first is completely random. The regular wild does what a wild does, so it substitutes for other symbols in winning combinations. Then you have countdown wilds in the form of Thor and Loki, which land on reels 3 and 4 only. When they’re part of a win, they trigger countdown responses. You can earn 2, 3, or 4, depending on the number that appears on them. A wild combo feature occurs if you score a win with 1-2 countdown wilds and when both multiplier wilds are active.
The multiplier wild feature is active at all points of the game. If the ravens land on their respective reels (2 and 5) and are part of a win, they trigger wild respins and turn sticky. Each consecutive win increases the progressive wild multiplier by x1. As long as the ravens create winning combination, the respins will continue and the multiplier value will rise with no end in sight.
