Totem Tower Bonanza

Wild symbols come in 3 tiers (Basic, Rare, Epic), each with a tier-based multiplier. They substitute for any paying symbol and, when part of a win, their multipliers are added together and applied to the payline.
In Bonus Game 1 Wild symbols become sticky.
In Bonus 2 and Bonus 3 games Wilds can also expand into Wild Reels. If multiple Wilds land on the same reel, their multipliers multiply together to create one Wild Reel multiplier. When multiple Wild Reels participate in a win, their multipliers are added together.
