The leading software supplier Microgaming was the first to introduce the 243 ways to win system that eliminates the traditional payline concept. In slots like Cool Wolf, there are no paylines and winning combinations are created by a certain number of identical symbols (mainly three and greater) that fall on adjacent reels starting from the leftmost reel. So the player is not required to land relevant symbols on a preset payline pattern to get a coin award. In Cool Wolf, the minimum bet is $0.5, while the maximum amount you can wager is $50 per spin.

The slot is themed about a geek teenager who lives in Howlingwood and transforms into a werewolf at night and the symbols are designed to outline a short story of a shy guy who studies at day and turns into a wolf when night comes. Then he picks up a girl or two, turns on the engine of his hot rod and rides the highway all night long.

Standard playing cards are the lowest-paying icons that award 2 to 125 coins for 3+ of a kind. Themed symbols are mid-paying ones and award 12 to 500 coins for three, four or five of them landed on adjacent reels left to right. The highest potential win for the game is $5000 when you hit five scatter symbols in any position.

Bonus features

The developer has equipped the slot with the branded Rolling Reels feature. On every winning combination, the symbols that make part of it disappear and the remaining symbols fall from above to fill in the spaces, which can result in one or more new winning combos. The feature continues until no more combinations are created. During the free spins, which are triggered by 3–5 scatters, the Rolling Reels feature is complemented by multipliers that go up from x2 to x10 on every consecutive win.

Added for bigger prizes is a wild symbol (slot logo) that comes stacked on reels 3, 4 and 5 in base game and in free spins. Besides, any random spin can end up with the Howling Wild feature. Added for bigger rewards, it turns an entire reel into wild for a guaranteed win.
