How Howling for Gold works

Wins pay on 25 lines across a 5×4 grid. The wild substitutes for everything except the full-moon scatter and also pays on its own. Golden wolf-paw mystery symbols can land in the base game and all turn into the same paying symbol.

Free spins and upgrades

Three, four or five full-moon scatters award 8, 10 or 12 free spins, plus a scatter prize. During the feature, collecting wilds moves you up a five-level upgrade path, turning lower-paying symbols into higher ones. The further you climb, the richer the reels become.

Feature buy

Where allowed, you can buy straight into the free spins at three price levels (100x, 250x or 500x your bet), with higher prices starting further up the upgrade path.
