Witch Heart wild symbols can appear on reels 2-6, contributing to a winning line up to three times in a single tumble sequence. After the third win, the wild symbol explodes, awarding 2-9 more wilds in random positions across the grid.

3, 4, 5, or 6 bonus symbols trigger the feature with 10, 15, 20, or 30 free spins. The bonus game begins with a 1x win multiplier, which increases by 1x with every tumble. Witch Heart wilds can also increase the multiplier – by 6x if one wild explodes, 13x for two wilds exploding simultaneously, and 20x if three wilds explode at the same time.
