The Witches Bonus in Witch Pickings is triggered by landing of three or more Scatter Symbols across the reels. When this occurs, you will pick up five free games as a reward. From this point, you will need to choose from the three different parts of the game. The first comes from the Blue Witch, who can turn a random symbol into a selected symbol. Any time the selected symbol lands on the reels, it can award a prize of 25, 50, 100, 150, 200, 250, or 500. The prizes are then multiplied by your bet.
Next up is the Red Witch. She can take any Wild Symbols that land during the Bonus Feature and expand them to cover three positions on the reels at any one time. On top of this, any win involving a Wild Symbol can be multiplied by 2, 3, 4, 5, or 10. Finally, there is the Green Witch, who can add five free games onto the bonus while multiplying any wins by 2, 3, 4, or 5.
