As a mage-in-training, you've accidentally converted a patch of harmless pumpkins into evil magical jack-o-lanterns.
Convert them back into harmless pumpkins in as few moves, and as quickly, as possible - before things get even more out of hand.
Solve the puzzle by exercising your logic and deductive skills. Choose level 3 for a quick game for all age groups. Level 4 requires a bit more time - at least for me.
