When you use a hint, it will show you the first two moves of the level. If you use a second hint, it will show you the next two moves. Additional hints will show the next two moves. Even if you have already collected most of the paintings on a level, the hint system will use that order, showing you steps you have already completed. If you use a hint and fail a level later, the hint arrows you have unlocked will still appear during your next attempt. If you have multiple hints active on a single level, the next set of arrows you should follow will be highlighted in yellow. Hints are dark green as they are drawn, then fade to light green until they are the active hint before turning yellow.
