Hearts and Hints
How to make the most of your limited resources.
Hearts are your margin for error. You can get blocked up to three times, but if you're aiming for a flawless clear, it's best not to waste even one.
A hint highlights one arrow you can clear right now. Use it as a lifeline when you're completely stuck, but leaning on it every move won't help you improve.
Just get in the habit of checking the path visually before you tap, and you'll rarely need hearts or hints at all.
