Answers to common questions about saving progress, hearts, hints and mobile controls.
Where is my progress saved?
Complete a level to unlock the next. Cleared levels stay available to replay. Your progress, hint balance and audio preferences are stored in this browser, not a cloud account. Clearing site data, using private browsing or switching devices may reset or separate your progress.
How do hints work?
You start with three hints. Each hint highlights an arrow with a clear exit. Hints do not refill when you restart or change levels. If rewarded advertising is enabled and an ad is available, completing the optional ad earns one hint. Skipped or failed ads grant no hint.
Why did I lose a heart?
An arrow exits in the direction of its tip. Its straight exit lane must be clear of every other arrow, including their tails. Tapping a blocked arrow costs one of your five hearts. Clear the whole board to complete the level; if you lose all hearts, restart and try a different order.
Can I play on my phone?
Tap an arrow on a phone or click it on a computer. Pinch or use the zoom controls to inspect dense puzzles, then drag to explore. The grid helps you align lanes. Music and effects have separate controls. Fullscreen requires a tap and depends on browser support.
