FAQ
- How often do ads appear?
- No ads appear during your first 10 minutes of play. After that, at most one ad every 10 minutes. Ads never interrupt a stage; they appear after you clear one.
- Do hints show ads?
- The first time you use a hint on a stage, you can choose to watch a video ad. After watching, hints are unlimited on that stage.
- Can I remove ads?
- Yes. The "Remove Ads" one-time purchase stops the 10-minute ads and lets you use hints without watching ads.
- I got a new iPhone. How do I get my purchases back?
- Install the app with the same Apple ID and tap "Restore Purchases" on the Settings screen.
- Can I transfer my progress?
- Your progress (cleared stages, coins, and so on) is saved only on your device. If you delete the app, your progress is deleted too.
- Which languages are supported?
- Japanese, English, Traditional Chinese, Korean, German, French, and Spanish.
