Tap a prefecture on the map of Japan to open it, then play its picture puzzles. In a puzzle, drag pieces to swap them and rebuild the original photo before the timer runs out. Clearing stages unlocks new ones, and completing a prefecture earns you a Key to unlock a neighboring region.

You start at Tokyo. Completing every stage of a prefecture awards a 🔑 Key. Spend 1 Key on a neighboring (frontier) prefecture's Unlock button to open it. Prefectures unlock outward from areas you've already cleared.

• 🔑 Key — used only to unlock new prefectures. Earned by completing a prefecture; it cannot be purchased.
• Coin — soft currency earned by clearing stages, your daily login streak, and the free-coin ad. Spent on helper items.
• 💎 Diamond — premium currency available through in-app purchase. Used to buy items or convert into Coins.

• Preview — shows the finished picture so you know what you're building.
• Add Time — adds extra seconds to the puzzle timer.
• Hint — helps you place pieces correctly.

Items are consumable and can be bought in the Shop or in the in-puzzle mini-buy popup.

Once you've cleared every stage in a prefecture, a Replay button appears on cleared stages. Replays run that stage at Super Hard (7×7) for an extra challenge, and pay a small capped Coin reward. Once the entire journey is 100% cleared, Replays step up again to Ultra Hard (8×8).

Most purchases credit automatically — try fully closing and reopening the game, which re-checks for any pending purchase. If your Diamonds still don't appear after a few minutes, email us with your device, the pack you bought, and the approximate purchase time, and we'll help make it right.

Purchases are processed by the Apple App Store or Google Play, so refunds are handled by them — not directly by us.

No. Keys are earned only by completing prefectures and are never sold. Diamonds and Coins can never be exchanged for Keys.

Ads are optional and rewarded — you choose to watch them in exchange for free Coins or extra time. You're never forced to watch an ad to keep playing.

Your progress, wallet, items, and settings are backed up to our servers automatically while you have an internet connection. That backup is what Device Transfer moves, and what protects you if the app itself misbehaves.

Deleting the app is different, and it is the one to be careful about. The key to your backup is kept in the app’s own data, so deleting the app cuts the link to it: the next install starts a new account, and we cannot reach the old save from it. Restoring a whole-device backup (iCloud or Google) does keep your save, because the app’s data comes back with it.

Moving to a new device uses Device Transfer: on the new device open Settings → Game → Device Transfer and scan the QR code shown on your old one. Both devices need to be on hand, and the transfer moves the save rather than copying it — the old device is signed out of that save afterwards.

There is no recovery by code or by email. If you no longer have the old device — or you have already deleted the app from it — we cannot move that save to a new one. Please transfer before you delete the app or part with a phone.

From the map, tap your avatar at the top-left to open your Profile, then tap the gear at the top-right of the Profile screen. There you can switch between English / 日本語 / 中文 and adjust the background music and sound-effect volume.

• Fully close the game and reopen it.
• Make sure your device has the latest OS updates and enough free storage.
• Update to the latest version of the game from the App Store / Google Play.
• Restart your device.
• If the problem continues, email us with your device model and OS version.

Many features need an internet connection (for example, rewarded ads and purchases). Check your connection, then close and reopen the game. If a rewarded ad doesn't load, it may simply be unavailable at that moment — try again later.
