Frequently Asked Questions
Can I move my ranking score to another device?
Open "Ranking" on the title screen, then use the account button at the top right to link your Apple ID or Google account. After a device change or reinstall, sign in with the same account to keep your ranking score. Without linking (anonymous), records stay with each device and cannot be moved. Some data, such as your recent score history, is stored only on the device.
I want to unlink my account
Open "Account" from the Ranking screen and tap "Unlink" next to the linked account to remove the Apple / Google link. "Sign out" returns you to an anonymous state. You can also stop taking part in the ranking from the same screen.
How do I restore purchases?
Tap "Restore Purchases" in the "Shop" on the title screen. "Remove Ads" and "Master Labyrinth" bought before will be restored (the build bought in version 3 or earlier is restored as "Master Labyrinth"). On iOS you need to be signed in with the same Apple ID, and on Android with the same Google account.
If you see "Couldn't restore purchases", check your connection and try again.
How do I hide ads?
Buying the "Remove Ads" in-app purchase removes the banner at the bottom of the screen and the full-screen ad shown after a run.
How do I turn off personalized ads?
Open "Ad settings" on the title screen and choose the non-personalized option. On iOS you can also turn off tracking in Settings → Privacy & Security → Tracking. The game is the same either way.
How do I play?
In each room, pick one of the choices on screen. After each room you see the true odds of every choice and why. You then pick the next room from two paths: the harsh path is harder but scores double. Remember the rooms where your gut and the math disagreed, and your next run gets easier. See "How to Play" on the title screen for details.
How do I quit a run?
Use the "×" at the top left of the room screen (on Android, the back gesture shows the same prompt). A quit run is not saved and is not sent to the ranking. Once your HP reaches 0, you can no longer quit, and the run is recorded.
What is the Daily Labyrinth?
Every day, everyone faces the same rooms. It resets at midnight Japan time (JST). Only your first run of the day goes on the ranking. The run counts as used as soon as you start it, so quitting partway also means that day will not be recorded. Later runs are practice.
What is the Master Labyrinth?
An advanced mode with less HP and fewer fate stones, where every room is one level harder (in-app purchase). Scores are worth 1.5 times as much, and it has its own ranking.
The ranking says it is unavailable
The ranking needs an internet connection. Check your connection and tap "Retry". Your runs are still saved on the device, and scores that could not be sent are sent again later.
