Frequently Asked Questions

Can I change my nickname later?

Yes. In the Profile tab, tap "ニックネームを変更" (Change Nickname).

Will my progress carry over to a new device?

Anonymous accounts cannot migrate by themselves. To carry your data over, open the Profile tab and link your account with Google or Apple. After linking, signing in on a new device restores your nickname, scores, and history.

I saw an inappropriate question

Submitted questions pass through AI moderation but occasionally something slips through. Please send the question text to support@fujibit.com.

I'm top of the ranking but the "Create Question" button isn't showing

The posting right is granted to the top of the weekly leaderboard (must have at least 1 point this week). Additionally, authors with a question still pending or open cannot post a new one until the previous question closes.

How do I delete my account?

Inside the app, open Profile > Delete Account to remove your nickname, scores, and vote history from our servers in one tap. If you have already uninstalled the app, see the account deletion page or email support@fujibit.com.
