FAQ
Can I play against other players?
Your opponents are ten AI masters. Matches against other players are not supported.
Can I play offline?
An internet connection is required to start matches and save match records and titles when signed in. Not all features are available offline.
Is it free to play?
The core game is free to play. Regular matches use match tickets, except matches against Hakuro, trial matches and other exempt modes. Tickets recover over time; when below the limit, they can also be recovered by watching a video ad. The Android version includes ads and optional in-app purchases.
What in-app purchases are available?
On Android, optional purchases include the All Gates Pass (access to all ten masters regardless of progress, plus board and profile cosmetics), character packs with extra artwork and stories, and Premium, which removes ads and ticket consumption for regular matches. Even with the pass, clears, titles and first-victory stories are earned through play. Premium does not include the other products. Check the in-app purchase screen on your device for available products, contents and prices.
Can I play without an account?
As a guest, you can try matches against the introductory master. Signing in with Google or Apple is required to challenge the other masters or transfer your progress to a new device.
