Curiobox is a word game in which you solve crossword puzzles by forming words from a letter circle. You unlock the stages in order, receive a score based on your time and hint usage, and try to beat your own record.
The application is currently in an early version; your questions and bug reports go directly into development.
Report a problem, ask a question
If you have found a bug, if something seemed unclear, or if you have a suggestion, write to us:
For your report to be concluded quickly, it is enough that you include the following:
- Your username shown in the application (it is written on the Profile screen)
- Your device model and operating system version
- What you did and what you expected — if possible a screenshot
E-mails are usually replied to within a few business days.
If you are a TestFlight beta tester
If you are using the application through TestFlight, the most practical way to give feedback is TestFlight's own feedback feature: take a screenshot while in the application and use the "Send Feedback" button on the screen that appears. A screenshot and device information are automatically attached to a report sent this way.
Of course, e-mail is always open as well.
Frequently asked questions
How do I protect my progress?
Do not delete the application from your device. Because Curiobox does not create an account, your identity lives on your device. If you delete the application, your session information is deleted as well and when you reinstall it you start as a new player — your old scores, records and the stages you unlocked cannot be brought back.
For the same reason, in this version progress cannot be moved to another device. Progress transfer on device change is a feature planned to be added in the future; today it does not exist.
Why do you not ask for an e-mail address or a password?
Because you do not need an account to enter the game. The first time you open the application, an anonymous player record is created for you on the server; this record consists of nothing but a random identifier and does not identify you in real life. No e-mail address, phone number, full name or password is requested.
The price of this is the situation in the question above: because there is no account, there is no account recovery either. This is a deliberate choice — the details are on the Privacy Policy page.
Why can I not change my username again right away?
You can change your username from the Profile screen, but 7 days must be waited between two changes. A change made before this period elapses is rejected by the server and a warning is shown to you.
In addition, the username must be 3–20 characters, must contain only letters, digits and underscore, and must not have been taken by another player.
