Pro Challenge Official Rules
Last updated: 2 November 2026
1. Sponsor
The Pro Challenge is run and sponsored by Nautiluse Limited, a company registered in England and Wales (company number 14904815), registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom, the developer of QuizUni. Apple Inc. and Google LLC are not sponsors of the Pro Challenge and are not involved in it in any way.
2. Who can take part
Any QuizUni account holder who meets the age and consent requirements of the Terms of Use can take part. Entry is free and no purchase is needed. Each account plays in its own country and can win the prize once.
3. How it works
When your Challenge starts, the app shows the number of friends you need (the goal) and the time window, both set per country and shown before you begin. Share your invite codes. A friend counts when they create a new QuizUni account with one of your codes and finish their first duel before your window ends. Each code is valid for the number of hours shown in the app and can be used by one new account. Friends who already had an account, fake accounts and additional accounts of the same person do not count.
4. Prize
If you reach the goal in time, you get QuizUni Pro for the number of days shown in the app (one year at the time of writing). It is added to your account automatically, is free, does not renew, has no cash value and cannot be transferred. It does not change your score, rank or questions. If you already pay for Pro, your paid subscription is not affected or refunded.
Friends who sign up with your code receive the energy gift shown in the app, whether or not you reach the goal.
5. Fair play
We may disqualify entries and remove prizes obtained through fake or duplicate accounts, automation or any other breach of the Terms of Use.
6. Changes
We may change the goal, window or prize for future Challenges, or stop offering the Challenge. A Challenge that has already started runs to its end under the terms shown when it started.
