Common questions

Do I need an account?
No: no email, no password — the game starts right away. A nickname and avatar are optional.
Is it a yes/no quiz?
Yes, in Topics: you read a statement and answer «Sure» or «Wrong». On the map the question is about a country — yes/no or one of four options.
Can I play with a friend?
Yes: a room joined by a short code, a one-on-one duel or the whole group. Two-player match results go to the shared leaderboard.
How long is a round?
As long as you like: you pick the round length and the answer timer before the start.
