Before you play

Is BrainiLab free to play?

Yes. You can play the quizzes and Daily challenges for free. BrainiLab+ is an optional membership that supports the project; it does not give extra points or ranking advantages.

Do I need an account?

No account is needed to start. Guest results can appear in rankings under a generated alias. Sign in to keep your progress across devices.

What is the difference between Daily and Anytime?

Daily challenges give you one main game each day, with an optional extra. Anytime games let you practise whenever you want and choose a topic or game type.

Where should I start?

Start with today’s Daily, or choose a topic you enjoy: geography, general knowledge and science. Game guides explain the rules and give worked examples before you play.

How can I report an incorrect answer?

Send a correction with the game name, question and a reliable source where possible. Include an email address if you would like a reply.
