FAQ

Is Fynal a daily game?

Yes. Three new questions every day at midnight (Central European time), the same for everyone in your region.

Can I use a calculator?

Yes, a calculator and notes are built into the game. The only thing not allowed is looking up the answer online.

Can I play older days?

Yes, the archive has every past challenge. They do not count towards your streak.

Can I play against friends?

Yes. Create a room, send the link and play the same questions against each other. A nickname is enough.

What is a Fermi question?

A question you can reach with a sensible estimate even without knowing the exact answer. You break it into smaller steps you can estimate and multiply them.
