FAQ

How do I play?

An expression appears on the top half of the screen and a plain number on the bottom half. Tap the half you think is bigger. A round lasts sixty seconds.

What do the five levels mean?

Tap the level button on the home screen to read what a level contains and see five real examples before you commit to it.

How is Duel different from playing twice?

Both players get exactly the same problems in exactly the same order, so the two runs are comparable. You play a minute, hand the phone over, and the second player starts from a stop screen rather than a running clock. The result shows both runs problem by problem and names the ones where one of you was right and the other was not.

Why does a mistake cost a point in Duel but not in Classic?

Classic ends the round after three mistakes, which is what stops people from tapping at random. Duel has no lives, because a turn that ends eight seconds after the phone changed hands is a bad turn. Losing a point does the same job: guessing is worth nothing on average, while knowing is worth a point.

Can I reset my records?

Yes. Open the trophy screen and tap Clear. It erases every stored result and cannot be undone.

Are my records synced between devices?

No. Everything stays on the device that earned it. There is no account and no server.

Does the app work offline?

Always. It has no networking code at all.

How do I change the language?

Settings → Language. Sixteen languages, and the whole interface changes immediately without restarting.

Is it free?

Yes — no purchases, no subscriptions, no ads.
