Every day there's something new in Schrö's box. Ask ChatGPT 20 yes-or-no questions, in any language, and figure out what it is before everyone else does.
Same mystery for everyone on Earth. One try a day. No account, no app to install.
Up to 20 yes/no questions. The cat answers yes, no or purrhaps (when it truly depends).
Name it when you think you know. Stuck? A hint costs 2 questions. A wrong guess costs 1.
Brag with a row of dots that gives nothing away, and keep your streak alive tomorrow.
Today's answer stays in the box for
about 16 more hours
Then the whole world finds out together. Live stats for #1 →
Green for yes, red for no, yellow for purrhaps. Your friends see how you did, not what it was.
Schrödinger's famous cat is both alive and dead until someone opens the box. Schrö is our version: whatever's in today's box is everything at once, until you ask the right questions.
It's the honest answer when something genuinely depends ("Is it green?" for an apple). It still costs a question, so ask sharper ones.

At midnight where you are. The answer is revealed for everyone at 12:00 UTC the next day, once every time zone has had its turn.
