Find what fits.

One daily game. Three secret rules.

1. Follow the clues

   Every stage starts with examples that fit a hidden rule and examples that don't.

2. Test your idea

   Try another example. Does the result support your theory? Tests are unlimited, and hints are there if you need a nudge.

3. Sort three new examples

   Choose Fits or Doesn't fit for each one, then check your answers. Get all three right to solve the stage.

Three stages, one result

Finish each stage to unlock the next. Each submitted check is a try. A wrong check adds one strike; revealing a rule also adds one strike. Tests and hints don't add strikes.

There is no strike limit. After all three stages, share your complete daily result with your tries, strikes, tests and hints. The rules stay secret.
