The idea

A generator makes each case, proves that it has exactly one solution and grades how hard it is. Only then does it write the story.

  1. Cases made by code

    A generator builds each board and its clues, proves that the case has one solution and grades its difficulty. Then it writes the story in each language.

  2. The server is the referee

    The browser never gets the solution or the culprit. Each check, hint and score runs on the server, so nobody can read the answer in the code.

  3. Art and music made in code

    Code draws each sprite in one 32-color palette, and the browser composes the music live, so it is never the same twice.

  4. A reason to come back

    A new case each day for all the players, themed campaigns, streaks, stars and achievements. No sign-up and no ads.
