OUR TAKE Funny for five rules, brutal by twelve. Bookmark a chess solver.

How to play

  1. Type a password that satisfies rule 1; every new rule then appears in real time and stacks on top

  2. Later rules include digit sums, multiplying Roman numerals, moon-phase emoji and an AI-recommended chess move (rule 16)

  3. Break any earlier rule while fixing a new one and it immediately flags red and locks

Scoring tips

  1. Don't delete early characters — append to the end to satisfy each new rule

  2. For the rule 16 chess move, work out the best line on an outside board (Bxe4+ does the job)

  3. Keep Paul the caterpillar emoji fed — don't let the running digit sum starve him
