👑 Crown Grid
🎯Goal: Place exactly one crown in every row, every column and
every coloured region.
👆How to play: Tap a square to cycle it: empty → ✗ (a "not
here" mark) → 👑 crown → empty. Long-press to clear it at
once.
🚫No touching: Two crowns may never sit next to each other —
not side by side, and not even corner to corner.
🏆Win: Every row, column and colour has its one crown, and no two
crowns touch. Every board has exactly one answer — you
never have to guess.
