Battleship Solitaire
Place the fleet using the row/column counts — ships never touch. One unique solution; answer shows in the app.
Example
🔒 The answer is never printed — it shows in the app (and via the page's QR code).
How to play
- A hidden fleet is on the grid. The numbers beside each row and column say how many squares in that line hold a ship piece.
- Ships are straight and never touch each other, not even at the corners.
- Use the counts and any starting hints to figure out where every ship goes. There is exactly one solution.
How it works
Generated fleet placement with the no-touch rule, and a solver that guarantees exactly one solution before it ever prints.
What you can set
- Appropriateness dial (kindergarten → adult) — tune it per card. Scales the grid 6×6 → 9×9 and the fleet size.
Age dial (1–20): 1–5: 6×6 board · 6–10: 7×7 · 11–14: 8×8 · 15+: 9×9 with a bigger fleet.
