Logic Grid
Who has what? Use the clues to fill in the grid. Every puzzle has exactly one answer.
Example
Each kid packed one lunch. Use the clues: mark ✗ for no, ✓ for yes.
1. Neither Ava nor Kai packs the bagel.
2. Neither Ivy nor Ava packs the rice.
Answer (in the app): Ivy: bagel, Ava: salad, Kai: rice
🔒 The answer is never printed — it shows in the app (and via the page's QR code).
How to play
- Match each person to the right pet, lunch or sport using the clues.
- In the grid, put an ✗ where something can't be true and a ✓ where it must be. Each person gets exactly one of each.
- Each clue is true, and there's exactly one solution, so no guessing.
- Check your answer in the app.
How it works
Generated fresh each day: kids are matched to pets, lunches or sports. A solver checks every possible answer so the puzzle has exactly one solution, then trims the clues to the minimum. Ages 4–9: 3×3 with about 3 clues; 10–12: 4×4 with about 6. Solution shows in the app only.
What you can set
- Appropriateness dial (kindergarten → adult) — tune it per card. Picks the grid size.
Age dial (1–20): Fewer clues up to 10, an extra person to match from 11.
