How to play Futoshiki
Futoshiki means "inequality" in Japanese. Fill the grid so each row and column has every number once, while obeying the signs.
The rules
- In a grid of size n, each row and column contains 1 to n once.
- A sign between two cells shows which one is bigger: the open side faces the bigger number.
- Some numbers are given to start you off.

A cell that is smaller than its neighbor can’t be n; a bigger cell can’t be 1.
Follow chains of signs: a < b < c means a is at most n−2.
Use Notes to track candidates.
Tips
- Long chains of signs are the best starting points.
- Combine signs with the row and column rule.
