Everything you need to know about Futoshiki
Learn the rules and try a practical solving tip.
Rules
- Use every number from 1 to N exactly once in each row and column.
- A horizontal < means the left number is smaller than the right; > means it is larger.
- A vertical ∧ means the upper number is smaller than the lower; ∨ means it is larger.
- Keep the given numbers unchanged.
Tips
Tip: In a chain A < B < C, all three numbers must be different and increase from A to C. On a 4×4 board, A therefore cannot be 3 or 4.
