Futoshiki (meaning 'unequal' in Japanese) is a popular numerical logic puzzle. Players fill an N×N grid so that each row and column contains digits 1 to N without duplicates, while respecting all inequality signs between adjacent squares.

How do inequality signs work in Futoshiki?

A greater-than sign (>) or downward pointing chevron (∨) means the first cell must be strictly larger than the adjacent cell. A less-than sign (<) or upward chevron (∧) means the first cell must be strictly smaller.

What is the best Futoshiki strategy?

Start by identifying the largest number (N) and smallest number (1). The largest number cannot be on the smaller side of an inequality, and 1 cannot be on the larger side of an inequality.

How to Play Futoshiki

Futoshiki combines the Latin-square satisfaction of Sudoku with inequality mathematical logic. Your objective is to place digits 1 through N so that each digit appears once per row and column, and all inequality constraints are satisfied.

🔢 Latin Square

Every number from 1 to N appears exactly once in each row and column.

⚖️ Inequality Clues

Greater-than (>, ∨) and less-than (<, ∧) symbols govern relationships between adjacent tiles.

✏️ Pencil Marks

Jot candidate numbers down in empty cells to test logical eliminations safely.

Futoshiki Solving Techniques

Inequality Chains: If you see a chain like A < B < C in a 5×5 grid, A can only be 1 or 2, and C must be at least 3, 4, or 5.
Eliminating Extremes: The number 5 can never be on the smaller side of an inequality, and the number 1 can never be on the greater side.
Cross-Referencing Rows and Columns: When a number is locked into a column, use it to eliminate candidate pencil marks in intersecting rows.
