Futoshiki – a Japanese logic puzzle with a new twist.
Futoshiki is an addictive logic puzzle from Japan, similar to Sudoku but with a twist. It’s usually played on a square grid, e.g., 5 x 5 cells, where you fill in the numbers 1 to 5 so that each row and column contains each number exactly once—just like in Sudoku. But Futoshiki adds an extra challenge: inequality signs between cells indicating that one number must be greater than or less than another.
This seemingly simple twist opens up a whole new dimension of logical thinking and strategy. You can no longer just eliminate candidates based on duplicates—you also need to interpret and combine the inequalities to find the single valid solution.
A game for puzzle lovers and logic fans
Futoshiki is ideal if you love Sudoku, Kakuro, or logic puzzles in general. It doesn’t require math skills—just pure logic and deduction. The game challenges both beginners and veterans, and the difficulty is easy to adjust, from small 4×4 grids for newcomers to larger 7×7 grids for hardcore logic fans.
That makes it perfect for both kids and adults, and a great way to keep your mind sharp—for example, as a daily challenge over your morning coffee or on the train to work.

Tips and tricks for solving Futoshiki
Use elimination: If a number can’t go anywhere in a row or column except one cell, that’s where it must go.
Start with the givens: Use them as the foundation for filling rows and columns.
Leverage the inequality signs: If A > B and B is already 4, then A must be 5.
Combine rules: Consider both the classic Sudoku constraints and the inequalities at the same time.
