1. Fill the 5x5 grid with numbers 1 through 5.
2. Each number must appear exactly once in every row and column.
3. Respect the inequality signs (< and >) between cells; the numbers you place must satisfy these math constraints.

Futoshiki is known globally as More or Less, Unequal, Hutoshiki, and Inequality.

While both are Latin Square puzzles, Sudoku uses 3×3 block constraints in a 9×9 grid, whereas Futoshiki uses inequality signs (> and <) between adjacent cells in a smaller 5×5 grid. Futoshiki requires reasoning about relative values rather than absolute placements.

The most common size is 5×5, but Futoshiki can also be played on 4×4, 6×6, 7×7, and even 9×9 grids. Larger grids provide significantly more challenge as candidate interactions increase exponentially.

No arithmetic is required. Futoshiki is a pure logic puzzle. You only need to understand “greater than” and “less than” relationships. The numbers 1–5 are simply symbols representing an ordered sequence.

Yes. Every puzzle on Daily Logic Games has a single unique solution that can be reached entirely through logical deduction. Guessing is never required.

Look for absolute extremes. For example, in a 5x5 grid, a cell with a “<” pointing away from it cannot be a 5, and a cell with a “>” pointing towards it cannot be a 1.

Yes. As puzzles get harder, you must use techniques like hidden singles, naked pairs, and chain implications where A < B < C restricts the possible values for all three cells.

A properly designed Futoshiki puzzle will always have exactly one unique solution. If you find multiple valid grid fills, the puzzle is logically flawed.
