Futoshiki Logic Puzzle – Sudoku Inspired Number Game

Train your brain with Futoshiki, a Sudoku-inspired logic number puzzle that adds a fresh twist: inequality signs between cells. Fill the grid so that numbers never repeat in any row or column—then use < and > clues to determine which numbers must be bigger or smaller. Simple rules, deep logic, and satisfying “aha!” moments.

If you enjoy Sudoku, Kakuro, Nonograms, or other classic brain games, Futoshiki will feel familiar—yet uniquely challenging.
