About the Monday, 16 February 2026 puzzle
This is the hard 6×6 Quilt board published on Monday, 16 February 2026: a 6×6 grid divided into 15 cages, 3 of which are single cells that hand you their values outright. Fill every row and column with the numbers 1 to 6 without repeating one, so that each cage reaches its target. It is a KenKen-style math and logic puzzle — the genre also known as calcudoku or mathdoku — and like every Quilt board it is solvable by deduction alone, with no guessing required.
