About the Tuesday, 18 August 2026 puzzle
This is the hard 6×6 Quilt board published on Tuesday, 18 August 2026: a 6×6 grid divided into 11 cages, none of them single-cell freebies. 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.
