Ordo

A free daily logic puzzle in the style of futoshiki. Fill the 6×6 grid so every row and column holds 1 to 6, with never three even or three odd digits in a row, and follow the wedges between cells: each points at the smaller digit, and a green or red wedge also says whether the two share a parity.

A new puzzle every day, easier early in the week and harder at the weekend. No ads, no accounts, no cookies.
