About this board
Twenty clues make this the busiest board in the set, but eight of them are fixed from the start, including a 3x3 nine near the top and a 3x3 square nine on the right edge. The bottom row is a neat run of three 2x2 squares and two 3s. The middle is where the work is, with a wide 6 and a wide 10 that each have several ways to sit until their neighbours close in.
