About this board
The wide 8 takes a 4x2 slab of the lower rows, and that fixes almost everything above it: a 2x3 six in the top-left and a 2x2 four in the top-right. What's left is a tall 3 down the middle and two small 2s on the right, and the bottom-right corner can only go to the 2 just above it.
