About this board
The 10 near the bottom-right is the anchor: on a board five cells wide it can only be the bottom two rows. Above it, the wide 3 and the 6 on the right edge close in, leaving three narrow columns at the top. This is the first board with clues that show a shape but no number, so the tall icons decide those patches.
