Shikaku Puzzle: Snapbox

Snapbox is a quiet number puzzle in the shikaku style. Every number on the grid is the size of the rectangle that belongs to it: a 6 needs a box of six cells. Drag the boxes out until they cover the whole grid, with exactly one number in each.

Every board has exactly one solution and a par of one box per number, so there is never anything to guess.
