I'm fairly certain, but feel free to send me your progress and I can compare it with my copy.

I've managed to fill this one though I know I made a mistake in my reasoning for 16 (I've ended up with something consistent in that block, but only probably unique) - I've only done the difference blocks and the multiplication blocks (to the level of identifying which pair of numbers produces each product) and odd numbers elsewhere (things like 25s where there are only a few possibilities based on other days, and the clues limit it further)

Are you sure this clue is correct? Because I can't put any number in left column, 3rd and 4th square :/
