If you fancy a bit bigger but not too difficult #maths #puzzle, I just published a #crossnumber on my blog! I promise it’s much easier than the #Chalkdust Magazine one.

Correction: 18D should read ”Each digit is the last digit of twice the preceding digit”. Thanks @christianp for spotting this! (And very ace to solve a puzzle with an error in it 😎)

I’ve now updated the original post with a solution. Hoping that we found the same one!

@petrilaarne that was really fun! But I couldn't get 18D to work. I got 98262248, but the second-last digit needs to be 6 for the rest of the clues to work.
