I realised just now that I already had a subforum that could cover it (Puzzles, Crosswords, Sudoku etc), anything specific can be added as a subforum to this forum.

Sorry :/ I didn't mean to say it was my idea. (I have to admit I've been doing some other things in the meantime so haven't been concentrating 100%)
Mr. Doodlebug was the person that suggested that we needed a puzzle section and I realised we already had a sub-forum for it. No harm meant.
Find a 10-digit number where the first digit is how many zeros in the number, the second digit is how many 1s in the number etc. until the tenth digit which is how many 9s in the number.
Here is even a harder version wit 13 digits.!!!
Find a 13-digit number where the first digit is how many zeros in the number, the second digit is how many 1s in the number etc. until the tenth digit which is how many 9s in the number.
9210000001000
The 1, 4 spaces in, is unexpected.
Here ya go.!!!
