If you are coming to the Edinburgh Festival, I am performing ‘And the goat remained a goat‘, with musicians The Creative Martyrs at 5pm each day in the Voodoo Rooms. There will be amazing magic, creepy music, rare film footage, and several paranormal happenings (photo by Gordon Rutter).

So, to the puzzle. On Friday I set this puzzle…..

Can you create 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.

If you have not tried to solve it, have a go now. For everyone else, the answer is after the break.
