** TODAY'S PUZZLE **
A lot of people are aware that the minimum number of given digits necessary to create a classic sudoku with a unique sudoku is 17. The constructor Lepton has discovered that, in a 10x10 grid, WHERE THE SOLVER MUST FIND THE LOCATIONS OF THE NINE 3x3 BOXES, it is possible to REDUCE the number of given digits to just 14. This seems so counterintuitive and yet it is true!!!

Have a go at the puzzle here:

Rules:
Draw nine non-overlapping 3x3 boxes, and place the digits 1-9 once each in every box. Digits cannot repeat in any row or column. Cells outside boxes do not contain digits.
