At the Daily League that was started on Facebook, today we have the Classic Sudoku by Bram D L.
Each row, column and region must contain the digits from 1 to 9.
Outside each row and column the distance between two digits in that row or column is given. The order of the digits is top to bottom and left to right.
Clicking on this link will take you to Bram's blog where the image is hosted along with some other world class sudokus and puzzles.
