What If A Sudoku Contained Zeroes? Lots Of Zeroes??!

** TODAY'S PUZZLE ** A very very clever debut puzzle on the channel tonight from Invi and his sudoku Zero Sum. The twist on normal sudoku rules is simple but deadly and leads to some original and fascinating logic. Not at all easy but extremely rewarding! Play the puzzle at the links below: https://sudokupad.app/9iskh68h4z Rules Fill the grid with the digits 0-9 such that each of the digits 1-9 appear at most once in any row, column or box. The digit 0 may appear any number of times in the grid. For every row, column, and box, its digits must sum to the total number of zeroes in the puzzle. The 3x3 region borders divide the blue line into segments with each segment having the same sum . Cells separated by an X sum to ten. Arrows between cells point to the smaller digit. ** BRAND NEW COMPETITION ON PATREON ** On 1 September we released a new Sudoku Hunt competition on Patreon. There's 8 puzzles to solve by 20 September to win the chance to come onto the channel and solve a puzzle with us! Simon has also completed a series of videos (7 hours!) attempting a very difficult cryptic crossword called Periodic Location by Nebuchadnezzar.   / crackingthecryptic   ▶ LAST NIGHT'S STREAM: LORELEI AND THE LASER EYES ◀ You can (re)watch tonight's stream of Lorelei and the Laser Eyes here: https://youtube.com/live/hj-J9oRDHOU ▶ ZETAMATH'S WORM: OUR BRAND NEW APP ◀ We've released a brand new collection of sudoku puzzles by Blobz.
