Let's Get There Sloooowly

(Published on 7. August 2026, 13:46 by sujoyku)

Martha (from the Youtube channel „youcancallmemartha“) held a talk on Slow-Solving at the SudokuCon in Manchester that inspired me to set this puzzle. So grab your favourite drink, put on some music and enjoy the puzzle nice and sloooowly. :)

Rules:

- Normal sudoku rules apply, i.e. each Row, Column, and 3x3 region has to contain the digits from 1 to 9 once each.

- Regionometer: Box borders divide the blue line into segments whose sums must strictly decrease from one end to the other. If the line enters a box more than once, each segment is considered separately. (In which direction it decreases is to be determined by the solver.)

- Little killer: Digits on a marked diagonal must sum to the clue outside the grid. (If there is no conflict with other rules, digits on such a diagonal may repeat.)

Here you can solve the puzzle online:

Solve on Sudokupad

Solution code: Row 1 from left to right (9 digits in total)
