Tenfold

(Published on 17. September 2026, 06:18 by Tessarin)

Normal Sudoku rules apply.

Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.

Digits along each straight segment of the loop, including the turning cells at both ends, sum to 10.

Digits along each arrow sum to the digit in its circle. Each circle is on the loop.



SudokuPad

Solution code: Digits on the loop in row 7 (left to right) followed by digits on the loop in column 3 (top to bottom)

I did not expect it to flow this beautifully and naturally, but it did! I agree with Snookerfan that by solve time it was 2*, but it would be un unfair rating towards newer players, so a final 3* is fair I think. Congratulations!

Very nice! Fascinating ruleset and break-in. Very smooth afterwards. By solve time 2 stars, but because of some of the break-in logic, I gave it 3. Thanks
