PDN's Return / Die Rückkehr von PDN
(Published on 28. May 2026, 18:26 by PDN777)
Normal sudoku rules apply. The blue cells are box indexers. If the cell at box position A has value V then the cell in the same box at box position V has value A. For example, if R5C2 is 3, then R4C3 is 5. Also, standard arrow and little killer rules apply. (Digits along an arrow must sum to the digit in the large circle at its end. Numbers outside the grid indicate the sum of the digits on their indicated diagonal. Digits on these diagonals may repeat when otherwise allowed. I think this puzzle is 2.5 stars out of 5 for difficulty for many solvers. As always, comments welcome. Thanks!

3.5 imo, even after an easier start. Thanks for the fun to work this one out.

Corrected German translation of rules.

there's an error in the german version of the rules, where you use "Feld" to mean BOTH "cell" and "box".
level 2 in the early stages, then you hit a brick wall --> level 3
*** From PDN - thanks for the solve. Rules corrected. TY
