Cycles
(Published on 16. September 2026, 08:00 by Kaktuslav)
Rules: Normal 6×6 sudoku rules apply.
Cycles: In each row, a digit N points to the cell in column N of that row. Following these pointers divides the row into cycles. Every cycle of length at least 2 contains exactly one circle, whose digit is equal to the length of the cycle. No other cells are circled.
Solution code: Column 1 (from top to bottom)

Wonderful puzzle! There were a lot of really neat interactions and some really fun deductions along the way
I've made a bunch of cycle constraint puzzles if you like this sort of thing.

Amazing puzzle! Once I started to eliminate impossible values, the solution came together quite quickly.
