Sequence Counters
(Published on 12. February 2026, 10:00 by FIT7Y)
Rules:
Place the digits 1-9 once each into every row, column, and box.
Digits in a big circle indicate the length of the longest strictly ascending sequence(s) of consecutive digits that can be made from the (up to 9) digits in the 3x3 of cells centered on that big circle.
If a big circle has no consecutive digits in the surrounding cells, that is treated as a sequence of length 1.
Small circles separate consecutive digits.
Have fun solving!
