- Every digit from 1 to 8 appears once in every row, column, and region. Regions need to be determined. Every region is a set of 8 orthogonally connected cells.
- Every orthogonally adjacent cell to a circle is part of that circle's region.
- Circle digits indicate the number of neighbouring regions to that circle's region.
- Circle digits also indicate the total number of seen even digits in the indicated directions combined, including itself (when even), before an odd digit is seen. At least one even digit is seen in every indicated direction (on every arrow cell).

Nice concept and not too tricky. Careful scanning is required though, a mistake can easily be made in the counting of the even digits because circles are naughty !

Updated rules based on feedback, and added answer check to CTC!

@ScatterBrain CTC was thinking the entire grid was one region - the colors were it marking conflicts. You can turn the conflict checker off by clicking the gear icon and then clicking the "Conflict Checker" slider button.

Thanks for the puzzle! I had problems in CTC, every time I placed a digit many colours appear out of nowhere. Then if I place a hint number all the extra colours disappear again.
