Prime Arrows

(Published on 11. February 2026, 00:21 by Will Power)

Normal Sudoku rules apply. ARROWS(+)- Numbers on arrows sum to the number in the arrow's circle or pill. Pills are read from left to right or top to bottom. ALSO, all circles and pills are DIFFERENT prime numbers. KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are shown.

Oh, very fun. This is probably on the higher end of 2*, might be 3* for someone who isn't used to pill arrows (or is unfamiliar with prime numbers).
The restriction of *only* prime numbers sharply reduced the number of possibilities, which was very helpful, and there are several instances of a couple of arrows working out to nicely fill one or two boxes entirely.

Hello, all. I don't have anyone that reviews my puzzles before I release them on LMD. I have one that I want to try something different. I will give you the links here, and once you solve it, tell me whether it is worth releasing. You tell me if the bifurcation is unacceptable. I don't want to release it and get a lot of negative comments, so I'd rather wait until some of you solve it and give me a green light.
