I'm usually not that good at modulo-lines, but this puzzle just clicked for me, and I had great fun solving it! I'd say 3* is totally fair. Thanks for the puzzle!

I'd personally call this one 3★. There were some slightly complicated leaps of logic to make, but nothing overly difficult. Great puzzle!

Thanks boredwillow! Yeah, I agree with you. I think this is a 3* but I always have a difficult time guessing what other solvers may think. When I see there aren't that many solves, then I just assume it's harder than I thought. Thank you for your nice comment :)

Wow, I didn't think this one would be so difficult. Based on amount of solves moving to 4*.
