V nice 5 min solve if you understand the consequence of the ruleset. Surprised how well it works out! Well constructed

Demanding and very rewarding at the same time!

Absolutely underrated puzzle. Sad that most will miss it because the rating has dropped below 90%. It is really awesome.

As dzamie wrote, the rules do not state that all cells with r+c prime are friendly. So there can be less than 4 friendly cells in box 1.

I'm really impressed this works out to a unique solution! Also had to keep reminding myself that friendly number means prime box, but prime box does not mean friendly number.

I have a problem in bix 1 I find 4 friendly cells, r1c1=2 r1c2=3 r2c1=3 r3c2=5, has there are 4 friendly celks buecause the sum of r+c is a prime number, i only can write the numbers 1, 2 and 3, so i don t find the 4th number that can be a friendly cell. I hope i explained it well :-)

That was fun! I had to be careful after some coloring and spacing possible digits to not "identify pairs and triples" - hold back the instincts and really think about the rule set.

Took a sec to wrap my head around the rule set implications, but then flowed nicely. Fun puzzle. Thanks
