Place the digits 1-9 once in each row, column and box.
Digits separated by a white dot are consecutive.
Digits do not repeat in cages.
Each cage contains a unique set of digits.
When the sum of a cage is a prime, the cage contains no primes.
When the sum of a cage is not a prime, the cage contains only primes.

Very few people played the first version, but the few who did seemed to enjoy it quite a lot. I also still believe it's a fun concept with interesting connections and I want more people to enjoy it.
So I've tried to improve on the original idea, make the connections between the cages feel more subtle and interesting and also bring the different parts of the solving path together.
I hope I succeeded and this will be a more interesting and joyful solve. Have fun.
