Plato's Primes
(Published on 31. October 2020, 19:44 by steelwool)
Plato has just finished setting his new killer sudoku.
Normal killer rules apply, cages sum to the number indicated and digits are not repeated in a cage.
He also included some little killer diagonals, which sum to the number given and digits might repeat.
BUT, there is a problem!
Plato forgot to add any of the digits.
Fortunately, we were told all the numbers are prime.
Plato also said all the cages with prime sums that can be drawn are present.
The puzzle can be solved online using this link:

Solution code: Enter the digits from row 8 followed by column 4, with no spaces

@RockyRoer: [SPOILER] I used all manner of tricks to complete this - took me close to 2 hours. For instance 1468 cannot occupy any orthogonally connected area of 4 squares (not in a cage), since you can make 19 with all. Thus an area as described must hold a 9. I will not say anymore here, but suffice to say - you will need patience for this puzzle :)
Shhh [sploiler] The puzzle is as much about the not-primes!

Very nice puzzle, but harder than 2 stars in my opinion. I rated it hard. Brilliantly built dude (or dudette)!
Thanks @Tom1i. Steelwool is the man!
