Prime Miracle Killers 7x7
(Published on 26. May 2024, 21:11 by Joanie)
Each row and column must contain the digits 1-7 once each.
Prime cage rules: Each cage must sum to a distinct prime number. Digits may repeat, but only after 1-7 have been placed already in the cage. For the purposes of this puzzle, 1 may be counted as a prime.
Little killers: Digits on the marked diagonal must sum to the number above the arrow.

Some nice mental arithmetic here :) The mathematics teacher in me is going to suggest "non-composite" as an alternative to "pretend 1 is a prime", but the puzzle solves nicely either way ;)

Nice little puzzle, thank you! A bit surprised that all lowest primes skipping 2 sum up exactly to the grid sum
