I couldn't sleep so I decided to make a little snack puzzle inspired by Shintaro Fushida-Hardy's 5x5 and Qodec's 6x6 of the same ruleset. You can play it here on SudokuPad.
Rules:
Each row and column contains the digits 1-4 once each. Digits in a cage sum to a prime number but no two cages sum to the same prime. Digits in a cage MAY repeat.
This should be about a half star difficulty.
Solution code: Row 1 followed by row 4

I really hope you'll be able to sleep next time, but this is very much the next best thing. Thanks!

Very easy snack. Who will be the first to do a 9x9? Thank you.

You're welcome, I both look forward to and dread the 9x9

The check says my solution is right, but the code is not accepted.

May have been an error or I just overcomplicated it, updated for you.
