More than half a year ago I invented this ruleset and presented it with this puzzle ( Primetime ).
For a long time I thought it would remain unique, but then a few weeks ago a new idea got in my way.
So I'm happy to present the sequel, one of my most difficult but hopefully also most beautiful puzzles.

Rules:

Sudoku: Fill every row, column and 3x3 box with the digits 1-9.

Primetime Killer: Digits in cages must not repeat and have to add up to a prime number.
In addition, exactly the half (rounded down) of the cells in a cage has to be filled with prime numbers (2, 3, 5, 7) (i.e. 2- and 3-cell cages: 1 prime number, 4- and 5-cell cages: 2 prime numbers, 7-cell cage: 3 prime numbers).

Have fun solving!
