Rules
- Normal Sudoku rules apply.
- Anti-39: Apart from the given 39 in Box 5, there must be no other instances of 39 that could be read orthogonally (from left to right or top to bottom) in the grid. 93s are allowed.
- Prime Sequence: Starting from the bulb at R1C1, work your way down the rainbow zeta to R9C4 by following a string of unique prime numbers from 5 to 39. The prime numbers may be in any order, but must be read from bulb to tip. (i.e. If the last number in the sequence was 37, there would be a 3 at R9C5 and a 7 at R9C4) The digit at R2C4 is repeated for the line.
- German Whispers: Adjacent digits along a German Whispers line must have a difference of 5 or more.
- Arrow: Digits along an arrow must sum to the number given in the circle. (Or 39 for the large arrow)

Finding the primes was fun! Then, in the endgame i struggled for a while and saw the rules again, and realised that i had forgotten the anti-39 :). Thanks for the fun puzzle, @ MicroStudy :)
