Standard Sudoku rules apply.
Cells containing numbers exactly one greater than an immediate neighbour (diagonal or orthogonal) within their box are shaded (and otherwise unshaded).
Cells with lozenges contain prime numbers.
Solution code: Row 1

I learned nothing from your first prime puzzle /facepalm
Very nice and smooth and very cool interactions in one particular place (I hope you know where I mean)!

Thanks ATK - a nice little palate cleanser after last week! Nice clear solve path and fun to solve.
---After my last couple of (unintentionally) difficult puzzles, I thought it would be nice to serve up something less chewy.
Thanks for the comment and the solve. ---ATK
