- No cage may include a gray cell or another cage.
- Each combination of five-cells that sum to 25 may only be used once.

Not easy, but not too hard compared to your usual. Very nice and enjoyable, especially once I started using a pen and a little piece of paper to keep track of the available sums. Thanks for this beautiful puzzle!
Note: I started by trying to use all twelve pentomino shapes as well, thinking their shape was also somehow a "5-cell combination", but I quickly had to dismiss the idea after running into a wall with this idea.

Appreciate the feedback (and of course the solve).
I was hoping to have a way to allow for the cage calculator from sudoku pad to be able to be used, but I had to make a choice on the ruleset and just couldn't make an interesting puzzle where I gave all the cages.
So either using a text editor or having a notepad handy does really help on this one, but not absolutely necessary.
I also thought about incorporating all the pentominoes as well, since it just so happens that the number of different shapes is exactly the number of combinations to 25 in 5, however while doable proved to create a frustrating puzzle so I scrapped the idea.
Anyway, glad you enjoyed the puzzle and I did put in some extra effort to make sure it wasn't too difficult..
