As much as I love Cross Sums I'm no expert so other solvers may have a different opinion from mine. When I hit a tough area of a puzzle I'll mentally fill in a number and see if it will work. I wouldn't call it trial and error though because I'm not physically filling in the number and following through several steps to see if it will work. Usually with this scenario of mentally plugging in a number I'm able to rule out either a large or small digit which helps me find the right one from remaining possibilities.

I think I would have a much easier time solving Cross Sums if I penciled in the possibilities for each square when I reach a tough spot, much like in Sudoku, but I like using my Frixion pens too much when doing these puzzles! smile

So I would say logic is involved instead of trial and error, though the logic may always not be so easy to see.
