1 problem with picross - sometimes the board leaves you with no other option than to guess. that's not very puzzley is it?
or am i missing something?
I gone through all the Easy and almost half the Normal mode puzzles, and all of them were done logically without guessing.
If you get stuck, you should concentrate on any large numbers and determine the possible places they can go. For example, on a 10x10 grid, the sequence 2 4 doesn't looking very promising, but it's enough to tell you that the 7th column will be filled because the 4 will always overlap that spot.
