Are there times when you have to guess?

I *loved* Gemsweeper and really appreciate you guys pointing me that direction. Gemsweeper is *total* logic, hair-pulling at times, yes. But always logic.

With WM, I'm having a hard time finding a logical answer in discovering where the tiles are. And the hints are usually worthless.

Is it possible to work every puzzle without having to guess?

TIA!

I'm wondering this too. I love this game and have already played it through twice. Most of the puzzles I can figure out on my own but a few have stumped me. Is it possible to solve all puzzles w/o relying on hints?

I don't have the patience usually to figure out how to solve the hardest puzzles without using hints. When I used to do these on paper, sometimes I would go so far as to make a copy of it and then see "well if I assume that THIS square is black, then.....". If there's a reasonably large number on an edge with only tiny numbers in the next row/col over, that often helps me figure out spots that can't hold a tile. For example, if there top row's rightmost number is a 4 and the second row has nothing but 1s in it, then I can eliminate spots starting at the right that would require adjacent tiles in the second row.
