I find myself needing help with some of the Disconnect Four puzzles. I go through the puzzle carefully, making sure to avoid 4 +'s or 4 O's in a row. At some points where it's uncertain which symbol should be used I'm usually able to test each possibility. For example, if an O is placed an "uncertain" square and that winds up leading to an illegal 4-in-a-row then the square in question must contain a +. When I check the answer I'm still getting "solution is in correct" message. If someone could point out what's going on here that would help. Thanks!

I would surely like to help you. Could you give me a printscreen or another way to explain the precise place where you are stuck I could examine more in detail

I solved this puzzle again. As far as I can see, it is straight forward. No assumptions are to be made. The tricky thing might be the diagonal 4's, especially at the inner corners of the diagram.
I hope this will help

Also, the site doesn't distinguish between "solution is incorrect" and "solution is incomplete". A number of times I've pressed 'check' and got the error and found that I'd missed a square. Sometimes - on these irregularly shaped grids - it's hard to spot what you've missed.

Thanks wernie_de. I'll accept your offer. Usually I can get these, sometimes I have to resort to trial-and-error, but other times I can a test a possibility of A or B, and if A leads to a contradiction then B is the correct choice. I've used this method when solving Hamilton Mazes. I've noticed Disconnect Four puzzles are different from Tic-Tac logic. Those puzzles require a certain number of X's and O's in each line. Someday someone should publish a puzzle book with a wide variety of puzzles similar to Johan's fine Hamilton Mazes book. My neighbor Michelle (a real sweet lady) loves solving Hamilton mazes!
