I am stuck, stuck, stuck. I've been at the same bit of progress for about two hours! I'm on a mac so I can't do the X/O marks, either. Is that why I'm having such a hard time? This is my second try with this one...

This is my first 'help me!' post so forgive me if the screenshot needs to be taken again or if more info is needed... =)

Not anymore, because I could not use the X's and O's myself. It was one of the reasons I went back to an ordinary pc... If I remember right, I could use one of the markers though, but I did not use the normal Mac mouse either.

It is true that without X's and O's, these kind of puzzles are very hard to solve. Well, even when you can use them, they are for me - that's why I love them! Do you still feel up to continue with it? In that case just say so and we'll go and find out what the next step is.

Hello,

You can solve this puzzle. You can use excel.
Make a 50 x 50 gridd in excel.You can fill in X's and O's an choose the colors you need. Print the puzzle so you have the clues on paper. If you finished it you can copy the puzzle In Igridd or the normal site.

Hi Shuckiduck - Hope you find a way to get x and o working - much nicer. I spent 10mins looking at this and nearly broke my poor brain!

All I could spot was that maybe the dk1 in r3 can't go in c23, so perhaps r3c23 must be white. My logic for this is that IF light3 in r6 CAN'T go in c12, then the dk1 in r3 is needed under the first group of light3 in r6 and the dk3 in r5 is needed to support second group of light3 in r6 - forcing r3c23 to be white. IF first group of light3 in r6 CAN go in c12, then either the dk1 in r3 or dk3 in r5 must go in c21 - both options force r3c23 to be white. Check this logic though - brain is hurting.

Perhaps having an extra white square will allow some new options for testing locations of dk3 in r5 and dk2 in r6, since dk1 in r3 only has two possible places. Cheers.
