900 color squares too

It is a definite challenger!! This and its "twin" (same puzzle, different colors) have the longest solve times I think I have ever seen in the top ten. I didn't mean for it to be so hard when I made it, but I'm happy to see so many take it on!! Thanks to all of you brave solvers!!

I have solve over 2500 puzzles on Jigidi and I must say I almost gave up twice. The hardest to solve so far, thanks irjeni
