Very....very challenging....but also very logical all the way....would be a perfect puzzle...if not for the fact that its obviously just random dots placed around with no real design, its strickly made to be a dot finder and thats it....
OK. It's logical. But I prefer to have a good image, if I have to work that hard for it. I wouldn't really call it a challenge, because it wasn't really difficult, just fiddly. Still, thanks.
