I really should pay more attention to the puzzle instructions. :(<br><br>I did try to do it at lunchtime, but as I’m not quite up to the standard of some of the Nikoli regulars I didn’t have the time to finish it off. (I generally aim for anywhere from the medium time to halfway between medium and fast, depending on how much I’m paying attention!)<br><br>Anonymoushttp://blogs.warwick.ac.uk/lblackwell/noreply@blogger.comtag:blogger.com,1999:blog-2031071943178978556.post-37003080469489067562009-08-07T01:15:31.000+01:002009-08-07T01:15:31.000+01:00I’ve updated the appearance of the puzzle slightly...I’ve updated the appearance of the puzzle slightly – I’ve removed the border to try and avoid any possible suggestions that the puzzle has an “edge”.<br><br>Thomas Collyerhttp://blogs.warwick.ac.uk/tcollyer/noreply@blogger.comtag:blogger.com,1999:blog-2031071943178978556.post-32831811447802882232009-08-07T01:09:26.000+01:002009-08-07T01:09:26.000+01:00Yeah, your logic is perfect re the three adjacent ...Yeah, your logic is perfect re the three adjacent whites – what’s happening in this case is the toroidal “constraint” coming into play. There is no edge so your deduction for the black isn’t valid. That’s why I say “constraint” – what it actually is happening is a constraint is being removed.<br><br>Anyhow, the line coming out of the black has to come out through the left edge of the puzzle, and back in through the right. Actually, if you look at the black in question, it cannot go down either – as there is a another black directly below it. So it then has to go up, and hence out through the top edge and back in through the bottom.<br><br>Hope that clarifies, thanks for giving it a go :)<br><br>Thomas Collyerhttp://blogs.warwick.ac.uk/tcollyer/noreply@blogger.comtag:blogger.com,1999:blog-2031071943178978556.post-56121104555758986772009-08-06T19:25:44.000+01:002009-08-06T19:25:44.000+01:00I think I’m missing something in the puzzle.

Three whites in a row mean lines have to go through each individually and not the set, as otherwise you’d have to turn in one of the white cells to satisfy the middle of the three. However, a black on the edge means you need a line coming into the puzzle. So in the top left, I’ve end up with a T-shape in that line of four at the right side of row 2.<br><br>What am I doing wrong? :(<br><br>Anonymoushttp://blogs.warwick.ac.uk/lblackwell/noreply@blogger.com
