This is a Tapa puzzle, with a twist. The borders between some cells may be either thick or nonexistent. A thick border separating two cells means one is shaded and the other is not. A lack of a border means the two cells are both shaded or both unshaded.

Beautiful variation!

Fun, thanks! This variation seems to have a lot of potential.
There’s something wrong with the image compared to your other PNGs: The white background is not all of the same color, so solving using a stupid image editor isn’t as nice as usual.

It’s a thumbnail. Click on it. Kinda like my blog, except for some reason even more people miss it there than here. 😛
Many of Palmer’s recent-ish puzzles have been thumbnails, because I guess he stopped rendering them in two different sizes.

In the past couple of months there have been a lot of changes and tweaks to the drawing code, and the smaller drawing sizes now have various issues like some things drawn off-center or text with too much or too little anti-aliasing. Rather than spend the time fixing those, I decided to just stop supporting small sizes, which is going to save me a lot of time since they have always been really hard to get right.

I like this variation a lot. Wonderful idea.

What difficulty is this?
January 5, 2012 at 2:03 am |
The difficulty of these weekly puzzles in general will be pretty random; this particular one is medium leaning towards easy.

This is the coolest Tapa I’ve ever seen, even if it wasn’t super-tough. Nicely done 😀

bsmith at PuzzlePicnic just posted a puzzle that follows one of these new rules, but in a confusing way: http://www.puzzlepicnic.com/puzzle?3207
Over there, it shouldn’t be “no 2×2 squares,” but rather “no surrounding a vertex,” which extends to other non-square grids. But then if two cells share a side of 2 or more, that would require adjustment or clarification.
