It’s the new Slitherlink! (This is number eleven in a series of DS puzzle games from Hudson, Slitherlink was number five. It’s all in Japanese, but it takes all of about ten seconds to figure out the menus.)

Starts off with the 6×6 puzzles, which take about thirty seconds, but soon grows. I’m on the 10×10 puzzles now and most of them are taking me about two and a half minutes to do, so it’s perfect little bite-sized gaming.

I could describe the rules, but that would be tedious and confusing. It’s probably best if you just click this link and try it for yourself.

Beware, though – it’s horribly addictive.
