Intrigued by Eurogamer’s 10/10 review for Slitherlink on the Nintendo DS, I did some digging and discovered PocketLoop, which is a freeware clone for Windows Mobile.
I’m not sure the game justifies 10/10, but it’s good fun, and is worth downloading if you enjoy puzzle games.
One issue to be aware of is that the game need Microsoft’s .NET Compact Framework installed on your device. There are several different versions available, but 2.0.2, which seems to be the most recent, worked fine for me. Unfortunately the framework takes quite a lot of memory, so it’s probably not appropriate if space is tight.
