FoldingStory is a digital version of the classic classroom collaboration story game, in which participants take it in turns to add the next line to a story until the whole thing is complete. However, each player can only see the last couple of lines, and hence have no idea how the story goes before that point.

As you'd expect, this can lead to some very strange tales, as characters and plots twist and turn all over the place. Using FoldingStory is a breeze - you simply sign up, then add the next line to a story. Once the whole story is completed, you'll be send a copy in your email, and you can then 'like' any section of the story, to show your appreciation to other players.

I didn't think I was going to enjoy it at first, as you find a number of people write some serious drivel that isn't very funny or interesting and simply spoils a story. However, once you get properly into it, there's plenty of fun to be had. Plus, it's great that it's quite a passive experience - you can add a line or two, then forget about the game. Hours later, you'll receive the end result, have a good laugh, then add some more lines, and repeat.

Definitely worth checking out to see if it's your kind of thing. Go play at the FoldingStory site.
