Labyrinth...

My favourite puzzles seem to vary from month to month! At one time I used only to do sudoku but I seem to be getting more adventurous in my old age (Well, middle age!) and am trying out all sorts of new varieties I wouldn't have tried before. I've recently come across labyrinth puzzles and love them. They say they use the same techniques as hanjie (I've only every done really simple ones of those) but I think they are a little easier. They are not particularly easy to come by though, so if anyone knows of a source please let me know!
