Another one of my favourite puzzles is hashi, which I've also seen called Bridges puzzles in magazines - I assume that one of them must be some sort of Japanese name and the other an English one?
Anyhow, not knowing what the Japanese means then bridges is a good description for anyone who hasn't come across it.
Basically the way hashi works is that you have a series of numbers in circles on a rectangular grid. The numbers represent how many bridges are to be drawn between that cell and neighbouring cells, but there cannot be more than two bridges connecting different regions. Also bridges cannot cross over, must be horizontal or vertical, and once the puzzle is finished it must be possible to move from one island to any other in the puzzle by moving over the bridges: in other words none of the bridges can be isolated but must ultimately all be connected together.
Hashi is one of those puzzles I find quite hard to come by but a reasonably hard hasi where you need to think of the different pieces of logic can be really good fun... so I know there are lots of requests here, but one of mine would definitely be a hashi magazine
