HASHI
What is Hashi?
Hashi's full name is Hashiwokakero. It means "Let's build bridges!" and that's exactly what you have to do. It's a wonderfully engrossing game; you can scribble over an easy one in a couple of minutes, or lose an hour staring at a harder challenge until your eyes water. It's a great mix of logic, spatial awareness and even instinct - so long as you never entirely trust that gut feeling!
In Hashi, the world is made up of a number of 'islands', and your job is to link them together. Here's an example puzzle:

An easy Hashi puzzle
Each island has a number, and that's how many bridges it needs. Easy enough, except the bridges have to follow these three rules:
- They must be vertical or horizontal (no diagonals or wiggly lines)
- They can't cross other bridges
- You can't have more than two bridges along any one route
And in the end, every island must be connected to every other one.
Of course there's only one solution! And of course, no matter how tempting, you never have to guess. (By the way, here's what the board looks like when it's solved):
