These little navigation challenges were highlighted in TheOMM news email, I'd not seen them before, they are really good fun and a nice refresher:

Maybe they have been posted before, but i couldn't find them

Anyone know of any other similar challenges/training? Would be great if there was something like this that was a bit more interactive, not needed, but I kinda wanted to be able to commit my answer before the reveal.

If it was gamified somehow, leaderboards on how quickly the problem was solved perhaps? and there were hundreds of these it would make for a great learning experience.
