Salmon Survival Game

Rob Donkin, one of my sons, is enjoying his break from university but I have not been able to get him out fishing. Instead he is building computer games. So I was chatting to him about salmon migrations and how tough it was for the fish to get back up the river. How do they avoid all those anglers?

Inspired, he came up with this Salmon Survival game. Why not try it? It's easy to learn but not so easy to avoid those anglers and their fishing flies. My fish keep getting caught on the lower beats. The river narrows the further you get. I also notice that the most successful anglers are the ones that keep their flies moving in the water. Just like real life then.
