If you're fed up with switching your brain off during long bus or train journies then check out Cardhue, which will help to exercise your coconut on your Pocket PC.
If you like solving mathematical riddles or matching up pairs, then you'll love Cardhue. It reminds me in many of ways of that old classic, Mastermind, where you had to try and figure out the combination of coloured pegs that your opponent had behind their screen.
In this case, it's not coloured pegs we're dealing with, but a series of symbols that are hidden in a grid. The rules of where the symbols might appear are pretty complex, so you'll have to have your wits about you at all times.
Graphically, the game isn't amazing, but then it doesn't need to be because this is one of those ones where you'll become hooked on the gameplay, spending hours trying to figure out what on Earth the correct combination of symbols is.
All in all, it's a great way of keeping your brain in gear on boring journies.
