I'm rather good at the game that ofter appears at school fetes,
where you push a 2p down a ramp and land it on a chequered board. Of course, all you win is more 2ps, but it kept me entertained at many a school fete when I was a boy.

Similarly, those machines in arcades, where you put 2p in the slot in the hope of pushing of more 2ps from the moving platform. You won't make any real money, but you can usually find a neglected 2p that someone has left behind in the prize bucket, and thus have a free afternoon's entertainment*. The 10p ones are evil, though, particularly if they have prizes sitting on top of the money, as this just serves to hold it all in place.

*Disclaimer: you may not find this game to be entertaining.

I bloody loved those 1P and 2P machines as a kid.
I think the 10P ones were rigged, and perhaps the 1 and 2P ones were a type of loss-leader?
I want a go on a 2P machine now!
