I was playing the puzzle game Sand Slides on iPad where coloured sands fall from the sand chutes. I wondered how to simulate the movement of sands in such games. Does the program need to simulate each and every particle of sand? If that's the case, that sounds like a lot of computation for iPad CPU. Or is there other strategy to simulate this?

If each 'sand corn' needs to act differently to the world, then each 'sand corn' must be an object for itself, which means have it's own physics computation. I would love to hear if there's some other logic too it though.
Since such physics seem to be very small and many, something like a GPU would most likely run it better than a CPU, I have no idea how the iPhone works though. What I mean is a GPU usually has many cores while a CPU has less, but bigger ones.
