Transfer of information in Parrondo's games

We study the relation between the discrete--time version of the flashing ratchet known as Parrondo's games and a compression technique used very recently with thermal ratchets for evaluating the transfer of information -- negentropy -- between the Brownian
particle and the source of fluctuations.
We present some results concerning different versions of Parrondo's games showing, for each case, a good qualitative agreement between the gain and the variation of the entropy.
