Two players are playing a coin tossing game. Player A wins $1 when the coin comes up heads and loses $1 when it comes up tails. Player B is unaware that the coin is weighted so that p(heads)=.52. They start with $4 divided in one dollar units between them. They play until one player has no money (is "ruined").
