This simulation is based on the game described in the article by Alfino FLores [i]Who's in the Lead?[/i] in the August 2014 issue of NCTM's Mathematics Teacher.
Two people - Harry and Terry - flip a coin and record the result. If the running total of heads is greater than the running total of tails after the flip, Harry gets a point. If the running total of tails is greater than the running total of heads, Terry gets a point. If the running total of heads is equal to the running total of tails, no one gets a point.
