Rock, Paper, Scissors

Rock, Paper, Scissors (RPS) is a better known game than Matching Pennies.

Rock, paper, scissors championships are regularly held among humans - and several computer tournaments have been held.

However, matching pennies seems like a simpler and more fundamental game. There are only two possible moves and no draws.

Binary is closer to the native language of computers than ternary is.

I think this means that Matching Pennies is a better game for studying sequence prediction with - and it is why it has been selected here - rather than Rock, Paper, Scissors.
