"""Rock-paper-scissors is a hand game that is played by two people. The players count to three in unison and
    simultaneously "throw” one of three hand signals that
    correspond to rock, paper or scissors. The winner is determined by the rules:

    Rock smashes scissors
    Scissors cuts paper
    Paper covers rock
