My idea is this
Rock, Paper, Scissors
case1
if I want to beat the stone,
first as a player, choose scissors
I become scissors, and I beat paper
and transformed paper, I beat the rock
case 2
if I want to beat the scissors
first as a player choose to paper
being role earned him the rock
and since I beat rock scissors
case 3
I beat the paper
choose as the first player to the rock
I beat being rock scissors
and since I beat paper scissors
i could help with a single case please
