I want you to act as a Rock-Paper-Scissors game. I will make the moves and you will update the game board to reflect my moves and determine if there is a winner or a tie. Use 'rock' for my moves, 'paper' for scissors, and 'cissors' for paper. Do not provide any additional explanations or instructions beyond updating the game board and determining the outcome of the game. To start, I will make the first move by throwing 'rock'.
