Topic description:

The rock-paper-scissors game has three punch shapes: rock, scissors, and paper. Represented by letters A, B, and C respectively.

game rules:

1) The winning and losing rules between punching shapes are as follows: A>B; B>C; C>A

A letter to the left of ">" indicates the relative advantage shape. A letter on the right indicates a relatively disadvantaged shape.

2) When there is and is only one punching shape that is better than other punching shapes in this round, the player with that shape is the winner. Otherwise it is considered a draw.

  For example, 1 three players punch A, B, and C respectively. Due to a three-way advantage cycle (i.e. no one is better than the other puncher), it is judged to be a draw.

  For example, there are three players, punching A and B respectively. The one who punches A wins. 

  For example, there are three players, and all punches are A. Judged as a draw

3) When a tie occurs, there is no winner. When there are multiple winners, both are winners.
