How to Win at Rock-Paper-Scissors
Calculates ways to improve your chances of winning at rock-paper-scissors. (Winning 100% of the time is impossible, but statistical methods can improve the probability.)

| In the case of a tie |
According to Professor Mitsuo Yoshizawa of Obirin University, research on rock-paper-scissors revealed that “rock” was chosen with a frequency of 35.0%, “scissors” was chosen with a frequency of 31.7%, and “paper” was chosen with a frequency of 33.3%.
For the first round, you should simply throw “paper,” which beats rock.
There is also a certain pattern for ties: the probability of throwing the same move 2 times in a row was limited to 22.8%.
For example, if there is a tie with “Paper,” there is a high probability that the next move will be “Rock” or “Scissors”; therefore, the move that either beats this or does not lose to it is “Rock.”
Consequently, in the event of a tie, you should simply choose the move that loses to the move currently being played.
