Rock-paper-scissors (RPS) is a simple, yet universally recognized game that has been around for centuries. It involves two players making simultaneous hand gestures, with the outcome determined based on a simple rule: rock beats scissors, scissors beats paper, and paper beats rock. Despite its apparent simplicity, RPS has become a popular pastime among people across all ages and backgrounds.

However, while many of us may play RPS as a casual game during our free time, there are others who take it quite seriously. These top RPS players have unlocked the secret strategies that allow them to consistently win against their opponents. In this article, we will delve into the insights gained through statistical analysis of RPS games, and explore the strategies that top players use to gain the upper hand.

Basic Strategies

The first strategy to win at RPS is to master the art of bluffing. Many top players often use the same gesture consecutively to create an illusion that they are committed to it. But at the last moment, they change their gesture, catching their opponent off-guard.

Another common strategy that is used by top RPS players is to keep track of their opponents’ patterns. By observing the opponent’s patterns, a player can anticipate which move to play next. For example, if a player notices that their opponent frequently uses paper in response to scissors, they can rely on that pattern to win the game.

Using Math to Enhance Strategies

While the basic strategies mentioned above can take a player far, the best RPS players rely on a more sophisticated approach – using mathematical models to predict the outcome of their games.

The most popular mathematical model used by top RPS players is the Markov chain, which predicts the probability of a certain outcome based on the previous steps in the sequence. In the context of RPS, using a Markov chain involves analyzing your opponent’s previous moves and estimating the likelihood of their next move based on those patterns. By doing so, a player can increase their chances of winning significantly.

Another mathematical model that is effective in RPS is game theory. Game theory involves analyzing the opponent’s psychology to predict their probable next move. For example, if the opponent is likely to play conservatively, then the player can adopt an aggressive strategy to counter it. Game theory also factors in the Nash equilibrium, which is the optimal solution in a game in which both players have a strategy to pick.


In conclusion, while RPS is a simple game, winning consistently requires skill, strategy, and a fair bit of statistical analysis. The best RPS players rely on a combination of techniques, including mastering the art of bluffing, keeping track of the opponent’s patterns, and using mathematical models such as Markov chains and game theory. By taking a methodical approach, these top players can gain the upper hand and outwit their opponents consistently. So the next time you play RPS, keep in mind that there may be more to this game than meets the eye, and by honing your skills, you too can join the ranks of the top RPS players.
