What Are the Strategies in Game Theory?


Martha Robinson

Game theory is an important concept in economics and other social sciences. It deals with the study of decision-making in strategic situations where one player’s decision affects the outcomes of other players. In this article, we will discuss the different strategies used in game theory.


A strategy is a set of rules or guidelines that a player follows in order to achieve their objectives. In game theory, there are different types of strategies that players can use to outperform their opponents. Here are some of the most commonly used strategies:

1. Dominant Strategy

A dominant strategy is a strategy that always yields the best outcome for a player, regardless of what their opponent does. For example, if Player A has a dominant strategy, they will always choose that strategy no matter what Player B chooses.

2. Nash Equilibrium

The Nash equilibrium is a situation where both players choose their best possible strategies, given what their opponent is doing. In other words, neither player has an incentive to switch to another strategy.

3. Tit-for-Tat

Tit-for-tat is a strategy where a player cooperates on the first move and then copies their opponent’s previous move on each subsequent move. This strategy encourages cooperation between two players and helps to create trust between them.

4. Grim Trigger

The Grim Trigger strategy is similar to Tit-for-Tat but with a more severe punishment for cheating. If one player cheats or defects from cooperation, then the other player will continue to defect for the remainder of the game.


In conclusion, game theory provides us with valuable insights into how people make decisions in strategic situations. The different strategies discussed above are just some examples of how players can outmaneuver their opponents and achieve their objectives. By understanding these strategies, players can make better decisions in various situations and improve their chances of success.
