Can you explain the concept of doubling in bridge and how it can impact the outcome of the game?

In bridge, doubling is a strategic move where a player increases the point value of a contract. This can impact the outcome of the game by potentially increasing the rewards for fulfilling the contract or penalizing the opponents if they fail to meet it. Doubling adds a layer of risk and reward to the game, as it can lead to bigger gains or losses depending on how well players execute their strategies.
