Dynamic Difficulty Adjustment (DDA) is a game design technique that automatically alters the difficulty level of a game based on the player's performance. If a player is struggling, the game may become easier, providing more opportunities for success. Conversely, if a player is excelling, the game can increase in difficulty to maintain a challenging experience. This approach aims to enhance player engagement and satisfaction by ensuring that the game remains enjoyable for a wide range of skill levels. DDA is commonly used in various genres, including action, role-playing, and puzzle games, to create a more personalized gaming experience.
