Difficulty levels refer to the varying degrees of challenge presented in tasks, games, or activities. They help users gauge how hard a particular task might be, allowing them to choose an appropriate level based on their skills and experience. Commonly, difficulty levels are categorized as easy, medium, and hard, with each level offering a different experience. In video games, for example, difficulty levels can affect gameplay mechanics, enemy strength, and available resources. Players may select a lower difficulty level to enjoy a more relaxed experience or opt for a higher level to test their abilities and achieve a greater sense of accomplishment.
