Game levels are distinct stages or sections within a video game that players progress through. Each level typically presents unique challenges, objectives, and environments, allowing players to experience a variety of gameplay. Levels can vary in difficulty, often increasing as players advance, which helps maintain engagement and motivation. In many games, completing a level unlocks the next one, often rewarding players with points, items, or new abilities. Levels can be linear, where players follow a set path, or open-world, allowing for exploration. Popular examples of games with multiple levels include Super Mario, The Legend of Zelda, and Call of Duty.
