Gameplay refers to the way a game is played, including its rules, mechanics and overall experience. It encompasses everything from the storyline and objectives to how the player interacts with the game world and the various challenges they face along the way. Gameplay can vary greatly depending on the type of game being played - for example, a puzzle game will have different gameplay mechanics than an action-adventure or sports game. Ultimately, gameplay is what makes playing a game fun, engaging and challenging.
