In this spot-the-difference game, the objective is to find all the differences between two pictures within a given time limit. Players must click on the differences to mark them and progress to the next level. Each level has multiple differences to find, and the game offers different difficulty levels from novice to expert, each with varying time limits and energy points. Players' energy points gradually recover over time but are depleted when they fail or run out of time. Successfully completing a level allows players to advance to more challenging levels.
