Begin the game by clicking on the 'Play' button. Look carefully through the festive vehicle images to locate the hidden keys. Each level asks for you to find 10 hidden keys within the image. Progress through 6 levels to complete the game. Keep in mind that the time is limited, so be swift to find all keys before time runs out. Refrain from clicking on the wrong spots, as each mistake lowers your remaining time by 5 more seconds. Employ your observation skills to increase your score and conquer all levels.
