Launch the game by clicking on the 'Play' button. Scan carefully through the holiday vehicle images to find the hidden keys. Each level demands you to find a set of 10 keys within the image. Move through 6 different challenges to complete the game. Remember that the time is limited, so act quickly to find all keys before time ends. Steer clear of clicking on the wrong spots, as each mistake lowers your remaining time by an additional 5 seconds. Use your observation skills to increase your score and finish all levels.
