Begin the game by selecting the 'Play' button. Search carefully through the festive vehicle images to spot the hidden keys. Each level demands you to find 10 keys concealed within the image. Navigate through 6 different challenges to complete the game. Remember that the time is limited, so hurry to find all keys before time ends. Refrain from clicking on the wrong spots, as each mistake reduces your remaining time by an additional 5 seconds. Use your observation skills to enhance your score and conquer all levels.
