How to play: Just pick up a card and start comparing the five images on it. Look closely at the four varied images and find the differences. Use the process of elimination to figure out which one is the original. It's a race against time and your friends if you're playing together. Attention: Keep the cards away from water and sharp objects to avoid damage. Maintenance: Store the cards in a dry and clean place. If they get a bit dirty, you can gently wipe them with a soft, dry cloth. Have fun playing and training your observation skills!
