Photos are displayed on both screens. You must select the areas on the bottom screen where you see a difference and find all differences in a limited amount of time. If you manage to discover the differences within the time limit, you'll be rewarded with Cups according to your performance. There are Bronze, Silver and Gold Cups to be won. The game features 160 different photos from established photographers, with more than 1,000 combinations of differences to find in the images. Choose between one-player and multiplayer modes. The multiplayer mode is a turn-based mode in which each player must spot the differences in the same image.
