Four types of skill cards: 3 Cards You can flip three cards instead of the usual two, giving you an advantage early in the game. Darkness Hide the images of cards your opponent has flipped, confusing their memory and strategy. Shuffle Reset the position of memorized cards, disrupting your opponent’s plans. See through View the image on a specific card, giving you the information you need to make a perfect match. This game was inspired by the developer’s experience playing Concentration with their child, who came up with unique ideas like, “What if you could flip three cards?” or “What if you could see through the cards?” By turning these ideas into reality, the game offers simple rules but deep strategic gameplay.
