Players must quickly memorize card positions, flip matching pairs, and clear 6 increasingly difficult levels to test the limits of their concentration and memory. After completing all levels, the game evaluates your performance and calculates your personal Brain Age, based on completion time and mistakes. 玩家需要在有限的時間內記住卡片的位置，翻出相同圖案的配對卡片，並在 6 個循序漸進的關卡中挑戰自己的大腦極限。 遊戲會根據你的通關時間與失誤次數，計算出專屬的「腦齡（Brain Age）」，讓你在輕鬆遊玩中也能了解自己的反應與記憶能力！
