Duad is a single player or multiplayer matching card game. Every pair of cards has only one symbol that matches between the pair. Find the matching image between your card and the center card, tap the matching symbol on your card, watch your card move to the center pile, and repeat this process as many times as you can. In the single player mode, you have 45 seconds to find as many matching symbols as you can. In the multiplayer mode, you compete to be the first player to reach 10 points. Gain a point for each correct match, and lose a point for an incorrect match. 2 players are supported on an iPhone, and up to 4 players are supported on an iPad. Duad helps with cognitive development since players must quickly process images, remember which images are on each card, and identify the matching image between cards.
