Like I mentioned earlier it also took me a while to figure out Triple Triad but it and Tetra Master are basically the same thing except Tetra is easier to figure out in the beginning since I got it by my second game. In Triad the strongest numbers facing each other win, while in Tetra its the arrows that point on the side. So simply in Triad all you need is a card with high numbers to face a card with a lower number on the two sides that connect. In Tetra get a card to face another card with one of your arrows facing toward an opponets empty space. That should make it easier to understand.
