The Triple Triad Card Game is a slight diversion to the main action of the actual game.  It is easy to learn, and challenging to master, and that's what makes it so fun. 

The rules are simple.  You use 5 cards in a game, placing them on a nine spaced board. The numbers on the cards represent the power of each side of the card.  For example: 
The Odin card on the left defeats the Cerberus card because Odin's top number 8 is stronger then Cerberus bottom number 5.
So if a stronger number meets a weaker number, the weaker card gets captured by the stronger opponent.  Of course, every card has its weaknesses.

To gain cards, there are 3 ways.  First you can gain a card by winning a card game.  Secondly, you sometimes recieve cards when you win a battle.  Thirdly, you can morph monsters into cards by using the GF Card Ability.

You can also use a GF ability called Card Mod.  It lets you refine cards into rare items, which is essential for weapon upgrades.
