It's not hard to learn in the beginning, because there are fewer rules to contend with. Read up on the tutorials before you start. And don't worry if you don't understand the rules for 'Same', 'Plus', etc.... I don't- and I usually eliminate those rules anyway (except on the Space Station-ugh!).

Just be forewarned, if you're want to collect every kind of Triple Triad card, it's going to take hours.

Of course it's nice to look over a complete card collection.

Just save between trading important cards and reset if you lose the card.
