Each player starts with five cards you'll eventually arrange on a 3 by 3 square, and you flip a coin to see who goes first.

The cards are mostly of the monsters and whatever else here in this world, so I found it pretty helpful for learning them all. There's various numbers on the cards for toughness and stuff. When the card gets put down, any cards next to it you have to figure out whose numbers are higher. If it's higher, then it wins and the lower card switches to the other side.

Then at the end, whoever has the most cards on their side wins.
