The Patcard value is determined by supply and demand. Once a Patcard is created Patboy will set the index price which is the value with which the Patcard will enter the Market. After it's sold to a Patplayer the value will grow each time the Patcard get's sold to another Patplayer for a higher price obtaining the value of the price that was paid for it. Patcards are bought with Patcoins. Players can earn patcoins in the Game when they solve Puzzles. Patcoins can only be used in the Patboy Card Game and are a Game Valuta only.
