Trifecta

A portable game for two players. Players take turns adding one card at a time to either one of their or one of their opponent's three rows. Each row has certain restrictions to it that determine where a card can be placed. Some cards however can change these rules and either make it easier for yourself or harder for your opponent to complete a row. If the total value of a row after five cards are placed is 21 - 26 inclusive, the owner of that row gains a point. If not, the row is emptied and owner gains nothing.
