To start, you're dealt one card at a time and it's your job to place each card in one of three potential poker hands. Once you fill a hand with five cards, you score points based on the hand and it disappears to make room for the next one. The better the hand, the more points you score.
Every time you make a good hand, a corresponding box in the poker tower will light up. If you're able to light up the entire tower, you're rewarded with higher point values across the board that will lead you to even higher scores. The strategy needed to light up the tower may take a few games to become clear, but the rewarding aspect of the game is in the tricks you pick up with every game you play.
