Essentially the same as the kids' card game, except with opportunities to wager and win. First place a bet on the next game; you can also place an additional bet on a tied outcome which pays at 10x the bet.
Once you've finished wagering, hit DEAL near the center at the bottom of the display. Player and dealer will each get one card face up; higher card wins. In cases of the same denomination card, there will be a "war" in which another card is flipped up. Winner of this faceoff takes all the cards in play for that turn.
