Once wagers have been placed, the Player and the Dealer will each receive a single card when the Deal button is pressed. If the maximum amount for a wager is exceeded, the wager will be cleared. Before cards are dealt, these wagers can be withdrawn by pressing and holding the spot for a brief moment. Tapping on the Ante or Bonus spots will increase the wager by the default amount ($5, $25, $100) that is defined in Preferences. The maximum amount of the bonus wager is $100. This bet is won if the value of the Player's first card matches the value of the Dealer's first card. There is also an optional Tie Bonus wager. This wager may be from $5 to $500 and is paid if the Player wins the hand.
The game begins by placing an Ante wager. Cards are ranked as in poker, except aces are always high. If the cards are the same (a tie), then a war begins. It is played heads up, Player against Dealer, to see who can get the highest card. Casino War is a game most folks played as children.
