Played with a simple 52 card deck with a total of 6 decks in the stack. Place your wager and get a card, the dealer deals their card. If your is higher in value (the ace is high) but the others face cards are all equal values, then you win over the dealer. When the cards between the dealer and the player you can either surrender your hand and give up half of the bet you placed or decide to go onto the war round. It’s that simple. Once you go to war you have to place a bet that is the same or higher when you started the game. After the next card hand if you win higher against the dealer then the original bet is the (push) or an even bet but still gets the payout raise on the new bet placed. Therefore the bet place of double will pay out only half if you win, if you lose it goes back to the dealer.
