Not enough time to take out a card deck, but you still would like to play for a bit? The Battle is perfect for you. In this version of the classic game “War”, you and your opponent begin with a deck of card. Then you confront at each turn a card taken from the top of the deck. The player who has the strongest card takes them all and if the cards are of the same strength, then it’s time for the “Battle”. You put a first card face down over the first one, then another one face-up.
