Casino War is a simple card game played between players and the dealer, typically using a standard deck of 52 cards. Each player places a bet, and both the player and dealer draw a single card. The higher card wins, with ties resulting in a "war." In a war, players can double their original bet, and a second round of cards is drawn. The game is fast-paced and easy to understand, making it popular in casinos. Its straightforward rules and quick gameplay attract both novice and experienced gamblers alike.
