For "How to play casino war game?", much depends on which kind of poker is meant. Poker at a casino comes in two very different forms. In house games such as three card poker or casino hold'em, each player faces the dealer and a paytable. In room games such as hold'em or Omaha, players compete with each other and the casino takes a small cut of each pot. The hand rankings are shared by all of them, and the other rules vary from game to game.
House games and room games reward different things. In a house game the best strategy is fixed and printed in guides, and the long run result depends on the paytable. In a room game, skill against the other players decides the outcome over time, and the rake is the only certain cost. Knowing which kind a table belongs to, before sitting down, explains whether a strategy chart or practice will help most.
Three card poker deals three cards to the player and three to the dealer. After an ante, the player either folds or places a play bet equal to the ante. The dealer needs a queen high or better to qualify; if it does not, the ante pays even money and the play bet is returned. An optional pair plus bet pays on the player's own hand, whatever the dealer holds. Standard advice is to play any hand of queen, six, four or better.
The order climbs from a high card through pairs, trips, straights, flushes, full houses and quads to the straight flush, though three card games place a straight above a flush.
