Andar Bahar

Introduction

Andar Bahar is a simple card game, said to originate in southern India, and has since spread all over India and now Internet casinos. Read on for the rules and analysis.

Rules

There are variations of the rules so I will endearvor to explain how the game is generally played and mention which rules are fundamental to the game and which are optional side bets.

  1. A single 52-card deck is used.
  2. The two main bets are Andar and Bahar.
  3. Before the first card is dealt, the players may or may not be able to make side bets on what it will be. Possible bets are on the rank or suit of the first card.
  4. The dealer shall deal the first card and place it in the middle of the table. If there were side bets based on that card, the dealer shall adjudicate them. This first card is sometimes known as the "joker," which I know is confusing. This first card is not wild and has nothing to do with the card generally referred to as a "joker." I prefer to call this card as the "Middle Card," to make explaining the game easier.
  5. At this point the player may make an Andar or Bahar wager. There may also be side bets on the total cards to be dealt after this point, for example the 20+.
  6. After bets are made, the dealer will deal cards one at a time until he gets another card matching the rank of the Middle Card. The dealer shall alternate placing cards on the left and right of the Middle Card. In some versions, the dealer starts on the left side of the Middle Card and in others he randomizes it, based on the color of the Middle Card. However, which side the dealer starts on does not matter.
  7. If the total number of cards dealt after the Middle Card is odd, then the Andar bet shall win. Depending on the version, the Andar bet may pay 0.9 to 1 or 0.95 to 1.
  8. If the total number of cards dealt after the Middle Card is even, then the Bahar bet shall win. Depending on the version, the Bahar bet may pay 0.95 to 1 or 1 to 1.
  9. After the Middle Card is matched, any side bets based on the total number of cards dealt after the Middle Card shall be adjudicated.

Andar and Bahar Analysis

The following table shows the probability of all possible total cards dealt after the Middle Card. The middle column shows the probability of exactly that number of cards. The right column shows the probability that the total number of cards will be that number of less. For example, the probability the probability of exactly 20 cards is 2.2329% and the probability of 20 or less cards is 78.4154%.
