Teen Patti Casino is a gambling card game that originated in India and became popular in South East Asia. Teen Patti Casino is somewhat similar to poker and uses three cards, and is very similar to 3-card poker and 3-card brag with some minor differences. Before playing Teen Patti Casino is necessary to agree the value of the minimum stake (which I will call one unit). Everyone places this minimum stake in the pot - a collection of money in the centre of the table, which will be won by one of the players. The dealer deals out the cards one at a time until everyone has three cards. The players then bet on who has the best three card hand. Each has the option to look at their three-card hand before betting (playing seen) or to leave their cards face down on the table (playing blind).

The Teen Patti Casino game starts with one of the players dealing the cards. The cards are usually dealt anti-clockwise. Before starting the Teen Patti Casino game, usually an agreed number of card(s) is/are picked or dealt to decide the dealer for the opening hand. Each player may be required to put up an ante into the pot before picking/dealing the card(s). The winning player gets the pot. The relative rankings of the card(s) may also decide the seating arrangement for each player. This entire process is called cut-for-seat.

Loose and tight in teen patti refer to a player's general tendency to play hands beyond the first round or to fold them quickly. There is no commonly-accepted threshold in terms of a ratio or percentage of hands played, but a "tight" player will often choose to fold weaker hands, while a "loose" player will bet on more of these hands and thus play more hands to the show/showdown.
