Teen Patti ("Three Cards" in English) is a card game that originated in India and became popular in Southeast Asia. It 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. It is immensely popular in India and is also referred to as Flush or Flash.

3 Patti uses a standard 52-card deck, with Aces ranking highest and 2's lowest. The object of the game is to have the best 3-card hand, and to maximize the pot before the showdown. Any hand of a higher category beats any hand of a lower category. Any reasonable number of players can take part and it is probably best for about 4 to 7 players.
