TeenPattiStar is a 3-card poker game based on the Indian card game of the same name. The game is played with a standard 52-card deck, and you can play it online with your friends.
The gameplay is very simple: you get a hand of 3 cards, you need to decide what you want to do with them, and then you choose one of the three options.
The options are:
Keep the cards: this option is the default one, in this case you will get a new hand.
Flush: you will get the cards that have the same rank, but they will not be in the same suit.
