Other rules, like the need for a minimum number of melds or particular scoring schemes, are introduced by variations like Indian Rummy & Gin Rummy. A gambling game that places a strong emphasis on betting and bluffing is Teen Patti, also known as Indian Poker. A standard 52-card deck is used for play, and three to six players are usually involved.
