In Satta Matka, a player selects a set of numbers from 0-9, and the result is determined by drawing three numbers in different sets. For example, if a player chooses the numbers 3, 5, and 7, the result is calculated by adding them up to get 15, and the final number is the last digit of this sum, which in this case is 5.

While Satta Matka was initially played offline, it has now moved online, and there are many websites that offer Satta Matka games. However, it's important to note that gambling is illegal in India, and participating in Satta Matka can lead to legal consequences.
