Satta King is a popular but illegal lottery and gambling game in India. It originated from betting on the opening and closing rates of cotton, which later evolved into a number-based lottery system. The game involves choosing a number between 00 and 99, and if the selected number matches the declared result, the player wins a significant cash prize. Satta King has multiple variants, including Gali, Disawar, and Faridabad, each with different result timings.
