Dream11 has a very basic business model. It allows you to choose a team based on your preference before the match starts. Based on their performance during the actual match, you accumulate points and get a rank at the end of the game. If you participate in a game with money, it goes to a common pool, and you get winnings based on the ranks after a service fee is charged.
