The Referral System[]
You can refer people to the game by sending them your personal referral link that you can find on the refer page. If they visit the site using your personal referral link and they sign up to the game, they will then be known as your underlings. You get 100 turns for each of your friends that you refer who registers at gangstermind.com. You get 3$ in real cash for each one of your friends that you have referred who buys turns.
