The actual amount of money in the jackpot is the "cash value" advertised by the lottery, and it comes from a portion of Powerball ticket sales.
But do note that Jackpot World is not a real casino and that you can never cash out your winnings in the game. Winning 12,000,000 coins in the game does not mean you win 12,000,000 dollars. The game is purely for entertainment purposes.
