777 is used on most slot machines in the United States to identify a jackpot. As it is considered a lucky number, banknotes with a serial number containing 777 tend to be valued by collectors and numismatists. The US Mint and the Bureau of Engraving and Printing sells uncirculated 777 $1 bills for this reason.

* Jackpot World Casino does not offer real money gambling. It is intended for an adult audience for entertainment purposes only. * Practice or success at social casino gaming does not imply future success at real money gambling and gaming.

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.
