To make the Christmas party more exciting. Santa has brought a lot of gifts, but all gifts are just air balloons. Balloons with numbers. But when balloons raise to the ceiling, they may arrange the BlackJack sum 21. So, delete all extra balloons, to ensure the Black Jack sum on the remained balloons and receive the fantastic reward from Santa's Granddaughter. Yes, she is beautiful, and she knows how to cheer you up!
