At the end of that century, after the French Revolution was over in 1789, Black Jack reached America, soon to become one of the favorite gambling games there. In the United States, Black Jack was preferred by professional gamblers who knew how to manipulate the odds and the bets. At the beginning of the 1800s, there were no government regulations on gambling, and thus Black Jack flourished. By the year 1919, special green-felted tables used in Black Jack today had been introduced, and a decade later the game was already the third most popular casino game after Roulette and Craps. At the end of the fifties, Roger Baldwin organized basic Black Jack strategies applying mathematics and the game reached first place among the most popular gambling games.
