Today, X is the best-selling board game in the world, sold in 103 countries and produced in 37 languages. It was developed in 1934, the height of the Great Depression, when Charles B. Darrow of Pennsylvania, showed what he called the X game to the executives at Parker Brothers. Can you believe it, they rejected the game due to "52 design errors"! But Mr. Darrow wasn't daunted. Like many other Americans, he was unemployed at the time and the game's exciting promise of fame and fortune inspired him to produce the game on his own. With help from a friend who was a printer, Mr. Darrow sold 5,000 handmade sets of the X game to a Philadelphia department store. People loved the game! But as demand for the game grew, he couldn't keep up with all the orders and came back to talk to Parker Brothers again. The rest, as they say, is history! In its first year, 1935, the game was the best-selling game in America. And over its 65-year history, an estimated 500 million people have played the game of X!

   Over 200 million X games have been sold worldwide.

World records are maintained for the longest game in a treehouse (286) hours, Underground (100hours), in a bathtub (99 hours) and upside-down (36 hours).The longest  game ever played was 1,680 hours long. That is 70 straight days!

In Cuba, the game had a strong following until Fidel Castro took power and ordered all known sets destroyed.
