Less commonly used nicknames for the game of 21 include Pontoon and Van John. Both arose in the South, probably around illegal casinos in New Orleans. Both nicknames probably are corruptions of the pronunciation of the French game vingt-un, which means "21" and is believed by some to be a blackjack forerunner. Others believe there are closer connections between blackjack and the Spanish game uno y trente, the Italian game baccarat and a much older Italian game called 72. Horizontal gaming wheels, such as those used in roulette, were invented in England in 1720 for a game called roly-poly. Roly-poly was similar to roulette, except there were no numbers on the wheel. There were alternating white spaces and black spaces, along with a "bar black" space and a "bar white" space. The "bar" spaces were the equivalents of zero and double-zero -- if the ball landed in either space, bets on black or white lost. Roly-poly was banned in England in 1745, but the horizontal wheel traveled well. By 1796, modern roulette was being played in France. The kings in decks of playing cards represent real leaders and conquerors from history, although not all had the title of king. The deck we use today is based on cards designed in 15th-century France. The king of spades represents the Biblical King David, the king of clubs represents Alexander the Great, the king of hearts represents Charlemagne and the king of diamonds represents Julius Caesar. The four suits represent civilizations that have influenced our culture. Spades represent the Middle East of Biblical times, clubs represent Greece, diamonds represent the Roman Empire, and hearts represent the Holy Roman Empire.
