Dice The six-sided dice have a fascinating history. Traditionally carved from animal bones, they have been used by man as a means of predicting the future as well as the outcome of games of chance. These lucky cubes have been fashioned from all kinds of materials ranging from fruit pits, ivory, jewels, and even human teeth. The oldest known dice were uncovered by archaeologists in Iraq where they were possibly used with a game similar to the modern game of backgammon. These dice were made from baked clay and are approximately 5,000 years old. Slot Machines Slot machines have been with us for over 100 years with the earliest version attributed to American Charles Fey. Fey devised the first slot machine in San Francisco in 1899 and it comprised a three-slot device containing an image of the famous Liberty Bell, a well-known symbol from the American Civil war. In fact, Fey's machines were so popular that for many years slot machines were called Bell machines. The bar symbol, which is the other classic slot machine design, is derived from the logo of the Bell Fruit chewing gum company. The gum was delivered through slots in a machine designed by Herbert Mills of Chicago in 1910. The use of fruit symbols is also linked to the Mills machine as these represented the different gum flavors produced by the Herbert Mills company. The fruit flavors gave rise to the other common name for these devices - fruit machines.
