Background Info: From Liberty Bell to Money Honey

Let’s start with a bit of history. It all began in 1891 when a San Francisco mechanic Herbert Miller invented a basic slot machine he called “Three Card Draw.” Later on, another Californian, Joseph Pulizzi, improved it and named the new game device “Operator Bell.” Its main feature was that it paid off depending on how much the player had wagered. In 1895, another West Coast inventor Charles Fey created a simplified version of the slot machine called “Liberty Bell.” This three-reel game featured a logo of a bell, a horseshoe, and a diamond/spade/heart symbol. It brought a payoff when three identical symbols lined up.

The first half of the 20th century was very productive in terms of innovations in this area. In 1902, Joseph Pulizzi introduced a slot machine called “Operator Bell,” while his rival, Herbert Milller, came up with “Trade-Off”. In 1907, another famous one-armed bandit saw the light of the day; Charles Fey’s “Liberty Bell” featured a soup-to-nuts win of 50 cents. The company named “Classic 243” produced the first electromechanical slot machine, “High Hand” in 1964. It was characterised by a wide variety of features such as a bonus round, multiple lines, and symbols. In 1976, Roger Tam invented the first video slot machine, “Fortune Coin Company's ‘Video Poker’," featuring a screen, a CPU, and a random number generator. The story went on with the launch of “Video Slot Machine Category” in 1978 and the first electronic roulette machine in 1979. IGT (International Game Technology) has released “Video Slot Machine ‘Megabucks’” in 1986. This iconic slot is responsible for the largest number of winners who have scooped numerous jackpots totalling millions of dollars. It provided the biggest ever win of $39.7 million hit by an anonymous Las Vegas resident in 2003. Another groundbreaking invention by IGT was “Wheel of Fortune Video Slot Game” launched in 1996. It became so popular among American players that it ranks as the top-grossing mechanical trade show exhibit of all time!
