The Slot Machine Boom
After Mill introduced the more compact slot machines, they started spreading rapidly. You could find slot machines in almost every saloon. These early slot machines were loud and could only be operated by pulling the arm to spin the reels. This all changed in 1964 when the first slot machines that used micro-processors to determine the outcome of the game were introduced. This invention made slot machines more secure which allowed operators to offer bigger prizes. This is when large jackpots starting being offered to slot players. This immediately increased the popularity of slot games and attracted a lot of newcomers hoping to win a massive jackpot. After all, there is something very enticing about the knowledge that a single spin of the reels could be your passport to life changing sums of money.
