They started off as a small mechanical device meant to entertain, but over the years they have transformed into highly advanced and technologically advanced online slot machines. The first slot machines were known as one-armed bandits and were invented in the late 19th century by mechanic Charles Fey. These machines would usually have three reels, a single pay line and a lever located at the side that the player could pull to spin the reels. Players would insert a coin into the slot and if they lined up a winning combination of symbols on the pay line they’d receive their winnings in the form of coins. The one-armed bandits were a hit in Europe, especially in the UK.

They started appearing in casinos and would often differ in looks and features but the same fundamental principle would remain the same. As the popularity of slot machines grew, manufacturers began to innovate with more features and higher payouts. The next step in the evolution of slot machines came in the form of video slots.
