Slot machines evolved over time, and the Evolution of Slots keeps going. After the first slots gaming machine was produced, several variations of the machine were made. Operating the slot machines became much quieter and in the early 1900’s other symbols were introduced into the slot games. Some games began using cherry symbols along with other fruit-themed symbols, and it was around this time the slot machines began to be called “slots”. Today, the cherry slot machine games still remain popular to this day.

During this period of American history, gambling was banned across the United States. But it was later reintroduced, and this is when slots began to dominate the floors of gambling houses and brick-and-mortar casinos. It has been suggested that the women would play on the slots while their husbands, who were high-rollers, would play in more serious card games.

A company called Bally’s was credited for making the first electro-mechanical slot machines, which were invented in 1963. The machine was unique for its time in that it was motorized by electricity and had sound effects. This was the first slot machine of its kind to incorporate a coin hopper, a container where the coins are dispersed so the player could immediately receive their payout.

By 1970, machines with a bigger hopper were being developed so that bigger payouts to players were made possible. During this time, Bally also brought on board a computer programmer, Inge Telnaes, to program the slots so that it was possible for the machines to offer bigger payouts whilst not dropping the payout percentage of the machine by incorporating more reels, more symbols, and larger bets into the games, so the slot manufacturers were still making the same amount of income.

These electronic slot machines led to the demise of what was dubbed as the “one arm bandit” slots, as they used buttons instead of levers, and now many of them now also have touchscreens.

The video slots came into existence in 1976. It revolutionized the slot machine world at the time, although the pioneer video slot machines were enormous in comparison to today’s slots, as computers were nowhere near as powerful back then and they took up a lot of space. After some early success the machine was bought by IGT, a major slot machine manufacturer. The most famous video slot is Buffalo Slot Machine.
