All slots games

While the exact origins of slot machines can be hard to pinpoint, they can be traced back as far as 1891. Sittman and Pitt - a gaming company, based in the USA - started to manufacture a slot machine of sorts, and it included a 5-reel drum and real playing cards to deliver the action.

It was also the first slot to utilize the popular ‘one-armed bandit’ mechanism, which allowed players to input a physical coin and pull a lever to play.

1964 was a reasonably monumental moment in the development of the game once more, and this was when the first electronic slot machine was developed. It was called Money Honey, and it was produced by a company known as Bally - a company that are still churning out free slot machines and UK online slots today.

Video slots, as we know them today, were first released in 1976, when a company called Fortune Coin started displaying the results of their slot machines on a large 19-inch TV screen located within a casino’s floor. It was first available at the Hilton in Las Vegas, and it proved popular.

Of course, in the 1990s (when online gambling was starting to take off), video slots in the form we see them today started to appear - and this is when many of the big game developers started cropping up in the iGaming market.
