History of Slots

In 1891, Sittman and Pitt created the first gambling machine, which was card-based; however, the first coin-operated gambling machine was created in 1894 by inventor Charles August Fey with picture symbols and reels. In the late 1940s, slot machines started gaining popularity in Las Vegas.

The rest of the world followed suit, and places such as Europe, Africa, Asia, and the Caribbean opened casinos. The 1970s was when the video slot was born, which was the predecessor to today’s slot games.

Online casinos first hit the digital world in the 1990s, and online slot games were born. You can equally play this in online casinos like in German online casinos, European Casinos or in your favorite available online casino.

Mobile slots made their breakthrough in the 2010s. The popularity of slot machines has not decreased, and if anything, they are more popular than ever!

Transition to Online Slots

Land-based slots originally were chunky with big arms to pull to spin the reels. In the 1990s, when online slots first entered the market, they didn’t have many features and were pretty basic. In 1996, video slots started offering bonus rounds, and this is when online casinos exploded with bigger winnings on offer, and more and more players started turning to online casinos.

  • The first online gambling venue was Liechtenstein International Lottery in 1994
  • The first online casino launched in 1996 by Intercasino
  • The first progressive online jackpot was Cash Splash, launched in 1998

Top 5 Online Slots Myths

There are myths in any industry, and the online casino world is no exception. Most of these myths are misleading and false. We will help dispel some of these common myths in order for you to make informed decisions with the correct and accurate information at hand. Many of these myths originated in land based casinos. Listed below are some of the most common myths you will hear today about playing slots online.

1. Online Slots Are Rigged

All slots come with Random Number Generators (RNG), which means that each spin is independent of the last. These are tested regularly and there are very strict and heavy regulations in place. Developers and providers are continuously working hard to earn players’ trust and to offer a fair gaming experience.

2. Slot Machines Can Run Hot or Cold

Again all slots have strict regulations to ensure fairness and the Random Number Generator ensures that each spin is independent. Every outcome is entirely random, and just as you could hit 2 bonus rounds in a row, you could also go many spins without one.

3. You Win More Often With Play Money Games

When testing a slot with play money, the same rules apply as with real money. Each spin is independent, so you can experience both losing and winning streaks, just like with real money.

4. The Games Crash When You Are Winning Too Much

The game will not have crashed due to you being on a winning streak, it would have just been bad timing that it happened to crash when you were winning. All your spin details and winnings will be available for the operators to rectify if this happens.

5. Online Slots Pay More Than Live Slot Games

The best online casinos have worked incredibly hard to ensure good reputations, and the Live Slot Games will have the same RTP statistics. They will be controlled and regulated strictly to ensure complete fairness and transparency when playing. You are just as likely to have a big win on a live game as you are on an online slot game.

Benefits of Playing Online Slots

Playing slots within your financial means can be a very enjoyable experience. With so many choices and the chance to have a big win, it can be a thrilling, exciting, and fun experience. With strict regulations in place, you can be guaranteed a fair and safe gaming experience.

  • Wide Game Selection: Some slots are what they call high variance, meaning they will pay out less often but larger, whereas low variance pays out less often. With so many slots to choose from, you will find your favourite in no time.
  • You can play On The GO: We all own mobile phones and tablets, and they are always with us, so whilst you are on the train travelling somewhere or just down the park or beach, you can still access your favourite online casino.
  • Easy and Fast: The beauty of online casinos is how quick it is to create an account, navigate your way around the site, and play games in no time!
