A brief history of slot games

Online slots may at first glance seem limited to online gaming, but the original version, like any casino game, was indeed a physical game.

The very first slot game originated in New York in the late 19th century. The original version was a mechanical machine with five drums, which displayed different playing cards when a lever was pulled.

The game was based on poker: the player would insert coins and spin the reels, trying to score a high poker hand. The machine would then give out prizes such as cigars and beer vouchers - in fact, most of these machines were installed in pubs and bars.

This machine eventually evolved into the Liberty Bell machine, which replaced playing cards with a selection of symbols - many of which we can recognize in modern slot games, including the Liberty Bell itself: horseshoes and hearts! The game quickly became incredibly popular and was soon installed in gambling establishments around the world.

The next type of slot games came along with Money Honey, which was completely electromagnetic, invented in the 1960s, and followed by the first video games in the 1970s. And once the internet was fully established, online video slots also took off - now one of the most popular forms of online gambling in the world.

What do the best online slots consist of?

A new online slot machine is not obviously always just a hit. There is a lot involved in ensuring that online slots leave a positive impression on the average gambling enthusiast. Hence, at Casino777.nl, we pay a lot of attention to quality. We are committed to offering only the best online slots of the moment. And to ensure this, we take into account the following features:

  • Strong theme: First of all, a strong theme is very important. This is because modern casino games have to offer more than was the case until now. Whereas the traditional fruit machine was enough to attract a large audience for many years, this is long gone nowadays. The average player has higher quality requirements. For example, when it comes to the overall theme of the game. Thereby, a slot can go in any direction. From an underwater theme and a space theme to a pirate theme and a candy theme. There's definitely something for everyone at Casino777.nl!
  • Convincing animations: On top of that, a lot is also possible today in terms of convincing animations. Think of a visually tantalizing animation the moment you make a big win. Nothing beats the feeling you experience then. The combination of the right images and a nice sound then keep it fun to keep playing again and again. So be sure to check out how a casino game scores in terms of animations for long-lasting gaming fun.
  • Interesting bonus rounds: Perhaps the most important part of the best online slot games; the bonuses they have to offer. Indeed, with most games, the biggest wins are to be had in the bonus rounds. Think of special theme-related bonuses, Free Spins, and even unique jackpot rounds. The very best online slots make you jump for joy when you activate the bonus round. Purely because you know this is synonymous with big wins.
  • The best software: At the same time, the underlying software of the casino game plays a crucial role. This is because a good online slot consists of the best, most modern software available.

And that remains one of the most important advantages of this type of casino game. You leave your worries behind for a while and immerse yourself in the virtual world. With a bit of luck, you end up with a nice profit too.
  • Responsiveness: Finally, the best casino games should meet one more important requirement; complete mobile-friendliness. After all, nowadays the average casino lover often enough chooses to navigate to the online casino on their mobile. What you definitely don't want then is for the game not to adapt to your screen size. This causes a huge amount of inconvenience and frustration. Therefore, the best slot games are the most accessible ones. This way, you always have a free choice to start a game on your mobile or just on your laptop or computer.
