You’ve probably heard the phrase “lucky number 7” both inside and outside the casino, but have you ever wondered what it is that makes number 7 so lucky? Have you ever thought about how you could possibly benefit from that luck when playing at a land-based or online casino? Regardless of whether you believe in luck when playing classic games such as poker or spinning the reels, chances are you’ve looked into the number 7 and how it could possibly impact your gameplay or increase your chances of walking away victorious.

Read on for the details about the origins of the lucky number 7 in different cultures and how it applies to live dealer casinos and various online slots and which online casino games take gamblers’ emotional attachment to the number into consideration to create more enjoyable and exciting gameplay.

Why is seven a lucky number?

It’s a prime number (which means it can only be divided by itself and one) and it appears everywhere. There are seven days of the week, seven continents, seven seas, seven notes on a musical scale, seven colors of the rainbow, Shakespeare’s seven ages of man and Snow White’s seven dwarves.

There’s also plenty of religious significance attached to the number. In the Bible it’s said that God created the world in six days and rested on the seventh – and so, for many Christians, the number represents a sense of “completeness.” In the Jewish culture and religion, there are believed to be seven heavens while those who follow the Islamic faith and who make the pilgrimage to Mecca are required to walk around the Kaaba seven times. From this, it’s evident that the significance of the number 7 dates back hundreds of years, which means that the psychology of its meaning is rooted much deeper than one might think. Once something becomes entrenched in everyday life and belief, it becomes extremely difficult to change and make people think about it in a different way. That is the case with the number 7 and the role it plays in online blackjack live dealer games, slots and other casino games. 

Most experts think that the reason why the number 7 is considered “lucky” is simply because of its many positive associations. Obviously, there’s no concrete proof that the number has any real influence when it comes to scoring big at the casino or regarding anything else in life, for that matter. Having said that, most people have their own lucky number, and if yours happens to be number 7, then you’ve got a long history to back you up.  

Number 7 and online slots

Due to its association with good luck and fortune, it’s unsurprising that the number has infiltrated the world of online slots and casino slot machines. You’ll often see the “7-7-7” winning combination mentioned, as well as the number 7 appearing as a traditional slot game symbol – often representative of the most impressive prizes the game has to offer.

When it comes to the number 7 and gambling, it is widely believed that it’s the fairest number to predict. In other words, the fairest chance of winning and losing is said to be by guessing a number between one and seven. You could take it a step further and say that just as the number represents completion, perfection and a full cycle in other aspects, the same can be assumed in gambling as well.

By keeping this in mind when spinning the reels and playing online slots for real money, some believe that it may give you an added advantage because you’ll be more likely to predict the cycle of cards or spins – depending on which casino games you prefer.
