Slot machine myths

In the slot machines' world, just like in any other sphere of human activity, there are some myths about online slots games. They are mostly groundless, but sometimes people are taking them for facts. There is a list of most famous ones down below:

You can only win if your bet is small, the computer blocks the big wins. It isn't true.

The computer, of course, distinguishes the size of different bets, but it works on the RNG principle, so it cannot change the result, no matter how big is the bet.

Any slot works following a certain algorithm. All online slots have a payment table, where one can see the size of multipliers. The game screen has the information of the bet per line and the summary bet. After a win, the slot shows the sum of the win.  So, by paying attention to the payments' table and gaming process on best online slots to play, you can determine the optimal bet size. The bigger it is the bigger is the win. But consider your deposit when raising the bet.

By placing the bets by a certain scheme, you can win a prize.

The truth is, there are some strategies that work in cards' and other games, but not in the online and offline slots because they are working on the RNG principle. You can't change the way the slot was programmed.

Any scheme can work only in terms of bet's proportions. For example, lowering the bets after losing and increasing after winning. The thing is that you're risking the money you've already won and lowering your losses.

Playing online is more profitable than offline.

It's not true, because all slots real money are based on the same RNG, so there is no difference where to play.

The history of the 1920s

After the first World War, the world was enjoying its normal peaceful life. No one expected for Great Depression and World War II to happen. The USA was dominating in the financial sphere, and the business was blooming in the big cities, though there were problems like the criminal and criminal wars. At the beginning of the age, Chicago was making the whole America shiver due to the big number of criminal groups; and this time was depicted in different books, movies and video games.

In the end of the 19th century, a lot of Italians came to the USA. They brought both cuisine and mafia into America. Many of famous mafia families' members came to the USA and started their own criminal groups.

Chicago Outfit

Italians were making business, opening underground casinos and totalizators, committing various frauds. Al Capone lived in the Chicago, though he wasn't the biggest mafia boss in the USA. One more legendary criminal group of that time was the Chicago Outfit with Toby Accardo as a leader.

Johnny Torrio was also a part of this syndicate, and even though Al Capone became way more famous than he did, Torrio put forth the idea of the National Crime Syndicate.


In 20s Chicago Outfit was well-known for its being sanguinary and causing violence on a large scale. In 1926 the number of their victims was about 75 — and that's in one year! It still stays the largest and powerful mafia groups of USA; the only group to compete with it is was the Genovese crime family.


Comparing to other slot machines made by Austrians, this slot stays as the most non-standard one. You can't really compare it to the NetEnt's slots, because it's made according to the Novomatic’s schematic patterns; nonetheless, the Chicago slot has its own interesting charm, which brings a pleasant variety in the lines of monotonous fruit-machines.
