Casino slots are one of the most popular games offered by online casinos. Many casinos out there offer hundreds of slot games to try your luck at. All casino slots are not made equal. It's essential to understand how they work before you venture into the world of casino slot games.

The Inner Workings of Casino Slots

Generally, online casino slots operate in pretty much the same way as the slots in actual casinos. However, since an online casino's overhead cost is a lot lower compared to a real casino, it can afford to provide games with higher winnings to players. Online slots also have the benefit that online casinos bring, which include special bonuses and impressive graphics to draw you in. 

Random Number Generator (RNG)

The magic behind an online slot machine is really the code of the random number generator. Licensing authorities ensure fairness is upheld at all times by regulating the software that is in charge of this randomness. 

RNGs operate by continuously generating thousands of numbers between zero and approximately four billion. Pressing the spin button on an online casino slot game produces a random number at that exact moment. This number will correspond to a particular result on the reels of the game.

A casino slot does not have a memory of the random numbers it comes up with. A slot game that recently paid out a jackpot will still have the same odds of hitting that jackpot on its next spin. This is what truly makes slot machines fun. 

Return to Player (RTP)

Simply put, the RTP of a game is the amount that the game returns to the players over millions of spins. If a game has an RTP of 98%, this percentage lets you know that it will return $98 for every $100 that goes in. A lot of online casinos list the RTPs of their games. Pay attention to these. The better the RTP, the higher your chances of winning. It's as simple as that. To have an edge, stay away from slots that do not display their RTPs, or have RTPs lower than 96%.


In the casino world, volatility and variance have similar meanings. If the volatility is low, it means that chances of success are low, but when you win, it's a greater amount, and vice versa. On online casino slots, the volatility depends on the probability of the symbols lining up. The lower the probability, the higher the payouts.

Myths About Online Casino Slots

If you talk to folks about how casino slots function, there are bound to be a few myths that dominate the discussion. Here are some of those legends. It's crucial to know how truthful they are and not let them affect your decision-making when embarking on your casino experience.

Casinos do not rig their slot machines. They are entirely random and do not work in cycles. Other than that, it's essential to note that slots do not hold off on sizeable payouts until they recoup their losses. And finally, auto-playing your spins does not change the outcome whatsoever.

Have Fun

Casino slots hold hopes and dreams in a push of a button. Nothing comes close to the thrill of placing a bet and winning big. Knowing how online casinos work gives you an even better chance for glory. You won't go wrong if you choose an online casino that boasts certifications by parties you can trust, like eCOGRA, and play games with higher RTPs. If you are ever in doubt, has you covered.
