Have you ever wondered if online slots actually pay out or if the system is rigged? You wouldn’t be the first, as many players will admit to questioning a slot’s legitimacy, especially after a losing run. You might wonder if the big wins even happen, as they have not come your way in a while.

However, online slots at regulated and licensed online casinos are indeed fair. It makes zero sense to risk their business and licensing by offering rigged slots to their players. They’d get a bad name and eventually go bust or shut down.

Slots operate on RNG (random number generators) and an RTP (return to player), which ensures a slot randomly pays out a certain amount of what it takes. In our guide, you’ll learn more about both of those, how payouts are determined, and why crypto casinos can offer even better payout rates.

By the end, you’ll have a clear understanding of slot fairness and how you can maximize your chances of winning.

Understanding Slot Payouts – How Online Slots Work

To clear up the myth that online slots are rigged, let us explain how they work and why you can have peace of mind that they’re fair and random.

RNG (Random Number Generator) – The Brain Behind Slots

Table games at a land-based casino or in a live dealer section online, like roulette, rely on luck and the laws of physics to determine wins. However, the developers of slot machines have had to create ‘luck’ and ‘randomness’ another way. They use random number generators, which are algorithms that ensure the results a slot provides are always random.

RNGs spin through hundreds of thousands of numbers, each representing a particular result on the reels.

But how do we know they’re not rigged? That’s a common yet understandable question. The answer is that as they’re regulated, online casinos must have their games tested for fairness.

That is carried out by RNG testing companies recognized by the regulatory authorities and the iGaming Industry. Top testing companies include:

eCOGRA
Gaming Laboratories International (GLI)
BMM Testlabs
iTech Labs

All the top software providers have earned certifications to prove their slot’s RNGs are fair and random.

Provably Fair Games in Crypto Casinos

Only found in crypto casino games, the Provably Fair algorithm takes RNG one step further. On regular slots at regular online casinos, you’re trusting the RNG is delivering fair results and the testing company that has certified it as fair. However, when playing a Provably Fair slot, you can verify the randomness of the results for yourself.

This is how it works:

When you start a casino game, the provably fair algorithm selects and encrypts a file on the blockchain ledger.
This file contains a sequence of random game results.
As you place bets, results are pulled in order from the encrypted file.
When you close your session, the file is decrypted and made public.
You can then verify the file using software to check that every bet was fair.
This ensures full transparency and confirms the integrity of your results.

The result is tamper-proof. It is accessible, but as an immutable record on the blockchain, it cannot be altered.

Different Types of Payouts in Online Slots

The way a slot can pay out will vary. All will offer traditional payouts when you land winning combinations on the reels. However, some may have or contribute to a progressive jackpot.

Fixed Payouts: All online slots will have a paytable that describes the symbol combinations needed to land specified rewards. For instance, you may need five matching Red Sevens along a payline to win a payout of 50x your stake. Slots can also use other reel mechanics like Pay Anywhere, Megaways, and Cluster Pays, but you’ll still receive rewards based on the different combinations created on the reels.

Progressive Jackpots: Progressive jackpot slots feature pooled jackpots independent of the regular spins you make. A small percentage of each spin bet, whether yours or anyone else’s, is added to the jackpots. They continue to grow until the RNG gods shine down on one player who literally ‘hits the jackpot’. The progressive jackpot resets to its original seed, and the process starts again.

What Is RTP, and How Does It Affect Payouts?

Return to Player (RTP) measures how much a casino game pays back over time. It also shows you the house edge for the casino.

For example, a slot with a 97% RTP means that, on average, it will pay out $97 of every $100 it has taken in wagers. The remaining 3% is the house edge, which is how online casinos guarantee they make money in the long run.

While RTP varies across games and casinos, regulated online casinos typically offer competitive rates. Since RTP is calculated over a large number of plays, it doesn’t guarantee individual wins.

That’s why it is widely accepted that players stand a better chance of winning on high RTP slots. Slots usually have RTPs of at least 95%, with the industry average at 96%. However, some can have 97% returns or more.

We have plenty of them here at mBitcasino, but if you want some recommendations, check out the following:
