How Virtual Gambling Machines Work: The Mechanics of Online Casino Games
Gambling in online casinos is fun until you start thinking about what exactly happens beyond the screen. While there is absolutely nothing wrong with online casinos per se, you should know how the machine works and what mechanics are behind each spin or hand in order to make yourself a more educated gambler. Let's take a look at how virtual gambling really works.
What Makes Up All Games Played Online: RNG
There is an algorithm that generates thousands of random numbers per second in the background of every virtual gambling game — from slots to card games and roulettes. As soon as you press the "Spin" button, the sequence of random numbers is chosen by the algorithm and interpreted into a result. The animation is merely a presentation of something that has already happened.
This means that it's impossible to talk about "hot" or "cold" machines because each spin is an entirely new sequence. There is absolutely no connection between the previous spin and the one that follows. The algorithm does not remember you or your gaming history and does not adjust its results according to your actions in any way whatsoever.
Legitimate online casinos submit their RNG code to testing labs, such as eCOGRA, iTech Labs, and GLI (Gaming Laboratories International) and undergo millions of simulated spins in order to prove the output randomness and reliability. The "Safe and Fair" seal, which you can find in a casino footer, links to the certificate of compliance with the industry standards of RNG. Check it out. If it leads you nowhere but to the website where you are looking at it from, beware of scams and frauds.
RTP and House Edge: The Flip Side of the Same Coin
The return to player (RTP) is a percentage of the total amount of money that players have gambled in the game that the machine will pay back over time. If your slot has an RTP of 96%, that means that after billions of spins, the machine returns you roughly $96 for each $100 wagered. That remaining 4% is the house edge. RTP alone does not show withdrawal rules or bonus restrictions, so CasinoGuiden can be used to compare licensed operators with clearly stated conditions.
A couple of important things to remember:
-
RTP is the long-run value. It is calculated on a huge scale; sometimes, it may be calculated based on billions of spins. Any particular session can be dramatically off the average value. For example, a 96% RTP game can return 200% of your wagered money in one session and 0% in another one.
-
The house edge depends on the game. Blackjack with optimal strategy has about 0.5% house edge; European roulette has 2.7%. Slots' house edge varies between 2 and 10%, depending on the title. Keno games often exceed 20% house edge. Your choice of a game matters way more than you think.
-
The volatility shows you how the house edge is distributed. In the case of low volatility, you will win quite frequently but not too much money. In the case of high volatility, you will win less frequently but with larger sums. Neither is better — both are suitable for different preferences and budget. High RTP with high volatility means that you may have to play quite a lot of spins before the RTP percentage affects your results.
Anomaly of Virtual Gambling: Live Dealer Games
Live games are streamed from special studios where live dealers play with cards and roulette wheels. There is no Random Number Generator involved here. You see everything in high definition video feed with optical character recognition (OCR) technology translating the results of the game into the interface of the machine. The house edge still remains but the source of the randomness is different.
The fact is important for gamblers who are not comfortable playing with the random algorithm and prefer to have some evidence of the honesty of the game. Live dealer games give you exactly that: you see every shuffle and every spin of the wheel in real-time mode.
Bonuses: What Do They Really Mean?
Online casinos are known for welcome bonuses, free spins and various deposit matches. Understanding their mechanics prevents any possible trouble later.
For example, if there is a 100% deposit match bonus up to $200 offered by the casino, that means that you get $200 in bonus credits for every $200 you deposit. The thing is, the bonus credits cannot be withdrawn immediately. First, you have to meet the required number of spins or plays — that is called the play-through requirement.
If the bonus mentioned above has a 30x play-through requirement, you will have to spend $6,000 in betting before the winnings from the bonus are released for withdrawal. Checking GuiaCasinos.mx helps distinguish licensed casinos with clearly stated bonus and withdrawal rules from sites that place important restrictions in the fine print. Otherwise, the bonus balance may expire or be lost through normal play.
What to Check Before Claiming a Bonus
Here are several things you should check before claiming any bonuses:
- Game contribution. Slots usually contribute 100% to the play-through requirements. In case of table games, such as blackjack, the contribution rate usually varies from 10% to 20% or 0% at all. If you prefer table games, you will have hard time using bonuses with high play-through requirements.
- Expiry period. The majority of bonuses expire within 7-30 days. If you have to make 40x play through requirement within 7 days and your deposit is modest, you have slim chances to complete it successfully.
- Maximum bet restriction. Betting above certain sum ($5-$10 per spin, in general) using bonus funds will make your bonus and winnings invalid.
The cleanest bonuses have low (under 20) or no play-through requirements with the direct cash-out of the winnings.
Payments and Withdrawals
The deposits in online casinos are usually fast. Withdrawals take much more time because of the KYC (Know Your Customer) verification procedures. That means submitting identity documents, proving your address and sometimes even the source of your funds. It is not some kind of extra trouble that you should avoid but a regulatory procedure protecting against the financial crime.
Withdrawal Times by Payment Method
Withdrawal time varies depending on the payment method.
- Usually, the fastest payments are made via electronic wallets: PayPal, Skrill and Neteller. They are usually processed within 24 hours.
- Bank transfers take from 3 to 5 working days.
- The withdrawal time in cryptocurrency is getting increasingly shorter and can take up to an hour.
Your first withdrawal from the casino will definitely take a longer time because of the required KYC verification. After that, the repeated withdrawal via the verified method will be faster than usual.
The Only Thing Every Gambler Should Know
House edge is permanent and mathematical. It is not a streak, bad luck or something adjustable according to your gambling history. All the games are constructed in a way that over time casino takes a portion of the total wagered amount of money. The particular session may indeed bring you profits — that's what keeps the players going. However, the game mechanics are created in a way that allows the casino to maintain its edge in the long term.
That does not mean that online gambling is not legitimate entertainment. It means that treating it as such with a predetermined budget, realistic expectations and without any belief that systems or any kind of patterns can somehow influence the house edge is the only reasonable approach.
Knowing the mechanics does not allow you to find an advantage that does not exist. It gives you an opportunity to make informed decisions and select the most suitable game with high RTP, check the bonus terms before claiming any of them, verify the casino and understand what happens in the game every time you play.
