The history of gambling goes back for thousands of years. People always have been asking themselves whether it is possible to win at gambling? The advantage of casinos is not significant and often hidden over the seemingly equal chances of win and loss. There are up-streaks (winning all the time), but is there any system to ensure winning at a casino? In this article, we would like to sort out this issue in detail and share with you the result and recommendations.

In land-based casinos, even if successful tactics is found, it is quickly become forbidden, for example, card counting in Blackjack. But in an online casino, there are legal ways to get the mathematical expectation of winning on your side, in addition to bonus hunting. With the growing numbers of online casinos, bonuses become more and more generous, and the terms have trapped inside. 

Is it possible to win in an online casino?

Getting a positive mathematical expectation of winning

Bonuses at trusted and white-labelled online casinos are usually coming with 35x or 40x wagering requirements. In the 1st case, you need to wager €3500 (for each €100 in the bonus money), in the 2nd case — €4000. Look for current deals in best casino bonuses offered.

Bonuses with 35х and 40х wagering

The secret is to find the bonus offers with a 40x wagering or lower then choose the slots with RTP of 97.14% or higher. In this case, a player will get a positive mathematical expectation of winning even in slots. That means a player will beat the casino in the long term. This data is based on our research and millions of spins on slots. 

According to the online casinos' rules, bonus money may be withdrawn as soon as the required number of bets (wagering) is played. On our website, we have an analysis of bonus promotions and slots. A player must read it, to know how to get a positive mathematical expectation. Find out more by clicking on the link:

For 35x wagering

40х wagering requirements

• To win at an online casino with an active bonus with 35x wagering, you need to play games that have RTP of more than 97.14%.
• To win at a casino with a bonus with 40x wagering, you need to play slots such as Blood Suckers (98%), Jackpot 6000 (98.86%) and Kings of Chicago (97.8%), because they pay out more than 97.5% of the bets placed and that is what we need.

Here is an example. If you play the slot Blood Suckers, which has a 98% RTP, with a bonus with 35x wagering, on average, you will win 0.86% of each €100 bet placed (100/3500 = 2.86% - 2% losing of RTP (which is 98%) = 0.86%). Statistically, for each stake of €1,000, you will win €8.6. In this case, you have a high chance of winning and it's higher than the average.

Myth or reality?

If you learn how to apply both strategies mentioned above at the same time, it will significantly increase your chances of winning at the online casino. By selecting the "News" tab in the central (top) menu of our site, you can get all information about bonuses, promotions, reload bonuses and events of online casinos. You will be able to prepare your schedule of deposits accordingly, so getting a bonus for each of them, and your chances of winning at the casino will increase significantly. Now let's turn it from mathematics to human psychology.

Basic principles

First, you need to know several fundamental principles of online casinos. Every player who wants to find a win-win online casino strategy needs to be familiar with the following terms and concepts:

• Dispersion of wins and losses (list of cycles of all slots).
• The advantage of the casino (read the article: why the casino always wins).

Dispersion (variance)

Dispersion (variance) is the spread of values associated with a game. For example, a player may one day hit a big win, but the next day may lose twice as much. Such situations occur if a player has selected games with high volatility. Even if a player is winning in the short term, with the increasing number of spins (hands, deals, etc.), the mathematical expectation will be closer to the exact statistical numbers (RTP). In the long term, players have no chances to be in plus (if the game is fair from both sides). From each dealt card and every reeled spin, the casino gets a percentage, so casinos in the long term always make the profit. Even if you are so good at following our recommendations and you are the master of winnings, the casino will take its money (as much as RTP is) from the other players. For example, casino wins 2.7% of the player's bets at the roulette, and 6% - at the poker. Casino's advantage has the opposite characteristics of mathematical expectation.

Testing the slot machines in free mode

Our recommendations in selecting a profitable casino slot are based on the same algorithms used in free mode and real money play.

The Netent software has so-called corrective variables, according to the slot, which would be either "positive," "neutral," or "negative." Since the random number generator is a critical component, these corrective variables increase or decrease the number of winnings by itself. These variables depend on player classification, the current balance of the slot and the prize pool.

That means if a slot is positive (hot), it will pay out more, but if it is negative (cold), all spins will be "unlucky." The trick is that the same corrective variables apply to online slots in free mode as well. It gives a massive advantage to the players, who, without risking their own money, can find slots in positive (hot) and then apply this knowledge and play for real money.

The strategy core

The strategy is to test the slots in free mode and select the most generous ones. Only after testing them in free mode, we recommend that you switch it to Play for real. After hitting some big winning, choose another slot and repeat the steps. Depending on how well you can determine the state of a slot, it will increase your advantage over casinos.

Minimum bets testing and "hit and run" strategy

There is information, that testing can be performed not in demo mode, but with minimum stakes in the chosen online casino. The results will correspond to the prize pool conception. It works like this: 

A player is opening an online slot and planning to play €10 stakes. Instead, he is launching it via minimum stake for 50 - 100 spins and looking for action and results of testing. If there is a lot of action (winnings, bonuses, free spins and bonus features) - the player switches it to planned €10 stake per spin. 

"Hit and Run" strategy means that you are moving from one slot to another after every big winning and never relaunch the same slots. This tactic fits medium and high stakes gambling.

The most profitable and unprofitable games

You may quickly find tables on the Internet which list the information about the casino advantage for games in different versions. From these tables, the benefit of the casino is somewhere between 0.1% and 30%. If the players can turn the expectation to their side, then players will get a real chance to win money in the long run. Know more about the most profitable slots by Netent:

Roulette and Blackjack

• Despite the common belief that there is a winning strategy while playing at roulette, you should know that such a strategy doesn't yet exist. The most popular roulette strategies are Whittaker and Martingale. Using these systems, you must sequence the lowering and raising of bets. This means you start with a small amount and doubling it up until you win then you should start from the beginning again. Yes, this leads to an increased dispersion. Still, you should know that the mathematical expectation (-2.7%), laid down in the rules of roulette. If you use this strategy, it will inevitably lead to a loss. By using this tactic, you can't win.

• Blackjack is one of the few games in which a player can get a mathematical advantage over the casino. At some live casinos, the dealer doesn't shuffle the decks by hands (dealer use shuffle machine). So players can't use the card counting technique, which can be quite useful. If you want to use the counting technique, so you can load a live blackjack table (shuffle by hands) observe the cards and try this technique without betting. You can start a game when the score is equal to +12 and above. Learn more about this by reading our articles on winning blackjack strategies. The essential thing playing Blackjack is to find a way to reduce the percentage of winning the casino. Some strategies reduce the casino to a minimum (0.5%). The basic strategy pattern is built on mathematical calculations. Do you want to learn more about the basic strategy of Blackjack.?
• When talking about the possibility of winning at casinos, we must not forget about the mathematical advantage. It is essential to know about the opportunities and dispersion of the exact game. Only then, players can win big at a casino.
