Hi to all our readers! Welcome to our article about variation in games of chances. As you surely know, casinos have always a long term advantage in all its games (baccarat, roulette, poker, blackjack and so on) . Otherwise, they will lose money at keeping those games, and we all know that is not the case.

The advantage of the casino is related to two main factors: the rules of the game and the variation, that is to say the payment the casino has to do to the winners. Statistics work in favor of the gambling sites and you can see that in the fact that there are more players losing than winning money.

However, it does not mean that you are unable to enter, play and end up with precious winning. The secret to do that has to do with luck and strategy. This combination can defeat the advantage of the casino, so it is very important for you to know about payment percentages and variation, so that you can make better decisions when it comes to play in the casino.

Return to Player

Also known as RTP, the return to player is the payout percentage of a game of chances in the long-term. In some way, it can be considered the opposite of the casino advantage. Therefore, RTP is the long-term statistics of the money won, divided by the total amount of money spent.

Consequently, with this number we are able to calculate the percentage related to the advantage of the casino. So that, if we consider, for example, 100% as the whole and the RTP is 6%, then the advantage of the house is 96%.The RTP depends on the type of game.

RTP Roulette

In the European roulette, the RTP is the same for all your bets. So,your chances of winning by betting on color is 18/37 (do not forget number zero) and the payout is 2 to 1. Thus, the percentage of the payment in the roulette is calculated according to this formula: 2* (18/37) = 0.973 = 9.73 . Then, the advantage of the house is 100% – 97.3% = 2.7%.

RTP Slots

Even though it depends on the game, the RTP in slot machines usually ranges between 92% and 97%. In this case, the percentage is determined by the symbols in every line (you can check them), the paytable and also the specific rules of the game that can makepossible the existence of some variation.

RTP Blackjack

As the blackjack rules can vary in different casinos (remember that you need to read them in the carpet), the RTP can also be different. In general, by using the basic strategy, the percentage is about 99.5% and, according to the continued use of cards, it can fluctuate between 95 and 102%.

Making use of this knowledge, some players wants to take advantage of that and put into practice the strategy of counting cards, in order to get an extra advantage that allows them to increase their winnings. However, this action is forbidden in the casinos and you can be banned if are surprised doing that.


Bear in mind that all this information we have provided for you is essential i order for you to make decisions and also to observe if you want to play in a casino with the purpose of getting winnings.

If you want to be a smart player, you need to know the difference between RTP of the game and the percentage of payment in the betting system.
