1. The system is completely online, i.e. you do not need to install any software on your computers in the club, which increases the security of your club. 2. All the necessary software for the system is located on our servers outside the jurisdiction of countries where online gambling is prohibited. 3. Denomination for all games in the system. 4. There is a cumulative JackPot, can be broadcast on a separate screen. 5. In the system, you can disable not only the games you do not need, but also entire categories of games. 6. The system is built on the basis of the BetIN mathematics control system. Which is used in most modern electronic devices in the world. The BetIN mathematical system is based on taking into account the percentage of return not from the turnover, but from the player's bet, which allows you to fine-tune the logic of the game, and also allows you to manage events in the game such as bonuses, line wins, bonus wins, and winning amounts. 7. The system has more than 160 games from leading online gambling manufacturers. 8. The system works on any operating system including Android (Flash support is required) 9. The system can be configured and controlled from any device, anywhere where it is possible to connect to the Internet. 10. Changing parameters and managing the system occurs in real time, i.e. you do not need to disturb the player at the time of setting up the system and all changes will take effect instantly <...> PS The owner, "sitting at home", sets the percentage of greed, parameters for bonus games and calculates on the calculator how many suckers he got today.

Therefore, we repeatedly emphasize - 1) modern online gambling is a production machine for taking money, games are not just mathematics with a set % of turnover for a gambling house 2) a casino cannot only take, otherwise it will scare away all the players, so it is important to understand the current "settings" and make the most of the favorable period 3) play only where there are crowds of people, but remember that a lot of positive reviews on the network are distributed by the casinos themselves and their affiliates

How exactly the roulette puts out number after number, no one has written. Pneumatic is clear, there are two holes in each pocket. One sucks in air, and the other pushes it out. The ball will jump until the vacuum cleaner finds the number and will be blown out of the others.

Try to guess the sports score in football in the bookmaker's office, something like 5-2 with odds of 200. The chances will be higher.
Slots return zero. Absolutely everywhere. This year in general. And I even try to play where I have never played or very rarely. All the same. The day before yesterday I blew 50 bucks in party poker and another 20 bucks in red star. It got to the point that I played the minotaur in red star and in 20 minutes of the game I did not even see this monster. I already played 10 rubles, waited for this guy purely for the sake of interest and did not fall anywhere.
In the party in importal played and wolf. Half an hour bonus did not give in importal. In the end, when everything was eaten, on the last spins gave a bonus and x7 from the bet.
It's bad that it doesn't even let you swing. It immediately falls down and sometimes it throws it back up to the deposit and drains.
And also half the night like an idiot I played spins for 5 bucks. Where supposedly a million greens can fall.
In the end, this is what I decided. I won't play for two months. I'll save up some money. I'll go to Moscow. I'll buy myself some young black woman for the night, and such a wild one, who just flew in from some Nigerian tribe, and I'll have her like the last creature.
So, as they say, you need to remove all the negativity. Otherwise, there is nothing but frustration.

Negative expectation is built into all casino games. The optimal bet has nothing to do with it. MO is calculated as Alathissa described and is the same for any bets.
Adaptive game management is added on top and the real return is greatly reduced in favor of the casino. You can write % and jackpots whatever you want, but fall into the trap of cutting off large wins and say goodbye to your money.
If only the processing of transfers eats up 10% of the casino's deposits, then blackjack, roulette, sic bo, poker and the like are clearly unprofitable with fair play. And when the real return is 60-70%, then all the casinos are happy and there is enough for everything. And for rare large wins, you can arrange painful long verifications, in the hope that the player will not endure and will merge. In extreme cases, accuse the player of violating the rules (multi-accounting without evidence) and confiscate all the winnings.

How does this not depend on the optimal bet? If each bet has a different mathematical expectation over a distance of, say, 10 spins.
