Almost all online casinos operate on the same principle. They buy software from development companies and provide it to players. Please note that most online casinos offer the same slots and other games. This is because they use the same set of software, such as Microgaming, NetEntertainment, Play'n GO, etc.
There are online casinos that operate on their own software. However, there is always less trust in such operators, as there is a risk that they will “twist” the games in their favor. After all, they have such an opportunity. If the software is bought from specialized developers, then the online casino can no longer interfere with the system. Players will play online on the developer's server (this is what the vast majority of players do not understand), so you can be sure that the results are not rigged. Of course, if the developer is well-known, reliable and has a license.
At the heart of every game is a random number generator (RNG). It makes the game unpredictable. When you spin the reels of the slot machine, the RNG generates a random number combination, which is then converted into game symbols on your screen. A similar principle of operation operates in any other online casino games: cards, table games, lotteries.
Each game has its own RNG settings. They depend on the return to player percentage, known as RTP (return to player). It means how much, on average, players will receive in the form of winnings over a huge distance. A return percentage of 90% means that 90% of the money wagered by players will be returned to them in payouts, but only over a long distance.
Large distance means that we are talking about a huge number of bets. At a short distance, when it comes to several tens and hundreds of bets, the return percentage can be very different, be more or less ...
Often the return percentage is misunderstood. Players think that 90% should return during one game session. However, this is a percentage that is observed over a long period. For example, millions of slot machine spins. With a short game, the return percentage does not apply.
