Online casino catalogs offer a wide range of games. It includes different types of slots, card and table entertainment, lotteries. But they are not released by casino owners, but by providers. They create game content from scratch and then test and certify it in independent laboratories. Only after that, the software is placed on the casino sites and becomes available for betting in free mode and for money.

Who is a provider and what is he responsible for

Providers are companies that develop games for online casinos. To do this, specialists from different fields are involved: designers, programmers, mathematicians, sound engineers, artists, testers, etc. Thanks to this, providers manage to create new titles and bring all their parameters to the quality and security standards that are in force in the iGaming industry. Released games immediately after certification are ready for integration into online casino platforms.

Provider responsibilities

When releasing slots, developers of gaming software think over their technical parameters. They are written in the characteristics of each title and cannot be changed. This means that casino owners cannot vary the return rates, volatility, and payout ratios at their own discretion. They are defined by the provider. In addition, he decides which bonus options, mechanics and bonus games will be supported in a particular slot. Software developers are also responsible for the reliability and safety of devices. To do this, they use different software algorithms and tools. In addition, it is on the providers' servers that the results of the spins are generated. Thus, the casino cannot influence the outcome of the rounds and deceive the players in any way.

Online Casino Responsibility

Online casino operators are responsible for the placement of gaming software on their websites and its smooth operation. They can independently set the range of rates and the denomination of coins, the supported currency. At their discretion, casino operators can issue free spins or bonuses to customers. But they are in no way tied to the level of return and other characteristics of slots, but act as separate incentives for players. They can be obtained at our Joker WIN casino.

How online casino gaming software works

Slot machines in online casinos are represented by software. It is based on different mathematical models. They are responsible for the level of variance, returns, payout ratios, the frequency of certain combinations. Based on this, the work of the random number generator is built. It is responsible for unpredictable results of the spins, but in accordance with the technical parameters of the model of each slot. Thus, players can be confident in the fairness of the spins and at the same time adjust their strategies taking into account the declared characteristics of the machines. The mechanics of the formation of prize combinations also depend on the underlying mathematical model. It can be linear, clustered, Megaways, All Wins, etc. As a result, users can receive payouts not only for consecutive symbols, but also lined up, horizontally, vertically, etc. This makes the gameplay more diverse and opens up opportunities for different strategies.
