RTP (Return to Player) is one of the main parameters of the game slot. This indicator determines the percentage of funds that the slot machine returns to long distance players.
For example, an RTP of 96% means that out of every 100 betting units, the game returns an average of 96 units to players. The remaining 4% forms the margin of the platform operator.
RTP is calculated based on the mathematical model of the game and depends on the structure of the reels, the probability of symbols and the paytable. This indicator is an important element of the balance of the slot game.
Slot machine developers carefully calculate RTP to ensure interesting gameplay and compliance with the requirements of gaming platforms.
JackCode develops mathematical models of slot games and performs RTP calculations taking into account game mechanics and industry requirements.
