The RTP is determined by developers through an average derived from a vast number of simulated spins, often totalling in the millions. Since it represents an average over an extended period, it might not accurately reflect the outcome of a short gaming session. Your actual winnings could be more, less, or you might not win anything at all. Also, it is always a good idea to play the game for free first, as this allows you to get a feel for how the game works before you risk any real cash. The games also use a Random Number Generator (RNG) to make them mathematically fair.
