Since RTP configurations can vary by casino, market and jurisdiction, we strongly recommend checking the in-game info screen at your chosen operator before you spend any real money. As such, a high RTP slot isn’t an automatic guarantee of your returns in the short-term. Slots are games of chance, powered by RNGs (Random Number Generators).

Let’s say, for instance, that a slot machine has a 90% RTP.
