How do you calculate RTP? We determine the RTP of our games using a mix of mathematical analysis and game simulations. The results of this are used to establish the average return percentage that you see displayed on the games as the RTP. Our games are also verified by NMi, an independent specialist in game testing. We also make our results available to our external auditors and regulators as part of our commitment to game fairness. If you need any further assistance, please see our contact details here.
