Each spin is independent, so previous demo results do not determine what happens on the next spin. However, you should never use short demo session to try and get a gauge on hit frequency, bonus frequency, and RTP, as these are numbers and figures that are based on large mathematical samples. Where this rule applies, always check the RTP shown in the individual game’s information or paytable rather than assuming every version uses the provider’s highest published setting.
