Not selected

Your spending limit is €100.00. You could lose this entire amount before completing the selected spins (about 100 losing-stake spins). Total wagering turnover is not the same as the cash required, because winnings can be replayed.

High RTP does not cancel high volatility — long losing streaks are normal on high-variance games. Confirm the live RTP and rules in the casino game help file; catalog values are the highest published tier.

How to read the numbers

House hold is 100% minus RTP. Theoretical expected loss is turnover × hold. That average assumes a huge number of spins — your next session can be far better or worse, especially on high-volatility games.

Pair this with the RTP calculator for stake × rounds alone, or the wagering calculator when clearing a bonus. Browse all Slot Intelligence tools on the hub.

Frequently asked questions

What is a slot session explorer?
Direct answer: It combines stake, planned spins, RTP and an optional spending limit to show theoretical turnover and expected loss — plus whether your cash limit can be exhausted before you finish the planned spins. It is educational maths, not a forecast.
Why does turnover exceed my spending limit?
Direct answer: Turnover is stake × spins. Wins can be replayed, so total wagered can far exceed the cash you brought. Your spending limit is the cash you are willing to lose — not the same number as turnover.
Does volatility change the expected loss formula?
Direct answer: Expected loss from RTP is a long-run average. Volatility changes how bumpy the path is — high volatility means larger swings and a higher chance of hitting your spending limit early, even at the same RTP.
