Flux RTP, volatility and max win
RTP: the default return to player is 96.20%, meaning that over a very large number of spins the game is designed to pay back around 96.2 units for every 100 wagered. Some casinos may run a lower configuration; the info screen inside the game shows the exact figure. How RTP works.
Volatility: The provider hasn't published an official volatility rating for Flux, so we don't label it. Judge it from the demo: if wins are rare but bonus rounds carry most of the value, treat it as a higher-variance game and size your stake accordingly. Volatility explained.
Max win: the maximum payout is 2,562x the stake. What max win really means.
