Any winnings in such games are always pure mathematics and luck, so looking for some system or pattern here makes no sense at all. Today you have a maximum, and tomorrow you can drain the entire balance in a matter of minutes and not even notice how it happened. In general, I believe that this should be treated exclusively as paid entertainment: you went in, spent a certain amount that is absolutely not a pity to lose, got your dose of adrenaline and went to do other things. If you perceive this as a source of income or expect constant gifts from fate, then this is a direct path to disappointment. It is best to play soberly, set strict limits for the day and never try to win back if the session did not work out from the very beginning. Everyone spins slots at their own peril and risk, and other people's stories about their successes do not guarantee that you will have the same.
