My gambling money is limited anyway, if only I had read this earlier, I probably would have prioritized this somehow, since I often play slot games too because this is really where I started - with slot games really.
But it looks like I don't fit their criteria either since I'm not a regular slot player at their casino, because I play at different casinos whenever I have money to gamble at crypto casinos.
Even you are rich and have a lot of money, you must limit your money for gambling. It is a very first important step for your responsible gambling by controlling your gambling capital at a limit that is acceptable and safe for your overal finance. You don't have to be the poor to avoid using all money for gambling, as identify a threshold of your gambling capital which should be very small in comparison with your general finance, is vital for your financial status.
You can win or lose money with gambling but gambling itself is risky, easy to lose money so with good risk management, you will not use all money for gambling. From that capital for gambling, you can split it to which part is used for slot games and it can be small or big in your total gambling capital. It's all well as you are afford to lose your money with bets, so which games you are ready to play is not too important.
