Someone said to me many years ago that when you play slots in order to avoid losing and winning somewhat consistently you have to be very calm and have an extreme self control no matter what happens.
That's just BS lol, last week I lost more than $100 on Reactoonz. I was very calm, stayed in that game till my balance became zero.
100% BS indeed, the only way to avoid losing is not gambling

and they only way to win somewhat consistently is unlimited luck, nothing else. Self control is just to control our money management while gambling, it wont affect the result of our gambling session.
