The hardest part of bonus buys isn't picking the slot, it's leaving the seat
Hit x340 on Wanted Dead or a Wild last night. Cashed out half immediately, kept playing with the rest. By 1am I'd given back €180 of it because I was "due another good one."
The math knows. The brain doesn't.
I've started setting a hard rule: any single hit over x100, I close the laptop for the night no matter how it's going.
Boring as hell but my monthly stats look way better since I started doing it three weeks ago.
The slot picks me a winning hand sometimes. The discipline is what I have to actually bring myself.
