I have a feeling you are fooked from sign up. My thinking is certain registrations are signed up as losing players and say 1 in 10 a winning player. So no matter what you do you will never win. They might give you a percentage of your deposits back now and then just to keep you hooked. But the fact you are losing and re depositing that is what they want. People will say you are running cold but common sense will tell you it’s nothing to do with luck . They know your stake sizing, deposit amounts, re deposit frequency, games you play. RNG if it existed would eventually give you something good not cold or hot runs etc.
Casinos definitely control the games , not the provider. Some days you play all games are impossible to bonus. For sure playngo and pragmatic are definitely controlled by casinos.
