I'm sorry you lost funds gambling. Maybe you're just too disappointed because of the free bonuses or spins you got that you didn't even experience winning at the game provider you entered. I'll be surprised when that happens.
If that's a high RTP percentage, I don't believe it because, in my mind, winning in gambling always depends on the luck of our game. No matter how good our mood is when gambling, if you are unlucky, you will definitely lose gambling.
I don't care for the funds lost as I have lost much more before, I am furious with the way it happened, the RTP is 96.xx% in that game and a bit less or more don't remember when you buy the bonus so 10 consecutive lost buy bonuses does not make a lot of sense. Anyway locking this thread now as I got enough insights and got the conclusion needed which is play only bonus money and never ever make a singe deposit there, as simple as that.
