Every landbased casino has an eye in the sky! Thinking a online provider such as evolution wouldent cover themself in some way would be fatal.
Here is my theory on how they do it: Your IP adress is uniq, when you change from one casino to another one, even if its not same company, evolution will know that its you playing. You can change username, but it want help.
Soo what then? Here is the role of the big eye, ever since you visited evolution game a profile has been created on you, in this profile everything is recorded, patterns, previouse successful sessions, previouse losses, repeatedly deposits ( when u chase losses) etc etc.
All this information they can use! how? well if you enter a table where you are up they can give themself an edge( decline bets, change ball,spinn harder/slower) remember a proff roulette spinner can make a ball land in a section. But But somebody won huge on that spin you say! well that somebody isent you, they will be dealt with later, today they deal with you 🙂
Thinfoil hat you say, i just have a theory of how its done, or how i would do it if i was in charge. Remember profiling your players isent illegal.
my best win in a row on roulette singel number is 4 in a row where i only bet on that excactly numbers, and man i promise you i saw some really crazy bounces on all of those balls( ball already landed firm in zero section to then suddently bounce to mid tier), but i dident mind since i won. week later they had it all back and some.
