It occurred to me because when I signed up at a new casino, the odds of winning were quite high. I didn't know if it was just coincidence or if it was designed to win. After using the same account for a while, the win rate decreased. I excluded sports betting.
This is the first time I’ve read this theory. I have not experienced this because I only have one account on each gambling casino I play. What difference does it make if the house always wins? How many times have you checked your bets on each account?
It may be a coincidence unless we fully establish this, then we will see gamblers creating another account just to beat the house.
All I know is there is no strategy to beat the house consistently, and this method even if its effective will not work because you will be accused of multi accounting.
