I think you're onto something here, mate. I've noticed the same thing, where I get a hot streak with a new game, but then it seems like the house edge kicks in and I start losing more often. I think it's because our brains are wired to remember the wins and forget the losses, so we feel like we're on a roll when we switch to a new game. But like Saint-loup said, it's all about the expected value and the house edge. I've started keeping a journal of my wins and losses, and it's been eye-opening to see how the numbers really add up. Maybe we should start a thread on this and see if anyone else has had similar experiences?
