What are your thoughts on understanding roulette house edge differences? I've been doing some online research lately and noticed that different roulette variants have pretty distinct house edges. For example, American roulette seems to have a higher house edge than European or French versions. Does this really make a significant difference in the long run for your winnings, or is it more of a theoretical concern for casual players? I'm trying to decide which type of online roulette UK to focus on, and I'm wondering how much weight to give this factor.
