Listen, I get why this is confusing, it’s not just you. Most of the time it’s RNG plus house edge doing its thing, but the way bonuses and wagering rules are structured can totally change how long your balance survives. Some sites just feel brutal because terms are hidden in fine print. If you’re trying to compare platforms, transparency matters a lot, and reviews can help spot which ones explain RTP and rules clearly, for example checking resources like Finestonlinegambling.com since it collects a bunch of comparisons and user feedback, then you just have to dig through it and not trust hype blindly. Anyway, hope that helps a bit, gambling stuff is messy.
