New accounts are the casino's favorite. They want you hyped. So maybe, odds feel better at first. You win, you get hooked, you think it is your day. It is pure game design. The backend knows you are fresh, they want your loyalty, so they feed you a few wins. Old accounts? You are data now. You are less profitable. The machine dials it down. Your "luck" was the onboarding bait, not a cosmic blessing. Casinos ban multiple accounts because they know people figure this out fast. They want you to chase, but only if you play by their rules. If you feel your odds dropping after the first week or two, you are not crazy. That is just business, nothing personal. Anyone who has been around sees the pattern. The only thing random is how long it takes people to catch on.
