Why This Page Exists on a Site About Odds
Because everything else here is arithmetic, and arithmetic is not what decides how most sessions end. A player who knows the house edge exactly and raises their stake after four losses will still have an expensive evening, and a player who ignores every number on this site but keeps a flat stake and a round count will not.
The patterns above are the only genuinely predictive information available in this game, and they cost nothing to watch for.

The limits that prevent most of it are on the session limits page, and every guide is listed on the home page.
