The variance calculators are cited by Wikipedia, referenced by PokerNews, and credited by GTO Wizard. The rake comparison calculator draws from a public database of 1,546 rake rules across 19 networks.
Every poker room on this site is audited against the same checklist: rake structure at every stake, tournament schedules, bonus and rakeback terms, real player traffic, field softness, deposit and withdrawal options, and how each room’s variance profile affects your bankroll. When a room raises rake or guts a loyalty program, the review is updated.
PrimeDope is independently owned. Room rankings follow measured rake, traffic, and payout data rather than affiliate commissions, and critical reviews stay published.
