Per Round Caps
Maximum stake per wallet per round keeps a single account from cornering the pool.
Pool Versus Pool
Winners split the losing pool pro rata. There is no house on the other side of your trade.
Leagues
Novice, Bronze, Silver, Gold, Diamond. You compete inside your band.
Methodology
For each round we take pooled stakes, subtract the 3% rake, and distribute the losing pool pro rata to winners. Net position is running total across all rounds for each wallet.
One Honest Paragraph
Fairness here is structural, not a promise of profit. Parimutuel payouts, per round caps, leagues, and a small public rake are the tools. Some players win. Many break even. Some lose. The board tells you the truth as it stands.
