About Spindex

Our system continuously collects real-time win and bet data from every casino we track. The data flows through a statistical analysis pipeline that uses Z-score analysis against rolling baselines to detect when slots are performing above or below their expected payout rates. For sports, we track public bets and rank bettors by an Edge Score (a composite of win rate × ROI × volume, with Bayesian shrinkage so 1-of-1 lucky wonders don't game the rankings).

Every slot in our database is tracked across multiple time windows — from the last hour to the past 7 days — giving you both short-term momentum and longer-term performance trends. We process roughly a million wins per day and maintain a rolling window of over 50 million tracked results.
