# UMG Gaming

> The unbiased US iGaming directory: player reviews and ratings for sweepstakes casinos, social casinos, sportsbooks, prediction markets and mystery box sites. No affiliate links, no operator money, no paid rankings. The full database is open data under CC BY-SA 4.0 (attribution required).

UMG Gaming currently tracks 331 active US iGaming sites with 19 published player reviews. A site's rating is the weighted average of its published player reviews: reviews from verified players (who proved a real account with the operator by forwarding an operator email) count five times, all others count once. Sites with no reviews are unrated. Ratings cannot be bought, and operators cannot pay to add, edit or remove reviews.
