Category Scoring Methodology

While most categories are scored using our default method of combining Yes / No points (Variable score) with a 1 - 10 Net Promoter Score (Opinion score), scoring does vary, as shown below.

  • Sports and Bets Offered - Yes/No with Opinion
  • Odds - Custom
  • Live Betting - Yes/No with Opinion
  • Mobile Betting - Yes/No with Opinion
  • Bonuses & Promotions - Opinion only
  • Education - Yes/No with Opinion
  • Ease of Use - Opinion only

Each individual category score is also translated into a star rating. Specifically:

  • 95% - 100% = 5 Stars
  • 85% - 94.99% = 4.5 Stars
  • 75% - 84.99% = 4 Stars
  • 65% - 74.99% = 3.5 Stars
  • 55% - 64.99% = 3 Stars
  • 45% - 54.99% = 2.5 Stars
  • 35% - 44.99% = 2 Stars
  • 25% - 34.99% = 1.5 Stars
  • 15% - 24.99% = 1 Stars
  • 5% - 14.99% = 0.5 Stars
  • 0% - 4.99% = 0 Stars

How We Score: Yes/No with Opinion

First, points are awarded for each “Yes” answer. The number of points awarded depends on the variable. Next, the total points earned from “Yes” answers is then divided by the total points possible to calculate a final Yes/No score.

To determine a final score for the category, this Yes/No score is then combined with an opinion score (1 – 10, with one being “very bad” and ten being “very good”). The weighting of the Yes/No score compared to the opinion score varies for each category. For example, 70% Yes/No, 30% Opinion.

Categories assessed in this manner include Sports and Bets Offered, Odds, Live Betting, Mobile Betting, Education, Bonuses and Promotions, and Ease of Use. Note, Odds do not incorporate an opinion score. Also, in assessing Ease of Use, sportsbooks are assessed on a 100% opinion weighted score.

How We Score: Custom

Scoring Odds requires separate custom formulas due to complexity.

Data from more than 1,700 bets (including moneyline, spread and total bets) was used to generate each sportsbook’s comparative odds ranking. Leagues and bet types collected include NCAA football moneyline bets, NCAA basketball moneyline bets, NFL moneyline, spread and total bets, NBA spread, moneyline and total bets, NHL moneyline, puckline and total bets, and soccer 3-way result (moneyline) bets. When collecting odds, we made sure to collect the same games at the same time for each sportsbook, ensuring data accuracy.
