How review scores are calculated


We evaluate anonymous end-to-end crypto sportsbooks on a number of objective pre-defined criteria. We keep personal opinion to a minimum and use measurable and verifiable facts.

Here are the criteria we score sportsbooks on, a definition of 10/10 performance and examples of things that cause sportsbooks to lose points.

Min-bet and max-bet

For consistency we use the highest max-bet and the lowest min-bet we can find with odds close to even money.

User experience

User interface and user experience elements such as

  • Intuitive design.
  • Clear navigation.
  • Layout and clarity of things like betting history and account settings.
  • Site speed.

A 10/10 sportsbook has easy navigation, logical layout, intuitive settings, is easy to bet on and loads in under 3 seconds. We test all of this on desktop and mobile.

We use GTmetrix for site speed tests. The average speed of all crypto sportsbooks is 11.08 seconds and the fastest is Cloudbet (review, bettors are geo-blocked) at 8.1 seconds. This website loads in 3 seconds, thanks for asking!

Points are lost for things like intrusive casino adds, your preferences not being remembered, disorganized lists of markets, confusing bet slips and page load times over 5 seconds.

Nitrobetting has the best user experience with 8/10.


10/10 is given to whichever crypto sportsbook has the best odds. Other sportsbooks lose 1 point for every half % of overround they have above the sportsbook with the best odds.

For example, at the time of edit

Nitrogen (review) has the best odds of any sportsbook with a 3.64% overround.
Nitrogen receive 10/10.

Cloudbet has 4.17% overround (half a %  more than Nitrogen).
Cloudbet receive 9/10 (1 points less than Nitrogen).

Nitrobetting has the best odds with 8/10.

Range of bets

There are 2 elements in this rating

  1. The range of sports, leagues and events available to bet on.
  2. The range of different bet types and betting markets available per event.

A 10/10 sportsbook offers odds on everything from water polo to chess and horse racing. They offer dozens of different bet types from first player to score a 3 pointer in a basketball game to how many corners each team will take in the second half of a soccer game.

Points are lost by things like giving incorrect information, slow response time to emails, undertrained staff and only having 1 method of contact available.

Privacy, security and transparency

There are 2 main elements to this rating

  1. How much personal information do they require? The less the better.
  2. Is 2 factor authentication available?

A 10/10 sportsbook allows fully anonymous accounts without requiring an email address. Sportsbooks lose points

  • For every piece of information they require on signup.
  • If 2 factor authentication is not available.

Combines all of the above elements plus things like feedback we have received from real bettors, fun factor, trustworthiness, positive input to the crypto community and if a sportsbook’s bonuses are worth taking.
