    User Experience: We are looking for sportsbook promos that make the betting process seamless. If we have a hunch on a game, we want the odds for that game at our fingertips. Easy-to-access Bet Slips, intuitive Parlay Features, and a detailed Betting History, are just a few of the user experience criteria our experts require from a top sports betting app.

  •

    Bonus Availability: We look for sportsbooks that offer real value in their customer deals. Not some snazzy marketing lingo, but real dollars available for you to collect. From killer welcome bonuses and promo codes with realistic conditions, to lucrative everyday customer offers, Bet Boosts, rebates, and VIP programs. Sportsbooks must offer something we can understand and can reasonably collect upon, or we won't recommend them to you.

    Payment Process: We all want to be able to fully realize our winnings and take our money home. Too many sportsbooks make it so difficult to withdraw your funds, that you are forced to bet again, seemingly indefinitely. At Odds Shark, we only recommend betting apps that our experts are comfortable holding their own bankroll. The best sportsbooks in the United States offer a variety of reliable deposit methods with reasonable payout speeds, so that you aren't  the friend that can't buy dinner because "all my money is in my betting account".

    Sport Odds Variety: We champion sites that provide extensive odds across a huge range of global sports. Sportsbooks must prove they are ready to promote big events properly. It isn't going to matter whether a betting site has Korean Baseball odds, if they can't get the Super Bowl right, but we know the way those popular betting markets are juiced. Every now and then, our Odds Shark handicappers have a gut-feeling on a European Handball match at 5am on a Wednesday. We want a sportsbook that lets us ride that out with them.

    Safety & Security: Odds Shark takes player safety very seriously. We only recommend betting sites that match our high degree of safety and security standards. That means a site must operate 256-bit SSL or TLS encryption as standard. They also need to provide fair, transparent Terms & Conditions for all players.
