Horse betting sites with the best sign-up bonuses? — explained: You’ll have to shop around, because offers change all the time.

How to find these sites? You’ll have to shop around, because offers change all the time. And you’ll want to get used to reading the fine print. Check out these American online horse wagering sites to see what they have to offer.

Some general advice: Determine whether the site is legally licensed in your jurisdiction. You may want to sign up with an “offshore” site that offers a great sign-up bonus, but you need to know if you’ll have any legal recourse if there are problems.

Also, read the terms of the bonus carefully, as they are not all created equal. In most cases, you’ll have to wager at least the amount of your initial deposit within a specified period to collect the full bonus. But some sites require you to wager that amount to collect any of the bonus while other pay out incrementally as you reach milestones along the way.

Also, consider the site’s rewards program, which is usually more important than the sign-up bonus. In this case, look for the site that has the most-generous policy for your level of play. If you’re a small bettor, make sure the system is set up to reward you adequately, not just the “whales” who pump thousands of dollars through the system every day of the week.
