The state selector controls which sportsbooks are shown in all of our tools. Choosing your state will filter sportsbooks so only those available are shown.
The state selector is in the top right of your screen:
It is behind the hamburger menu at the top right of the screen:
When you update the state selector, it will change the tools to only show sportsbooks available in that state. You can see sportsbook availability by state here.
In Settings → Sportsbooks State, you can choose your default state. This will make it so when you use any of the tools on the site, you will only see sportsbooks available in your state without having to choose from the dropdown.
