What is a retractable roof in sports betting?

The short answer

A stadium with a roof that can open or close. Weather depends on whether the roof is open or closed for the game.

Stadium weather is one reason a survivor team gets saved or spent. Plan those weeks in the Circa Survivor 2026 planner. It is unofficial and free to try. An account saves the build.

In plain English

Sometimes indoor, sometimes outdoor. Check if the roof is open!
