Wyoming counties quiz

The 23 counties in the quiz

They’re the 23 counties of Wyoming, as counted by the US Census Bureau. The state capital, Cheyenne, is in Laramie County.

How to play

In Point mode we name a county and you tap it on the map; in Type mode one lights up and you type its name (accents don’t matter); and in Time trial you get 6 seconds per question. If you miss, we show you where it was, which way it lies and a hint drawn from the data: its size rank and its neighbors.

Each game has 10, 20 or all the questions, and at the end you can practice just the ones you missed. Your best score for each mode is saved in this browser only: neither we nor anyone else can see it, and there’s no sign-up.

The hardest ones

The smallest counties are the hardest, since they barely show on the map: Hot Springs (2,004 sq mi), Platte (2,081 sq mi), and Uinta (2,082 sq mi). Zoom in with the buttons or two fingers to tap them.

Tips to learn them

• Start with the three largest: Sweetwater, Fremont, and Carbon cover 28% of the area of Wyoming.
• The 6 counties bordering Montana trace that border on the map: Big Horn, Campbell, Crook, Park, Sheridan, and Teton.
• Laramie is the most populous (102,938 people in 2025) and, together with Natrona and Campbell, is home to 39% of Wyoming’s people.

Playing in class

If you teach in Wyoming, start with your school’s county and its neighbors and add a few each day. Otherwise, it’s a good way to get to know the state before studying it.
