Utah counties quiz

The 29 counties in the quiz

They’re the 29 counties of Utah, as counted by the US Census Bureau. The state capital, Salt Lake City, is in Salt Lake 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: Davis (325 sq mi), Morgan (609 sq mi), and Weber (611 sq mi). Zoom in with the buttons or two fingers to tap them.

Tips to learn them

• Start with the three largest: San Juan, Tooele, and Millard cover 26% of the area of Utah.
• The 7 counties bordering Nevada trace that border on the map: Beaver, Box Elder, Iron, Juab, Millard, Tooele, and Washington.
• Utah has the most neighbors: it borders 7 counties. Once you place it, you have a landmark for many more.
• Salt Lake is the most populous (1,220,916 people in 2025) and, together with Utah and Davis, is home to 67% of Utah’s people.

Playing in class

If you teach in Utah, 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.

With the Challenge your class link, everyone gets the same questions in the same order, with no accounts or passwords, and each student sees their own score, time and streak. To practice on paper, there’s a printable worksheet of the same map with an answer key.
