How the border states quiz works

Most questions name a state and ask: Canada, Mexico or neither? Others ask which of four states borders Canada or Mexico, which Canadian province or territory touches a given state, which Mexican state does, and a few records (longest border, most provinces). Each state comes up at most once a round. Harder levels ask more about the 17 border states and fewer about the obvious inland ones.

The 13 states that border Canada

Ohio and Pennsylvania meet Ontario only in the middle of Lake Erie: a water boundary, but a real one, so they are counted. Michigan's border with Ontario runs mostly through the Great Lakes and the rivers between them. The Canada–United States border is 8,891 km (5,525 mi) long, the longest between any two countries, and Alaska holds 2,475 km (1,538 mi) of it.

The 4 states that border Mexico

State	Mexican states
California	Baja California
Arizona	Baja California and Sonora
New Mexico	Chihuahua and Sonora
Texas	Chihuahua, Coahuila, Nuevo León and Tamaulipas

The Mexico–United States border is about 3,145 km (1,954 mi). Texas has the longest stretch, about 2,019 km (1,254 mi), all of it along the Rio Grande.

The near-misses

Wisconsin reaches Lake Superior, but the international line in the lake runs past Minnesota and Michigan, not Wisconsin.
Oregon, Wyoming and South Dakota sit one state back from Canada.
Nevada, Utah and Colorado sit one state back from Mexico, and Oklahoma and Louisiana touch Texas, not Mexico.
Massachusetts, Connecticut and Rhode Island are the New England states without a Canadian border.
Montana borders three provinces (British Columbia, Alberta, Saskatchewan), more than any other state. Texas borders four Mexican states.
