How the questions are made
Every round is generated fresh from our data: fifteen questions, one per sector, with sectors 1 to 5 easy, 6 to 10 medium and 11 to 15 hard. A challenge link replays exactly the same fifteen questions.
State capitals and postal abbreviations are the official ones; land borders follow our Border Blitz rules (corners and water boundaries do not count); regions are the four US Census Bureau regions. Size questions use the ten largest and ten smallest states by total area (Census TIGERweb) and the ten most populous (Census Vintage 2025): they either compare states from one of those lists or set one of them against states outside it, so the answer is always certain.
States fall into three familiarity bands: the ten most populous plus Alaska and Hawaii (easy sectors), sixteen small, seldom-mentioned states such as Vermont, the Dakotas and Wyoming (hard sectors), and the rest (medium). In abbreviation questions the options share more first letters the deeper you go, and in the hard size questions the figures are close.
Capitals that contain the state's name (Indianapolis, Oklahoma City) are not asked, and states whose Census region often surprises people (such as Delaware, Maryland, Texas, Missouri, the Dakotas, Alaska and Hawaii) get no region questions.
