The object of this quiz is to pick a 50K+ US city to start, then name successive 50K+ cities such that the next city's first letter is the last letter of the current city and the next city is as close to the current city as possible. You must name cities in the format 'City, State' with the state abbreviation following the city.

For example, you start with 'Chicago, IL' - you are now trying to name a city starting with 'O' (the last letter of 'Chicago') which is closest to Chicago. If you answer 'Omaha, NE' - now you are trying to name the closest city to Omaha which starts with a 'A' and so on.

The quiz ends at the 25th city from the starting one. You get 100 points for naming the closest city on each step, and they decline based on the distance your city was from the closest. You get 15 minutes to complete the quiz.

The object of this quiz is to click on the circle containing the largest population. When you begin you'll be shown 2 circles on the map with radii between 10 and 250 miles which do not intersect. Click on the one with the larger population within it (based on US census tract info) then 'Submit' - if you are correct you'll move on. One incorrect round and the quiz is over. Every 5 rounds the number of circles on the map will increase by 1. Try to build the longest streak of correct circles. Circles displayed will always be non-intersecting.

NOTE: You may have to zoom out to see all circles, occasionally a AK/HI circle will be included. Also, only population within the US is included in the total, any Canada/Mexico coverage counts as 0 population within the circle.
