US 10 Circle Population Challenge

Directions

The object of this quiz is to place 10 circles of radius 100 miles on the map so that they contain the largest total population.

When you begin you’ll be given a 100-mile radius circle centered on the map. Move it using the mouse and click SUBMIT. You will be given a score for that circle corresponding to the total population among all US census tracts within it (there are about 85K total US census tracts averaging about 4K people each). Try to complete all 10 circles with the highest total score.

Any INTERSECTING areas are only counted one time, so no census tract will be counted more than once.

US 50K+ City Name Link Challenge

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.

US City Grid Blackout Largest City Challenge

Type 'easy' or 'hard' to begin the quiz. Easy is a 5-degree grid, hard is a 2.5-degree grid. Then, try to name the LARGEST city in each grid square which fits the category label for each square. To name a city, you must first click on the grid square to make it have a GREEN border. Then, type in the city answer for that square followed by a '.' (a period). You are given a score from 0 to 100 based on your answer's population compared to the largest city accepted in that square (100 being you named the largest city).

LETTER: means the city starts with that letter.
NUMBER RANGE: (such as 2-5, 10+) means the city contains that many letters (excluding spaces and special characters).
POPULATION RANGE: (such as 50-100K) means the city has that range for its population.
2+ WORDS means the city name has 2 or more words (words denoted by a space or hyphen).

AK and HI are NOT included in this quiz as they often have grid squares with only one answer for this quiz.

At the end of the quiz the largest population missed answer will show in each unanswered square, and for those answered the largest city will be listed if you didn't answer it.

US Circle Population Selection Challenge

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.
