Africa 50 Km Expanding Circles Challenge – Choose City

First choose any Africa 50K+ city by entering it and choosing it in the drop-down box. Then, name the largest 50K+ Africa city in each 50km circle/ring as the rings expand outward from your city of choice. The first circle will include your city of choice as a possible answer if it is the largest 50K+ city in that area.

When you run out of time or end the quiz, you will see the current ring's correct answer at right (under 'Answer Stats' by your coordinates).

For example, if you choose 'Lagos, Nigeria' - you will be shown a circle of radius 50km centered at Lagos. Naming the largest city in this circle (Lagos in this case) will cause another 'ring' of radius 50km to appear outside that circle. You now need to name the largest 50K+ African city in that ring (but not within any previous circles/rings). If a city is not within the next ring of that distance, the ring will keep expanding by that distance until a city falls within it. So if a city doesn't fall within 50-100km, it will expand to be a 50-150km ring, then 50-200km and so on until a qualifying city is found within the ring.

Africa 50K+ City Name Link Challenge

The object of this quiz is to pick a 50K+ African city to start, then name successive 50K+ African 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. On this quiz alternates are generally accepted, however only the main (usually official) name is counted as it relates to naming the next city. Cities of the same name will answer the closest city first. NOTE: You must type a '.' (period) after the city to submit it. Cities must be a minimum of 50k population. The same city cannot be used twice in this quiz.

For example, you start with 'Cairo' - you are now trying to name a city starting with 'O' (the last letter of 'Cairo') which is closest to Cairo. If you answer 'Oran.' - now you are trying to name the closest city to Oran which starts with a 'N' 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.

Africa Bordering Country Challenge

Sorted from most bordering countries to fewest, then alphabetically. # of bordering countries shown.

Africa Capitals Triplets Blackout Challenge

Upon clicking START you will be presented with a 5×5 grid of 25 of the capital cities of African countries.

The object of this quiz is to choose the top 3 in the given category for the capitals shown in the grid. When you begin you’ll be given 25 different capitals plus a category to name the top 3 in, which will display just above the grid. For example, if the category says ‘Top 3 Largest Population’ you are to click on the 3 capitals with the largest population. If it says ‘Top 3 Lowest Population Density’ you are to click on the 3 whose population density is the lowest. You can deselect the first or second capital you chose on by re-clicking it, but when you choose the 3rd capital they will be submitted, removed from the grid, and you will get a score from 0-100 based on how close your set of 3 comes to the optimum set of 3 (which will be shown as a ‘Rank’ on top out of the # of possible sets of 3 for the last choice). When you’ve answered all 8 sets of 3 leaving only 1 capital the quiz is over. You get a 100 points bonus for completing the sets making for a total possible score of 2500.

Note: I set the Vatican's Cost Of Living to the same as Rome's, as there is no data for it.
