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.
