This app contains 100 puzzles. It asks the operator to decide which country -among two- has the larger population.
As the operator navigates through 100 puzzles, each puzzle offers two options.
A click will select a choice, also will show the correct answer, along the populations of the two countries, and the difference in population.
The app navigates all countries of the world and compares countries of similar population, relatively.
Music is played in the background to add to your enjoyment.
