First choose any Spain city by entering it and choosing it in the drop-down box. Then, name the largest Spain city in each 25km 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 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 ‘Madrid’ – you will be shown a circle of radius 25km centered at Madrid. Naming the largest city in this circle (Madridin this case) will cause another ‘ring’ of radius 25km to appear outside that circle. You now need to name the largest Spain 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 25-50km, it will expand to be a 25-75km ring, then 25-100km and so on until a qualifying city is found within the ring.
