You’ll be shown 25 different satellite images of country borders between two European countries. The border you are trying to identify will be highlighted in red. Name the two European countries which share this border. Occasionally a dependent territory will be involved, name the country not the territory. You can answer a border by typing the country names one after the other in any order, for example ‘francespain’ or ‘spainfrance.’

Borders may be disjointed, and in some cases where there are multiple separate border segments the full border may not be shown.
