Reborder is a quick geography puzzle about country borders. Each round gives you a border section to redraw, so you need to recognize the countries and judge the missing line from the map around it.
Look at the two countries, find where their border should begin and end, then draw the missing section. Use the mouse or touchscreen to make your line as close as possible to the real border.
Borders with several sharp turns are the most difficult. Small countries can also be tricky because there is less map area to use as a reference.
Don't start drawing immediately. First identify both countries and study the surrounding outline for a few seconds. This makes a surprisingly big difference on unfamiliar borders.
What caught me off guard was how different recognizing a country feels from drawing its actual border. I was more confident on simple coastlines, while curved inland borders required much more guessing. The short rounds also make mistakes easy to shrug off and try again.
