How many questions are in this quiz?

This quiz has 103 questions about which two countries share a land border.

What is the quiz format?

Each question is multiple-choice with 4 options, and there is no timer.

Can I change the number of questions or difficulty?

Yes. Choose a shorter or longer question count and select a difficulty level before you start.

Do sea borders or “across the water” neighbors count?

No. The quiz focuses on countries that physically touch by land, not those separated by water.

Why do some questions feel much harder than others?

The quiz uses mixed difficulty, combining common borders with less-known pairs and tricky geographic exceptions.

About this quiz

What you’ll practice

Country-to-country adjacency across every region, from obvious neighbors to surprising border quirks. You’ll build faster recall of where nations sit relative to each other and which borders are land vs. “close but not touching.”

Each question uses 4 options and there’s no timer, so you can think through the map in your head before you answer. Adjust the question count for a quick run or a full 103-question challenge, and pick an easier or harder setting to match your confidence.

Common pitfalls to watch for

Many misses come from mixing up near neighbors (separated by a small sea, gulf, or lake) with true land borders. Another frequent trap is assuming borders exist because two countries appear close on a world map projection.

Confusing “across water” with a land border (straits, gulfs, lakes)
Forgetting tiny border segments and enclaves/exclaves
Mixing up similarly named countries or regions (e.g., Congo, Guinea)
Over-trusting distorted map projections and zoomed-out views
Missing one-country separators that break a would-be border

How the difficulty is balanced

Difficulty is mixed: you’ll see a blend of well-known bordering pairs and less familiar ones, so scores reflect both core geography and deeper map knowledge. If you want a smoother learning curve, start on an easier difficulty with fewer questions, then increase difficulty or length as your accuracy improves.
