Odd One Out: Geography

Every round shows four options — three that belong to a category and one impostor. The question tells you the category ("Which of these is NOT a country in Europe?"), and your job is a single tap: pick the one that doesn't fit. Keep picking correctly and the rounds keep coming; you carry three lives, and a miss costs one of them, so the score to chase is how many rounds you get right before the third heart goes.

The traps are the point. Guyana sits next to Ghana and Guinea in your memory but lies an ocean away; Sydney and Istanbul feel like capitals and aren't. Each round ends with a one-line explanation of why the odd one is odd, so a miss always teaches you the fact you were missing.

How to play

• Read the question. Then tap the option that does not belong.
• You get one pick for each round. There are no second guesses.
• The quiz marks your answer immediately. It also gives one line that explains the answer.
• You start with three lives. The hearts in the top bar show the lives that you have.
• A correct answer gives one point. A wrong answer costs one life.
• A round that costs a life gives no points. The quiz continues with the next round.
• The run ends when you lose the third life. It also ends when you play all the rounds.
• Select "Review rounds" on the result screen to see each round that you played.

What counts in this quiz

• The quiz holds 100 geography categories — continents, capitals, landlocked countries, island nations, borders and more. One run can use all of them, in a new order every time.
• Every option is checked against the category as commonly defined: UN-member countries, official national capitals, the five Nordic states, and so on.
• Your score is the number of correct answers. The maximum score is 100 — every round in the quiz.
• A wrong answer costs one life. You keep the points that you have.
• The timer counts up from your first pick. It only separates equal scores on the leaderboard.

What's not included — and why

• No trick overlaps — an impostor is never arguably inside the category (you won't be asked to call Kazakhstan "not European" or Denmark "not an island nation"; borderline cases are simply not used).
• No repeat of the same category twice in one run — each round tests a different set.

Good to know

• Guyana is the only English-speaking country in South America — one reason it so often gets mentally filed next to African namesakes like Ghana and Guinea.
• Rio de Janeiro was Brazil's capital for nearly 200 years before Brasília — a city built from scratch — took over in 1960.
• Bolivia still maintains a navy, over 140 years after losing its coastline to Chile in the War of the Pacific.
