Mapfold hides one country a day — the same one for everyone, changing at midnight UTC. Each round you're dealt three questions and you buy one. Every question is priced in bits: one bit halves the board of 192 countries exactly, so you can see what you're paying for before you spend it. Then you name a country. A miss costs a guess and folds everything the answer ruled out into night, and the globe turns to show you what's left. No instant loss, no account, no payment.
