How fast do you know the world?

Play a round

Pick a topic: Flags, Capitals, Shapes & places, Street clues, Rivers & seas, Culture, Facts or Mix. Above the topics you choose how many questions are on screen at once (1, 2 or 3), how long a round lasts, the difficulty, and where in the world the questions come from.

Tap the right answer. A right answer scores 10 points, with a bonus for answering fast, and the next question comes in at once. Answer several in a row to build a streak: 5 in a row doubles your points, 10 triples them and 15 gives four times. A wrong answer breaks the streak and shows the right answer for a moment. Pass swaps a question you don't know, with no points and no broken streak.

On a keyboard each row has its own keys: 1 2 3 4 for the top row, Q W E R for the middle and A S D F for the bottom, with 5, T and G to pass. Esc ends a round.

The daily challenge

Every day there are 30 new questions, the same for everyone. Each person gets one go per day: press Play and choose who's playing, so a family or a class can share one device. The card on the home screen and the result screen show how everyone on this device did today. Share sends your result as a grid of coloured squares.

Challenge a friend

After a round, Share makes a link with exactly the same questions. Your friend sees your score, plays the same round, and finds out who won.

Survival

No clock, three lives. The questions get harder the longer you last.

Study

Fix mistakes brings back the questions you missed or passed, a day later, then after a few days, until they stick.

Learn lists every fact the game asks about, topic by topic, each with its answer: to read, search and study. Tap a fact to star it, then practise your starred facts. A fact is collected once you have answered it right on three different days. Missed, at the top, gathers the facts you got wrong most recently.

Your world colours the map by what you know: green for mastered, yellow for learning, red for missed.
