How long can you go without a single wrong answer? Endless geography questions, no timer — one mistake and the run ends. Beat your personal best.
Streak Mode is endurance, not speed. There is no timer — just an unbroken chain of geography questions that continues until you get one wrong. Your best streak is saved and shown at the top of every run.
Questions never repeat within a run, so a long streak is real breadth — you can't coast on the same three flags. Difficulty stays constant; the pressure comes from the growing chain.
A no-time-limit run rewards careful recall over guessing. Because one miss ends the round, you learn to slow down on the countries you are unsure about — the opposite of the reflex Speed Mode trains.
