One thing is on screen with its number showing. Guess whether the next one is higher or lower. Keep a streak going as long as you can — or play the daily ten.
—
A higher-or-lower guessing game with a rotating set of real-world data — country populations, land area, film box office, the height of famous structures, animal weights and what big companies are worth. One item shows its number; you guess whether the next is above or below it.
They're approximate, rounded, real-world snapshots — populations and areas are stable, but figures like company market values and box-office totals move over time. They're accurate enough for a higher-or-lower guess, not a reference source.
Every run is generated from a seed. The challenge link carries that seed, so whoever opens it plays the identical sequence of comparisons in the same order. Nothing is uploaded — the seed is just a number in the URL.
