How to Play Higher or Lower
Each card shows a fact with a number: a country's area, a mountain's height, a movie's release year and more. Decide if the next card's number is higher or lower. The Daily is 10 guesses, the same for everyone today. Endless mode keeps going until you miss.
Rules in 3 steps
- Read the left card. It shows a thing and its number, for example a mountain and its height in meters.
- Guess the right card. Is the right card's number higher or lower than the left one? Tap Higher or Lower.
- Keep going. The right card moves to the left and a new card appears. In the Daily you get 10 guesses; in Endless one miss ends your run.
Scoring
- Daily: one point per correct guess, out of 10. A miss does not end the Daily; you play all 10.
- Endless: your score is your streak. One wrong guess ends the run. Your best streak is saved in your browser.
- The two numbers on screen are never equal, and close pairs are skipped when sources disagree (for example, river lengths).
Topics
- Country area. Total area in square kilometers, rounded. Figures differ slightly between sources.
- Mountain heights. Summit height in meters above sea level.
- Famous structures. Height in meters as commonly quoted. Where it matters, the label says what is measured.
- Solar system sizes. Mean diameter in kilometers.
- Atomic numbers. The number of protons in one atom of the element.
- Movie release years. Year of first U.S. theatrical release.
- River lengths. Approximate length in kilometers. River lengths vary a lot between sources, so close pairs are never shown.
Tips
- Use anchors. If you know Mount Everest is 8,849 m, you can place most mountains against it.
- Think in orders of magnitude for areas and diameters: is it ten times bigger, or just a bit bigger?
- For movies, recall a nearby event: a sequel, an actor's age, the tech in the film.
- In Endless, pick one topic you know well to build a long streak, then try All topics.
FAQ
Is Higher or Lower free?
Yes. The Daily and Endless modes are free with no sign-up.
When does the Daily change?
A new Daily 10 starts at midnight US Eastern Time. Everyone gets the same 10 guesses that day.
Where do the numbers come from?
Our team wrote the data set from standard reference figures (areas, heights, release years and so on). Values are rounded, and some figures differ slightly between sources, so we never show two numbers that are too close to call. If you spot an error, email us.
Can I pick a topic?
Yes. In Endless mode you can play All topics or choose one: country areas, mountains, structures, solar system sizes, atomic numbers, movie years or rivers.
