Which mountain is higher?
Choose whether the mountain on the right reaches a higher or lower elevation than the one on the left. Keep answering correctly to build your streak.
How to play
- Two mountains appear side by side (stacked on a phone). The first shows its summit elevation above sea level; the second keeps its value hidden.
- Decide whether the second one is higher or lower and press Higher or Lower.
- The hidden value counts up and your answer is judged. When you are right, the second card moves across and a new one takes its place.
- One wrong answer ends the run. There is no timer, and values stay fixed for the whole run. The two summits in a pair always differ by at least 20 m, and photographs are not to scale.
- Your result is saved in this browser. Once enough people have played a game, the results also show how your score ranks, and you can copy or share an image of your result, or replay.
Understanding the comparison
Compare elevation above sea level. A mountain rising from a high plateau can reach a higher summit than a dramatic peak near the coast. Photographs are not to scale.

Frequently asked questions
Is height measured from sea level?
Yes. The game compares each summit’s elevation above sea level, not its prominence or its height from base to summit.
How close can two mountains be?
At least 20 metres apart. Elevations are shown to the nearest metre.
Where do the elevations come from?
From national mapping, park and tourism agencies and UNESCO. Each mountain’s source and summit note appear in the game’s credits.
Which is the highest mountain in the game?
Mount Everest (Nepal / China), at 8,849 m.
Which is the lowest mountain in the game?
Mount Tsukuba (Japan), at 877 m.
How many mountains are in the game?
32. Two mountains are only paired when their heights differ by at least 20 metres.
Elevation, prominence and base-to-summit height
Elevation measures the summit relative to sea level. Prominence describes how far a summit rises above the saddle connecting it to higher terrain. Base-to-summit height depends on where you choose the base. These measures answer different questions.
The game uses elevation, so a peak on a high plateau can beat a mountain that looks more dramatic from a low valley. Source surveys and rounding can differ; the stated summit and measurement note identify what the game is comparing.
How this measure is defined
Elevations come from national mapping, park and tourism agencies and UNESCO. We use the named summit’s elevation above sea level, not prominence or height from the base. Values are displayed to the nearest metre; pairs differ by at least 20 m. Sources and summit notes are listed under How to play.

Summit elevation above sea level, not height from the base or prominence. Values are displayed to the nearest metre. Pairs differ by at least 20 m; photographs are not to scale.
The collection date tells you when we retrieved the source, not when every underlying observation was made. A failed refresh does not advance that date. For comparisons, the snapshot loaded for your run supplies the answers.
