The Rivers Quiz

Trace the great rivers. A pin anywhere along the water counts. This pack draws from 30 real places, and the quiz is not multiple choice: you get an unlabelled 3D globe, the name of a place, and 10 seconds to pin where it is. Points scale with how close you land and how fast you commit, so a near miss beats a wild stab and knowing beats guessing.

You are not pinning a city, you are pinning a line

This is the pack that breaks the city-pointing reflex. The answer is not a dot on the map but a thread of water, sometimes thousands of kilometres long, and a click anywhere along it measures zero kilometres. That sounds like a gift until you realise the scoring scales the points DOWN by the river's length: a hit on a compact European river pays nearly full marks, while the same zero-kilometre pin on the Nile, whose drawn geometry runs over 1,600 kilometres from the uplands to the delta, pays about half. The feature rule rewards you for knowing the river at all, then asks how big it is before it pays out.

The practical effect is that the famous rivers are not the easy ones. The Nile and the Amazon are huge, so a correct hit still costs you roughly half the distance points. The Danube, the Rhine, the Elbe are comparatively short, so landing on them is worth nearly the full payout. If you only know a river by name, aim for its mid-course where the channel is widest on the globe and your margin for error is largest; if you know its source and mouth, the centre of that span is the single safest pin.

Three habits that convert names into pins

Follow the relief, not the country. Rivers do not care about borders. The Danube crosses ten countries but the line itself runs from the Black Forest to the Black Sea, so the pin belongs on the arc that the highlands to the lowlands dictate. The same is true of the Volga, which drains the Russian plain north to the Caspian, and the Paraná, which gathers the southern continent's interior and pours it south. Trace the downhill path and you have traced the river.

Anchor on the sea the river feeds. Most players can place a sea more reliably than an inland course. The Niger loops through West Africa but it ends in the Gulf of Guinea, so knowing the gulf gives you the downstream end. The Indus drains to the Arabian Sea, the Murray to the Great Australian Bight, the São Francisco to the South Atlantic. Work inland from the ocean the river reaches, and the upstream half becomes far less of a guess.

Use the continental tilt. Rivers run downhill, and every continent tilts. Africa rises to the east and south, so its great rivers run outward from the interior: the Nile north, the Congo west, the Zambezi east. South America tilts west to east, so the Amazon, the Paraná and the Orinoco all find the Atlantic. Siberia tilts north, sending the Ob, the Yenisei and the Lena to the Arctic. The tilt tells you the direction before you have placed a single bend.

Where the pack quietly separates good from great

Because the geometry is a real line, not a single coordinate, two players who both "know" the river can score very differently. One pins the delta, the other pins the headwaters, and both measure zero kilometres, yet the player who recognised the river's SIZE, and so aimed where the line is densest on the globe, frames the answer more cheaply and keeps the map readable for the next question. The feature handicap is the whole game here: the pack is less "do you know the name" and more "do you know whether this is a compact channel or a continental vein".

For how the feature rule works in detail, including why a Sahara-sized target pays half and a small lake pays full, the feature rounds guide covers the scoring. For the broader skill of reading relief into position, Latitude Tells explains how climate and slope constrain where water even can flow.

How a run works

A run is 10 places sampled fresh from the pack each time, timed, and scored server-side onto the pack's own leaderboard. Your best run stands as your entry, and you can grind it down (or up) as long as you like. Free accounts get one ranked run a day; premium is unlimited.
