FAQ
Do local and alternate names count?
Yes. Chang Jiang works for the Yangtze, Donau for the Danube, Ganga for the Ganges, and the Rio Grande answers to Río Bravo. 'River Thames' and 'Thames River' both score.
Do tributaries count?
Every river on the list counts, including famous tributaries like the Missouri, the Ohio, the Madeira, and the Blue Nile. If it has a name and a current, it's fair game.
What's the best strategy?
Think in watersheds. Start with the Amazon and its tributaries, then the Nile system, the Mississippi basin, then sweep Europe west to east, then southern and eastern Asia. Oceania and smaller famous rivers fill the gaps.
