Riverlink
Riverlink is a free daily geography game about rivers. Guess the mystery river in eight tries. After each guess, every column (continent, countries, how many countries, length, what it flows into and where it ends) shows whether you matched, were close, or were off.

How to play
Type a river and pick it from the list. The row that appears compares your guess with the mystery answer, one column at a time. Use the colors and arrows to rule things out, then guess again.
Questions
Where does the data come from?
From Wikidata (CC0): length, the countries a river runs through and what it flows into, for well-documented rivers. Continents come from Natural Earth (public domain).
What does 'Ends at' mean?
Whether the river flows into a sea or ocean, a lake, or another river.
Why do some rivers share countries?
Many rivers cross borders. Sharing at least one country with the answer shows as close.
How do I read the colors?
Purple means that column matches the answer. Striped yellow means close: a number within range, or related. Gray means no match. An arrow on a number points toward the answer: up if the answer is higher, down if it is lower.
How many guesses do I get?
Eight on most days. After four wrong guesses a hint shows the first letter of the answer, and after six it also shows the length.
What are the weekday twists?
Each day has its own rule. Monday is standard. Tuesday reveals one fact about the answer. Wednesday gives ten guesses. Thursday hides one column in your first three guesses. Friday turns the arrows off. Saturday gives only six guesses. Sunday is hard mode: every guess must be a possible answer given your clues.
When does a new puzzle appear?
At midnight in your time zone, and everyone sees the same answer on the same date.

Tips for Riverlink
- A very long river such as the Nile or Amazon shows you the length range at once.
- Rivers that share a country with the answer show as close, even when the continent differs.
- Tributaries share what they flow into, so a match there points to one river system.
