About Guessroo
Guessroo makes small daily guessing games you can play in a minute. Our first game is Yearline: each day you get 5 famous events and drag a marker to the year you think each one happened. Our second is Sizeroo: each day you guess how big 5 real things are, from a human hair to the distance to the Moon.
How scoring works
- Exact or 1 year off: 100 points.
- Every extra year off costs 2 points.
- 5 events a day, 500 points maximum.
A new set arrives at midnight in your local time. Your streak and scores are saved only in your own browser.
