PlainDaily Number Guessing Game: Name the Closest Answer
Plain sets seven targets a day, each a number such as a height, price, population or running time, and you name something in the category whose real value is as close as possible. Two rounds turn it around and ask for a straight numeric estimate, and one golden round counts double. It's free to play in your browser, with seven rounds a day and no account needed. There is no unlimited mode, but past puzzles can be replayed from the archive.

How to play Plain
- Read the category and the target number for the round.
- Within 30 seconds, type the thing you think is closest to that number; your first accepted answer locks in.
- Scoring is by ratio: within 1% is Dialed for a bonus, and twice or half as big scores the same.
- In the two estimate rounds, type a number directly; shorthand like 2.5k works.
Tips
- Think in ratios: being 10% off is the same whether the number is big or small.
- Answer reasonably fast, since your plane sinks while the clock runs.
- You do not know which round is golden until after, so treat every round seriously.
