how close can you get?
№ 1Estimately is a free daily estimation puzzle. Each day everyone gets the same question about a real fact: how tall is a famous building, how far away is a planet, how many bones are in your hand? Your job is to guess the number. You don't need to know it exactly: any guess within 5% of the true answer counts.
You're told the unit and a range the answer is somewhere inside, such as "between 2,400 and 8,500 metres". Type a whole number on the pad and press Guess. If you're not close enough, you're told whether the answer is higher or lower and whether you were within 10%, within 25% or further off, and the range shrinks to match. There are 360 facts across topics like space, mountains, rivers, buildings, bridges, animals, the human body, science and sport, and they're shuffled so the same topic never comes up two days running. Every fact comes from a published reference that is shown when you finish, and every day is checked in advance so that steady halving of the range always gets there within six guesses.
You have six attempts. Solving it on your first attempt earns 12 points, then 10, 8, 6, 4 and 2 for attempts two to six. Each miss tells you how far away you were. Stuck early on? The helper shrinks the range to a much narrower window, but it halves the day's score and is only available during your first three attempts.
Your play streak counts the days in a row you've played, and your solved streak counts the days in a row you've solved the puzzle. Play seven days running and you earn a 7-point bonus, or 14 points if you solved all seven. Miss a day and the streaks start again. A new puzzle arrives every day at midnight UTC.
