About How Close?
How Close? is a free daily estimation game for people who like testing their sense of scale, distance, size, time, quantity, and surprising real-world numbers.
Each challenge gives you five estimation questions. Make a numeric guess, reveal the real answer, and earn points based on how close you were.
The idea
The game is deliberately quick: no account, no setup, and no need to already know the answer. The fun is in estimating.
Daily challenge
The goal is a short daily session with the same challenge available to everyone, plus a result that can be shared without revealing the answers.
Facts and sources
Published factual questions are intended to use trustworthy sources and a recorded verification date. The question library will grow as the game develops.
