About fermi gg

How many plates of sushi do people eat at conveyor belt restaurants across Japan in a single day? You probably don't know the exact number, and that's the point of fermi gg. This free browser game gives you three numerical riddles each day, and you have to estimate a sensible answer without looking it up. Some questions sound ridiculous until you start breaking them into smaller pieces.

One Shot at Each Number

At midnight ET every day, three new questions appear. You only get one guess for each, so typing the first number that pops into your head can be risky. The questions might ask how many tennis rackets would cover a tennis court or how many marathons equal the length of the Great Wall of China.

You don't need to know everything beforehand. Start with a number you can estimate, then work outward. For a question about daily cookie consumption, for example, think about the population, how many people might eat cookies, and how many each person could have. The built-in calculator is there for these rough calculations, so you can check your arithmetic before submitting your answer.

Being Close Is What Counts

The scoring in fermi gg works a little differently from ordinary trivia. Instead of rewarding you for collecting points, it measures how far your estimate is from the actual answer as a multiplier. An exact guess scores 1×, while an answer that's ten times too high or too low scores 10×.

Your daily result is the average multiplier from all three questions. That means a lower number is better, and getting close matters more than producing a huge answer. Even if you miss the mark, the explanation after each question can show where your reasoning went off track.

A Little Math Goes a Long Way

Named after physicist Enrico Fermi, the game is built around making reasonable estimates when exact information isn't available. You won't always land on the right number, but a few sensible assumptions can get you closer than a wild guess. With just three questions per day, fermi gg gives you a quick mental workout that can leave you thinking about numbers in a different way.
