Bullseye

Bullseye is a browser game from A1 Games that launched on 8 November 2026 with puzzle #1. Each day brings a set of ten questions, the same for every player, and a new set unlocks at local midnight. Every answer is a number. Some are plain facts to recall or reason out, such as how many national flags use just two colours or how many Premier League goals a striker scored. Others ask for a year, and a few are Fermi estimates where you build the answer from rough parts, like how many biscuits would stack up to a basketball player's height.

You answer by dragging a target along a slider with a labelled range, or by tapping the plus and minus buttons to fine-tune. Two small tools sit above each question. One is a calculator whose result can be sent straight to the slider, and the other is a notepad for working. When you lock in, the game shows the real answer, how far off you were, the range that would have counted as a bullseye, and a link to the source behind the figure.

Scoring treats too high and too low alike. For counts it goes by how many times off you are, so guessing double or half scores the same, and a guess that is out by about ten percent still earns most of the points. Years are judged by distance within the slider's window. Ten questions make a total out of 1,000, and at the end you see how your score compares with other players that day, along with your streak and a row of squares to share.

Past days stay open in an archive calendar for practice, though they do not count toward the streak. There is no account, no download and no advertising on the page. It suits anyone who likes pub quiz numbers, back of the envelope sums, or games like Fermi and Best Guess, and a full set takes a few minutes.
