About Micron: Measure by Eye
There is no ruler in this game. There is only your eye. Every day Micron draws seven figures and asks you for one point, one angle or one length on each. Find the centre of a lopsided blob. Bisect an angle. Aim exactly 47 degrees. Cut a bar at the golden ratio. Match an area you can only estimate. One attempt per task. No undo. Your miss is measured to the pixel and graded A, B, C or D, and the seven grades make your score out of 700. Everyone in the world gets the same seven tasks on the same day, so a score means something. The tasks get harder as the round goes on: the figures shrink and the tolerance tightens, so the same small slip costs more on task seven than it did on task one. TWO WAYS TO BE RANKED Global is opt-in and reciprocal. Show your score and you can see everyone else's; keep it private and the board stays shut. You can change your mind any day, and changing it never touches your score. Friends is a private group you open with a six-character code. It lists every member — including the ones who have not played yet — so you can see exactly who still owes you a round. A group holds fifty people. Competing with friends never requires publishing anything to the world. WHAT IS IN IT 49 kinds of task across three families: hit a point, aim a direction, match a size. Midpoints, ratios, circle and ellipse centres, balance points, perpendicular feet, reflections, angle bisections, trisections, tangents, equal areas, inscribed rings. Shapes are drawn fresh every day — polygons, stars, arcs, spirals and blobs that have never appeared before. Stuck? Watch a short video and Micron draws the tolerance ring around the answer for that task, so you can see how close you actually have to get. The day's seven tasks are built on your phone, so a weak signal never stops you playing. Only the leaderboard needs a connection. No account. No email. No sign-up. Pick a handle and play. Free, with ads. Ten languages. Two minutes a day.
