Gradus

Put everything in order, from planets to plants. For puzzlers and quizzers. Lock in your answer and share your result. Free, no ads, nothing tracked. Think. Rank. Repeat.

Six things. One correct order. One chance.

Every day, Gradus gives you a new set of six items to arrange along a single axis: earliest to latest, smallest to largest, slowest to fastest. Nudge them into order, lock in your answer, and find out how well you really know the world.

Your result is a grid of green and amber tiles with green for an exact spot, amber for off by one, plus a verdict on your calibration: The Oracle, Razor Sharp, Well Calibrated, Educated Guesser, Running on Vibes, or Confidently Scrambled. The grid never reveals the answer, so sharing it invites friends to play without spoiling anything.

Everyone plays the same puzzle on the same day. Your streak tracks how many consecutive days you have played.

Gradus is free, contains no advertisements, and stores nothing beyond your streak and today's result on your own device.
