How Chemle works

Open today’s case

Chemle Analytics
Operating manual

  1. 01

    A new case is loaded every day.

    Everyone gets the same unknown substance. It changes at 00:00 Vienna time.

  2. 02

    Pick Easy or Hard.

    Easy has everyday substances and approachable clues. Hard is a separate daily case for chemists, with expert clues. Each mode keeps its own streak.

  3. 03

    Name the substance.

    An element, a molecule, a material, a food, a medicine: anything with interesting chemistry.

  4. 04

    You have 6 ml of sample.

    Every analysis uses 1 ml, so watch the gauge on the display. Spelling and capitalisation don’t matter, and common synonyms count.

  5. 05

    Negative? The next clue appears.

    Clues start general and get more specific with every miss. The printout keeps all of them.

  6. 06

    Solve the case before the sample runs out.

    Keep your streak and share your result without spoiling the answer.

    > Wool: Negative · Material

  2. 02CHMMostly fructose and glucose

    > Honey: Match

Solved in 3/6, with 3 ml of sample to spare.

  • Match. You found today’s substance.

  • Class match. A known substance in the same class (e.g. both are elements).

  • Negative. A known substance from a different class.

  • No reference. A term we don’t recognise yet. It still uses 1 ml.

The class filter under the display keeps score for you: a lamp goes dark when its class is ruled out, and turns green once the class is confirmed.
