Guess the NERDLE in 6 tries. After each try, the color of the tiles will change to show how close your guess is to the solution.

If the tile becomes GREEN, your number or operation is located at correct place. If the tile becomes RED, your number or opeartion exists within the expression, but at different place.

  • Each try is a calculation (math expression).
  • You can use 0 1 2 3 4 5 6 7 8 9 + - * / or =.
  • It must contain one “=”.
  • It must only have a number to the right of the “=”, not another calculation.
  • Standard order of operations applies, so calculate * and / before + and - eg. 3+2*5=13 not 25!

Example of the correct math expression:

Joke Of The Day

A pretty young college student...

A pretty young college student visited her professor's office after class. She glanced down the hall, closed his door and knelt down before him.
"I would do anything to pass this exam," she said. Leaning closer, she whispered seductively, "I mean, I would do anything."
He looked down at her and said, "You'll do anything?"
"Anything," she replied again.
His voice softened. "Anything," he repeated.
She smiled and again said, "Anything."
His voice turned to a whisper. "Would you...study?"

Heinrich Barkhausen

Born 2 Dec 1881; died 20 Feb 1956 at age 74.Heinrich Georg Barkhausen was a German physicist who discovered the Barkhausen effect (1919), a principle concerning changes in the magnetic properties of metal. His work in acoustics and magnetism led to the discovery that magnetization affects whole domains of a ferromagnetic material, rather than individual atoms alone. He discovered that a slow, smooth increase of a magnetic field applied to a piece of ferromagnetic material, such as iron, causes it to become magnetized, not continuously but in minute steps. With Karl Kurz, he developed the Barkhausen- Kurz oscillator (1920) for ultrahigh frequencies (forerunner of the microwave tube), leading to understanding of the principle of velocity modulation. He is also known for experiments on shortwave radio transmissions.
