Rules

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!

Stereoscope viewer In 1838, his discovery of the stereoscopic viewer was described in a paper by Charles Wheatstone, On some remarkable, and hitherto unobserved, Phenomena of Binocular Vision, which he read to the Royal Society, London. This is the visual effect whereby pictures of an object drawn from slightly different viewpoints for individual eyes could be viewed with his stereoscope and give the perception of the object in three dimensions. He read a second part to this paper on 15 Jan 1852. This principle was later popularized with photographs to make stereo view cards.[Ref.: Philosophical Transactions of the Royal Society of London, Vol. 128, pp. 371-394 and Vol. 142, pp. 1-17.]
