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!

Roller Coaster In 1898, the loop-de-loop Roller Coaster having a section of vertical circular spiral track was patented by Edwin Prescott (U.S. No. 609164). He described how “due to centrifugal action, the contents of the car remains securely in place and the car follows the track.” The axles of the car’s wheels had the essential ability to pivot slightly on the car frame in both horizontal and vertical directions to closely follow the horizontal and vertical curves of the track. For safety, he provided additional wheels on the opposite side of the main rail with their own safety track to prevent the car from leaving the main track, even if the car was inverted while travelling with insufficient centrifugal force. An elevator chain moved the car from a passenger-station on the ground, up to a much higher section of track as the starting point.«
