The following rules take effect immediately:
Any player who breaks their streak can regain it by completing ten advanced calculus questions (available by email).
Prime numbers are considered lucky. Any guess containing a prime number will earn bonus points equal to the sum of the factors of that prime number (other than 1 and itself).
Real numbers continue to be available in all nerdle games but non-real numbers may be entered using the imaginary number keyboard.
Incorrect calculations may be accepted on the basis of artistic merit. For example, 1+2+3=4 may now be accepted because it is a nice calculation even though it does not add up.
Levels will be assigned to each player based on the quality of their guesses across all nerdle games. Levels are identified by the month created plus a letter for the year created (“F” for “First” meaning 2024) and a 3-digit level number. The first level identifier* should therefore be obvious.
First guesses used repeatedly without change are considered to be a lack of player creativity and may result in "could be more mathematically creative" being appended to your score when shared.
Order of operations mis-use will result in penalties: after attempting to enter a calculation where order of operations is applied incorrectly, players must recite "4+8/4*2 does not equal 5 or 6" ten times.
Odd numbers will be restricted in all future nerdles: an odd number may only appear in a solution if the multiple of its prime factors is also odd.
Lastly, all numbots will now be uniquely identified to aid tracking. Tracking numbers consist of two/three letters to identify the character name and two digits to represent their artistic representation. Examples below:
* Level 1 is therefore "April-F-001"
