Fun Facts: 2021
(Published on 26. January 2021, 00:06 by EliasKar)
1) Normal Sudoku rules apply.
2) Anti-knight constraint.
3) Little Killer clues show the sum of the digits along the indicated diagonal, which may contain repeats.
4) The two cells separated by a blue dot have a difference of 3 or 6.
The little killer clues in this puzzle were inspired by the number 2021:
-43 and 47 are the only two non-trivial factors of 2021.
-55 is the concatenation of the digital root of 2021 with itself.
-11 is the number of digits that are necessary to represent 2021 in the binary system.
-22 is the next number in the sequence 20,21,...
-34 is the number that would be displayed on the score board of a soccer match, if a goal was scored exactly 2021 seconds after the beginning.
