A Sudoku starts with some cells containing numbers (clues), and the goal is to solve the remaining cells. Proper Sudokus have one solution. [1] Players and investigators use a wide range of computer algorithms to solve Sudokus, study their properties, and make new puzzles, including Sudokus with interesting symmetries and other properties.
There are many Sudoku variants, partially characterized by size (N), and the shape of their regions. Unless noted, discussion in this article assumes classic Sudoku, i.e. N=9 (a 9×9 grid and 3×3 regions). A rectangular Sudoku uses rectangular regions of row-column dimension R×C.

In October 2020, a Kickstarter crowdfunding campaign was announced in order to produce a physical book with some of the channel's most popular puzzles.
Many Sudoku solving algorithms, such as brute force-backtracking and dancing links can solve most 9×9 puzzles efficiently, but combinatorial explosion occurs as n increases, creating practical limits to the properties of Sudokus that can be constructed, analyzed, and solved as n increases.

[4] [5] [7] In MAA Reviews (a publication of the Mathematical Association of America), reviewer Mark Hunacek called it called it "a delightful book which I thoroughly enjoyed reading" and said "a person with very limited background in mathematics, or a person without much experience solving Sudoku puzzles, could still find something of interest ...
