All the rules to regular sudoku apply as well as each number in each "cage" (the boxes with dotted lines) must be unique and add up to the number inside the cage.
Although Sudoku can be fun, it is not an activity that lends itself to "killer images". Try finding a friend interested in Sudoku and discussing interesting games.
Kakoru or kakuru is a cross between sudoku and crossnumbers puzzles. There's also "killer sudoku" which is just a larger grid size (12x12 or 16x16.)

There are several variations of Sudoku, including classic Sudoku, which features a 9x9 grid with numbers 1-9. Other types include Mini Sudoku, which typically has smaller grids like 4x4 or 6x6; Word Sudoku, where letters replace numbers; and X-Sudoku, where numbers must also lie on the diagonals of the grid. Additionally, there are variations like Killer Sudoku, which incorporates arithmetic constraints, and Jigsaw Sudoku, where the regions are irregular shapes rather than traditional boxes. Each variant offers unique challenges and gameplay experiences.

Yes the word how can be an adverb. For example, "How did you solve the sudoku puzzle? Other times it can be a conjunction: "He forgot how the switches had been set."
There are at least two sudoku variants that use inequalities. One is greater-than sudoku, in which there are traditionally no given numbers and less-than and greater-than symbols are placed between cells. Another more obscure variant is greater-than killer sudoku, in which inequalities are placed between groups of numbers, indicating that the sum of one group is greater than the sum of another. killersudokuonline.com is a great place to find both of these.
The Chinese Remainder Theorem (CRT) is not directly applicable for solving Sudoku puzzles. Sudoku relies on a grid-based logic system where numbers must be placed according to specific rules rather than modular arithmetic. However, some concepts from the CRT, like working with congruences, can theoretically inspire techniques for Sudoku solving, but they do not provide a direct solution method. Sudoku is typically solved using backtracking, constraint propagation, or other algorithmic approaches.
