About game
Sudoku Box is one of the most popular puzzle games of all time. The goal of Sudoku is to fill a 9x9 grid with numbers, in which each row, column, and 3x3 section contains all the numbers from 1 to 9.
How to play
Use numbers from 1 to 9
Sudoku is played on a 9 x 9 grid, with 81 grids in total. Within the grid are 9 "squares" (3 x 3 grids). Each horizontal row, vertical column, and square (9 grids each) must be filled with the numbers 1-9, without repeating any numbers in the row, column, or square.
No guessing
If you don't know what number to put in a certain grid, keep scanning other areas of the grid until you see an opportunity to put the right number in. But don't try to "force" anything - Sudoku rewards patience, understanding, and solving different combinations, not blind luck or guessing.
Use the method of elimination
One way to figure out what numbers can go into each square is to use the "method of elimination" by checking what other numbers are already in each square, since you can't duplicate the numbers 1-9 in each square, row, or column.
