Instructions
Step 1
Classic Sudoku is a square of 81 cells. This square, in turn, is divided into 3x3 squares, which consist of 9 numbers. According to the first basic rule, each row and each column of a large square cannot have the same numbers. According to the second rule, they should not be in each small square either.
Step 2
Start guessing with the number 1, then move in ascending order. Examine the entire playing field, find this number, evaluate its position in each of the rows, columns, small squares. For learning, use easy-level Sudoku, they have more initial numbers, so you will find the position of the missing unit right away.
Step 3
The answer will go faster if you use the search methods not individually, but collectively. For example, consider the three upper small squares at once. Suppose the first and second contain the number 1. Then evaluate in which lines it appears, for example, in the second and third. This means that in the third square, the unit will be in the top line. If two cells are already filled in this line, then feel free to put the number 1 in the remaining blank.
Step 4
Pass the other two series of small squares horizontally in the same way. Then repeat the process vertically, looking at the squares and the columns. Repeat the above steps for the remaining numbers from 2 to 9, then go back to number 1, and so on. Things will go faster because you have already filled in some of the cells. If a cell is controversial, leave it, then you will return to it.
Step 5
Define your strategy for the game, and soon you will learn to immediately grasp the field and instantly assess the situation. Difficulties usually arise at the very beginning, then the work argues and enthralls. Do not try to go straight to difficult Sudoku, first bring your skills to automatism at the beginner and intermediate levels.
