The classic version of Sudoku contains a 9*9 grid partially filled with numbers. To win the game you need to fill in the grid in the following way: enter numbers from 1 to 9 so that the numbers do not repeat in each row, column, and 3*3 area.

Even-odd sudoku is an extension of the classic game, where squares with odd numbers are circled.

Comparison sudoku is an extension of the classic game, where a greater-less sign appears between adjacent cells, which describes the relationship between the two numbers.

Dots sudoku is an extension of the classic game, where the game has black and white dots on the borders of the cells. If in neighboring cells one number is twice as large as the other, there is a black dot between them. If the numbers in neighboring cells differ by one, the dot between them is white. Between the numbers 1 and 2, the dot can be of any color.

Frame sudoku is an extension of the classic game where, in addition to the task, there are numbers around a grid. Each of the numbers represents the sum of the nearest three digits in a row or column.
