There are two sudoku puzzles(1-6). Except grey cells, all remaining cells which are same positioned in both diagrams must contain different digits from each other. Also same positioned grey cells must contain same digits.
I suppose that, this is Classic Sudoku.
I have no idea, only know 6x6 (1-6) sudoku.
Classic Sudoku rules, 6x6 (1-6). Digits outside the grid show first digit in corresponding direction.
Classic Sudoku rules, 6x6(1-6), its form is half domino construction. And some segments have already filled in.
Every row, column and outlined regions contain exactly ones 1-7
Every row and column contain 1-N(for example 1-4). In the grid there are some empty cells(for the example every row and column has 2 empty cells). I suppose that dimension of the puzzle in competition will be 1-5, so grid will be dimension 7x7.
(16 points)/Digital Sudoku
Fill in the square with digits from 1 to 6 so that in each row, in each column, and in each 2x3 block all six digits are different. Digits are in digital form and some segments have already been filled in.

Fill the grid with the digits 1 to 6. The digits represent the height of the skyscraper in each cell. Each row, column and 2x3-box has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point.
Fill the grid with the digits 1 to 9. Each row, column and 2x3-box has exactly one of each digit.
Addition to Classic sudoku this variant has some circles. You can easily recognize its possible to get 1-9 Sudoku considering with circles. But circles must have another function that i havent understand yet. If you look at the example you will see, for instance from the left second column, top to bottom fifth cell in the same column. The cell contain a circle. And when you start to solve the example two numbers can be placed in the cell: 9-8. When you check answer of example circle has number 8. I didnt figure out why not 9?
Classic Sudoku rules, 1-8. There are four different symbol outside the grid. Each symbol represent some digit series and each symbol outside the grid show possibility of first two cells in the corresponding direction.
First symbol(seems like human
) mean: 5,6,7,8

Third symbol: odd number(1,3,5,7)
Last symbol: even number(2,4,6,8)
