Fill in the grid with the digits 1 to 9. Each row, column and 3x3-box will have exactly one of each digit. The clues along the egdes tell you in which cell you can find the maximum of the first three cells in the corresponding row or column.
Fill in the grid so that every row, every column, and every 3 x 3 box contains the digits 1 through 9. Numbers must be placed according to greater (>) and less (<) signs.

Fill the grid with the digits 1 to 9. Each row, column and 3x3-box has exactly one of each digit. The top of the pencil is one digit higher as the other digit of the pencil.
Fill in the grid so that every row, every column and every 3x3 box contains the digits 1 through 9. Numbers must be placed according to greater (>) and less (<) signs. The numbers between two cells give the difference of the digits.
Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. Some rows and columns have numbers. They represent the difference of the two ends.
Fill the grid with the digits 1 to 9. The digits represent the height of the skyscraper in each cell. Each row, column, 3x3-box and cells of the same color have exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point. There are no neighbouring cells with a difference of 3.
