Sudoku with Additional Groups

Old Sudoku Variant

The first sudokus published in Dell Pencil Puzzles & Word Games (1979) were exemples of this sudoku variant. Here a puzzle created by me.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. Each of the numbers in circles below goes into one of the circle boxes in the diagram (not necessarily in the order given).

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. Each set of 4 small digits stands for the number in the four adjacent cells to this set.

Smash Sudoku

This is a combination of some sudoku variants.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. The grid must fulfill the following rules:

  • Sudoku X: The both main diagonals contain each the digits 1 through 9.
  • Sum Search Sudoku: The equal signs mark the relations between the sums of the digits of the cages. In cages there can't be the same digit repeated.
  • Arrow Sudoku: The digit in a circle is the sum of the digits which are marked with its arrow.
  • Ratio Sudoku: The fractions between two cells give the ratio of the digits. For example 2/3 can stand for the following combinations of numbers in the adjazent cells: 2 - 3, 4 - 6, 6 - 9, 3 - 2, 6 - 4 and 9 - 6.
  • Wheel Sudoku: The wheels in the grid contain each 4 values. These values will go in the cells the numbers are in. Doing this the wheels must be rotatated to the right position. (Not mirrored or changed the order of the digits.)

Wheel Skyscraper Sudoku

Fill the grid with the digits 1 to 9. The digits represent the height of the skyscraper in each cell. Each row, column and 3x3-box has exactly one of each digit. The clues along the edges tell you how many skyscrapers you can see from that vantage point. The wheels in the grid contain each 4 values. These values will go in the cells the numbers are in. Doing this the wheels must be rotatated to the right position. (Not mirrored or changed the order of the digits.)
