Fill in the grid so that every row, every column, and every marked region contains the digits 1 through 9. The grid is joined at the outermost columns as if it were a cylindrical grid.

Fill in the grid so that every row, every column, and every marked region contains the digits 1 through 9. The grid is joined at the outermost columns and rows as if it were a toroidal grid.

Fill in the grid so that every row, every column, and cells with the same color contain the digits 1 through 9. (There aren't any boxes.)

Fill in the grid so that every row, every column, and cells with the same color contain the digits 1 through 9. (There aren't any boxes.)

Divide the grid into areas and write a number in every field. The numbers in the same area have to be the same and have to tell the number of fields in that area. Areas of same size my not touch horizontally or vertically, but diagonally. Given numbers may belong to the same area, and it's possible that there are areas, where no number is given, even with larger numbers as the once shown. In golden cells the number is the sum of the gaps of this cell with its orthogonal adjazent neighbors. In white cells the number can not be the sum of the gaps of this cell with its orthogonal adjazent neighbors.

Fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 through 9. The colored extra-regions must contain each the digits 1 through 9.

Fill in the grid so that every row, every column, every 3x3 box and the cyan cells contain the digits 1 through 9.
