Fill the grid with the digits 1 through 9. Each row, column and 3x3-box has exactly one of each digit. The coloured points tell you whether the sum in the marked cage is odd (yellow point) or even (green point). In cages there can't be the same digit repeated.

Fill in the grid so that every row, every column and the 3x3 boxes contain the numbers 1 through 9. The sum of the numbers within each sub-region is equal to the specified number. No numbers can be repeated in any cage.

Fill cages in the grid so that each cell is part of exactly one cage. Additional fill digits in the grid so that every row, every column, and every 3 x 3 box contains the digits 1 through 9. In the upper left cell of every cage is exactly one number and this is the sum of the digits in this cage. In cages no number is repeated.

One cage border is given.

Fill cages in the grid so that each cell is part of exactly one cage. Additional fill digits in the grid so that every row, every column, and every 3 x 3 box contains the digits 1 through 9. In every cage is exactly one number and this is the sum of the digits in this cage. All cages have two or three cells. In cages no number is repeated.

Locate the position of a 10-ship fleet in the left grid. The shapes of the ships are shown at the bottom of the left grid. There is one 4x1 battleship, two 3x1 cruisers, three 2x1 destroyers and 4 1x1 submarines. The numbers around the left grid indicate the number of cells occupied by ships in each row or column. Ships may touch the edge of the board, but cannot touch each other, not even diagonally. Additional each cell in the right grid has a number from 1 to 9. Place the digits so that each digit appears exactly once in each of the rows, columns and the nine outlined 3x3 regions. The numbers in the cages of the right grid are the sum of the cells in the cages. Cells with ship parts in the corresponding left grid can only contain odd numbers.
