Samurai Sudoku

BATTLESHIPS

The rules for Samurai Sudoku vary only slightly from the standard sudoku rules. The 9x9 sudoku at the centre of the X shares four of its 3x3 boxes with those of the outer sudoku. None of the 9x9 sudokus can be solved individually, you must crossreference between the intersecting grids.

Find where the fleet of ships shown are hidden in the 10 by 10 grid. The numbers to the right of and below the grid indicate how many of the squares in that row are filled in with ships or parts of ships. The ships do not touch each other, even diagonally. Some squares have been filled in to start you off.
