Big Hits

Normal sudoku rules apply.

There are 9 doubler cells to be located n the grid, one in every row, column and box, and each containing a different digit. The value of a doubler cell equals its digit multiplied by 2. The value of any other cell equals its digit, as usual.

Values do not repeat on a beige hitline (though digits might.) The VALUE of a circled cell indicates how may cells along its line have VALUES that match their position number along the line, starting from the square end (which is position 1.)

Eg: If a line has the values 1 3 16 4 5 (in that order,) then the 3 would be circled, because three cells have values that match their position number; 1 is in the 1st position, 4 is in the 4th position, and 5 is in the 5th position.
