One of my puzzles in the Quads on Parade puzzle pack hosted by Bremster and the Sudoku Skunkworks. This pack is free to download, and I highly recommend checking it out!
Normal sudoku rules apply (fill each row, column, and 3x3 box with the digits 1-9 once each).
-Quadruples: Digits in a Quadruple circle must be placed at least once in the four cells touching that circle.
-X-Sums: A number outside the grid gives the sum of the first N digits in that row or column, where N is the digit in the cell closest to the given clue.

Yes, it's just a smiley face - it's there for symmetry and happiness :)
