*** TODAY'S PUZZLE ***
An absolutely gorgeous sudoku tonight from FIT7Y about which the only disagreement seems to be regarding its difficulty! Some say it's a mere bagatelle (2/5), others have used the word "Brutal"... However you approach it, it's really clever and a lot of fun to solve. Enjoy!

Play the puzzle at the links below:

Rules:
Normal sudoku rules apply. (Place the digits 1-9 once each into every row, column, and 3x3 box). A cell is "friendly" if its digit matches its row, column, or box number (boxes are numbered from left to right and top to bottom ie in normal reading order). Draw a circle in every friendly cell that doesn't already contain a circle. If a digit N appears on a circle, then it appears N times on circles.
