Theme: GP = Grandmaster Puzzles
Author/Opus: This is the 236th puzzle from Thomas Snyder aka Dr. Sudoku.
Rules: Standard Sudoku rules. Also, if a gray circle is given between two adjacent cells, then the two numbers in those cells must be consecutive (i.e., differ by 1). Not all gray circles are given; adjacent cells without a circle may contain either consecutive numbers or nonconsecutive numbers.
Answer String: Enter the 6th row from left to right, followed by a comma, followed by the 7th row from left to right.
Time Standards (highlight to view): Grandmaster = 3:45, Master = 7:00, Expert = 14:00
