Verbose Rules:

• Normal Sudoku rules apply. Digits 1 through 9 must appear once in each row, column, and box.
• Normal Renban rules apply. Purple lines are renban lines. Digits along each renban line must be a set of consecutive digits in any order, and must not repeat. Renban lines continue into (or through) cells where the line is obscured by a large circle.
• Normal Double Arrow rules apply. Grey lines are double arrow lines. The sum of the digits on a double arrow line is equal to the sum of the two digits in the circles that are connected by that line. Digits may be repeated on line-circle combinations.
• Normal Difference rules apply. Clues in circles between two cells indicate the difference between the digits in those two cells. Not all difference clues are given.
• Normal Quadruple rules apply. Circled digits where four cells meet must be present as values in those four cells.
