• Normal Sudoku rules: Place the digits 1-9 in each row, column and box, without repeats.
• Between lines: Digits on a line are numerically strictly between the digits in the connected circles.
• Double Arrows: The sum of the digits on a line is equal to the sum of the digits in the connected circles.
• Lockout lines: Digits on a line can not be numerically between or equal to the digits in the connected circles. The digits in those circles must differ by at least 4.
• Circles split lines into segments. The nature (Between line, Lockout line, Double Arrow) of each line segment has to be deduced.
• Each sequence of 3 line segments on a line has to contain a Between line, a Double Arrow and a Lockout line.
