• Normal sudoku rules apply.
• Fog of War rules apply: placing a correct digit in the grid will reveal the surrounding cells.
• Lines are Between Lines, Modular Lines, or Palindromes. The identity of each line must be deduced. Lines never cross or branch in this puzzle. Therefore, if two line segments enter the same cell, those line segments must be connected.
• If a line is a Between Line, the values of all digits on the inside of the line must be strictly between the values of the digits on the endpoints of the line.
• If a line is a Modular line, each consecutive group of 3 cells on the line must contain one digit from each of the following sets: [1,4,7], [2,5,8], and [3,6,9].
• If a line is a Palindrome, it must read the as the same sequence of digits starting from either end.
