• Normal sudoku rules apply. Place the digits 1-9 once each in every row, column, and 3x3 box.
• Arrows: Digits along an arrow sum to the digit in the attached circle.
• Between Lines: Digits on a line must be strictly between the digits in that line's circled endpoints.
• Palindromes: Digits along a thick palindrome line must form the same sequence of numbers when read starting at either end.
