Palindrome Sudoku
(Published in Daily League! The League of Extraordinary Ladies and Gentlemen & on SudokuCup.com)
Place
a digit from 1 to 9 into each of the empty squares so that each digit
appears exactly once in each row, column and 3x3 box. The digits in the
squares with the line form palindromes, i.e. they are read evenly from
both sides.
