Tips on Solving Valentine's Sudoku

  • Remember that the main rules you will use are the same as standard sudoku: looking to see where in a region each number can go, and when there is only one option, placing it
  • Noting down the candidates for each square, and where there is only one left, placing it
  • Remember that the two grey regions that form the heart are not there for decoration, they are an integral part of the puzzle. The key to solving the puzzles will be the extra information that they provide. This will also be the hardest part, as the regions will be unfamiliar.
  • If you get stuck, it is most likely that there is information provided by the grey regions that you are not using. Remember, if a number is placed in a light grey region, then it cannot appear in ANY other light grey coloured square, and similarly if a 9 appears in one dark grey square, then it can be removed as a candidate from all the other dark grey squares. This is the key to solving Valentine's Sudoku
  • If you've been brought this book as a gift, then perhaps your loving partner would like to make you a nice tea or coffee whilst you solve and feed you chocolates, just to help you concentrate on solving the puzzle of course!
