A great Valentine's Day gift idea for your wife who loves sudoku could be a personalized sudoku book. You could create a book of sudoku puzzles with personalized messages on each page, such as "Happy Valentine's Day" or "I love you". You could also add some romantic quotes or messages between the puzzles to make it more meaningful. Another idea is to get her a fancy sudoku board with wooden number pieces that she can play her games on. You could even make it more romantic by setting up a candlelit dinner while she's solving her puzzles or give her a surprise gift box of her favorite chocolates or snacks to munch on while she plays.
Or you can get her a star map with the date of your first kiss.
