It currently says "...fall in love in with Sudoku". There's an extra "in" there. The other issue with tthat phrase is that unless the trailer grossly misrepresents how you play the game (I've yet to play it myself), it is nothing like Sudoku at all. The game is actually similar to Kakuro (often listed as Cross Sums in publications). Both of these are similar types of fill in the number puzzles, but they use different logic and clues.
