Nintendo today launched Crosswords DS, a new title for the Nintendo DS where you'll use the stylus to solve crossword puzzles, also featuring mini-games like Wordsearch and Anagrams. Because you write all your answers directly on the touch screen with your stylus, there's no need for erasers – just write your new answer over your old one. Crosswords DS also includes a sophisticated hint system if you get stuck. Just tap the Hint button with your stylus and choose to receive another clue, reveal a hidden letter or solve the whole word. A trailer is now available.
