Fans of cryptograms will certainly like Cryptograma which offers puzzles in both English and Spanish. The puzzle here is implemented with a slick flash interface and instead of a letter for letter substitution, each letter is represented by a different symbol. Highlighting a symbol and pressing a letter key automatically substitutes that letter for any occurence of the symbol. There also seems to be a fairly large stock of quotes, so that you can play multiple times with different puzzles.
