It's more of the same if you have played the previous installments of this series.
Main changes are that now there's this sound effect when you connect letters, but because there's no way to change the settings in-game, if you want to lower the volumen you have to do it directly from your computer.
Also, now there are a few more achivements aseide from "do all the puzzles". There's one caled "No Hint" that because of it's wording may be confusing, but you don't get it for finishing the game without using hints, but by spending all your hints at least once.
Once again, good game for getting easy achievements and trading cards, but only if you get the game as part of a bundle for a really cheap price.

Me lo pase bien al inicio, las ultimas 2 categorias se fueron al chancho con la dificultad
