Anyone after a quick, casual word game should start with the free Lexatetrahedra, since players call this one brutally hard.
Lexiblox is a word puzzle played with 3D cubes. Each cube carries four letters, and each handcrafted puzzle has only one word as its solution, so you rotate the cubes until it appears. Hundreds of words are organized into 35 levels that reward logic, memory and vocabulary, and no word repeats. It is the full, paid game: no ads, no add-ons and no internet connection needed. Brian Krause, who makes it alone as Adducive, created every puzzle, pixel and sound, and it shares its concept with his free Lexatetrahedra, which has different puzzles.
Version 1.07 (3 November) made it ready for iPhone Duo, its release notes say. Adducive hasn't shown the Duo layout, so the picture here is its iPad layout.
