Welcome to the world of acrostics! An acrostic, also called a crostic or double crostic, is a cousin of crossword puzzles, with clues and answers whose letters are rearranged to form a quote from a famous (or not-so-famous) author. If you're familiar with acrostics, you will quickly see how convenient they are on the iPhone, because letters are automatically copied to the correct place as you type them in.
Crostix is a free version of our Crostix Pro application, containing sample puzzles from our library. Try them out, and if you like them, get the full version, with 150 puzzles, from easy to fiendishly hard, or just buy more in Crostix using in-app purchase.

These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
