I like several things:
--- on/off feature for errors.
--- hints for just one letter or for a word.
--- displays the word youre on across the top of the keyboard display.
--- displays the letter played on keypad like messenger.
--- automatically goes to the next logical word to find or you can turn that off.
I tried several crossword games before spending money on more puzzles.
Lots of fun!
