Lots of ads. The only reason to play over the other rip off games is to challenge yourself with past games and see how far you can get. Imagine my dismay in finding two games that were unsolvable. All letters in correct spot but one and even the game says no remaining letters form valid words. Maybe some update corrupted past games. Maybe programmers were just threatened by my genuis and sabotaged me. Too bad. I assume their incompetence is reflected in all the games that they advertise as well.
