hi , I have developed a wordchallenge cheat in java. It worked fine for me and got 55.000 and first of my rank. The bad think is that it removed my rank without cheating, and it was not too bad( 13.000 Spanish).
The code anyway is quite interesting:
-I used some collections features. Good for practicing.
-Robot class to output the generated anagrams to the keyboard port. It´s funny when starts typing all the words into other programms(f.e. eclipse) if you don´t switch the window fast enough , but you have 3 seconds to switch.
Note: my dictionary(list of words) was not very good , look for a good one with plurals ,conjugations(go, goes, went,gone) . The bigger the better.
