Turn one word into another, one letter at a time!

Do you have a good vocabulary? Do you think fast? In "Word Challenge"
the goal is to transform one word into another, changing only one letter at a time, and every resulting word must have meaning!

Get ready for a fun challenge! There are 7 levels, with 10 random words each!
You can play casually, or fight bravely to get your name in the top players ranking!

There are four main rules:

1. You can change one letter for another;
2. You can insert a letter anywhere in the word;
3. You can remove a letter from the word;
4. The entered word must make sense!

Are you ready???
