Basically, you are given a word, and the goal is to change one letter in the word so that it will be another word. For example, the first word was "Cork". The next user then changed one letter in the word, to make it "Pork". In addition to changing one letter in the word, you can also rearrange the letters to make a word. For example, wim posted "Caris". I then changed the "i" to a "y", and swapped the letters around to make it "Scary".
You can do both, or just one.Do you have to do both, or can you just change a letter or move it around.
