The object here, is to make a completely new word by changing ONE letter in the previous word. You can rearrange the letters as well. For example ...
STARS can become START by swapping the S with a T. Or ...
STARS can become RATES by swapping the S with an E and rearranging the letters.
Just be sure to only change one letter. If you get stuck, simply post a new word. Feel free to jump in anywhere and play along, or Post your own word starter.
Enjoy, and have fun ...
