Wordit! - unique word game 1.4

The game: You get a pair of words. In order to win, you have to transform the former word into the latter one in the least number of steps possible. A lower average of steps means more efficient solving. The rules: On each step, you have to transform the previous word by one of the following: 1. Changing the letters\ position. For instance, the word \team\ can be transformed into \meat\, \tame\ or \mate\. 2. Adding/deleting one of the letters. For instance, the word \mate\ can be changed to \mates\ or \mat\. Thus, \meat\ -> \mates\. 3. Changing one of the letters: \team\ -> \teem\ Also, you can do all three actions simultaneously: \team\ -> \meets\.
