Charlie i think you mis-understand the rules. You can only change one letter, you cannot add or remove them. I.e. Cake=Cape
Where is the misunderstanding R-A-U-N-C-H to C-R-U-N-C-H (First C replaces the A the other 5 letters are still there - nothing added or subtracted)
I was more thinking of the LANCEL to UNLACE where you have done a bit of everything, added the U, but removed the L and moved the other letters.
Yes that's right, that is what the game is about where is the problem L-A-N-C-E-L to U-N-L-A-C-E (The U replaces the first L and the other 5 letters are still there - nothing added or subtracted) like fool to loon (lol)
