Word Chains are a sequence of words where you attempt to change one word into another word. The rules are that at each step you can add a letter, remove a letter or change one letter to another, in each case without altering the order of the letters, or you can make an anagram of the letter. At every stage you must have a valid English word.
For example, if you have the word STOP you could make
SOP by removing the T
STOPS by adding an S
STEP by changing the O to an E
POST by making an anagram
And of course there are many, many others.
Firstly, can you change LATE to REGAL in three steps.
LATE goes to LATER by adding an R
LATER goes to LAGER by changing the T to a G
LAGER goes to REGAL by anagramming
