WordGolfRules

Word Golf, also known as Doublets or Word Ladders, is one of many games invented by Lewis Carroll. The objective is to change one word into another, one letter at a time, in as few steps as possible. Every changed letter must result in a valid English word.

To start, choose two words of the same length, preferably three to six letters. The starting and ending words should be related: antonyms, synonyms, or members of a category, such as animals or personal names.

Here is an example, changing BLACK to WHITE:

BLACK
SLACK
STACK
STALK
STALE
SHALE
WHALE
WHILE
WHITE
