Lewis Carroll came up with the idea of word ladders.
There is only one RULE for Word Ladders:
Change ONLY one letter at a time and form a new word at each step.
For instance, you might go from COAT to SHOW as follows:
COAT, COOT, SOOT, SHOT, SHOE.
#2 Change FIRE to BALL
#3 Change WELL to DONE#4 Change WIND to SOCK
#5 Change HOME to TOWN#6 Change WOOD to LAND
#7 Change LAST to WORD#8 Change JUNK to YARD
#9 Change SHOW to CASE#10 Change LOVE to BIRD
