IQ Forge: Word Chain
Change one letter at a time to transform the word
About This Game
Word Chain is a verbal fluency puzzle from the IQ Forge series. You're given a starting word and a target word, and must transform the start into the target by changing one letter at a time, with each intermediate step being a valid English word. For example: CAT → COT → COG → DOG.
The game challenges your vocabulary breadth and mental flexibility. Easy chains might require 3-4 steps, while hard chains can demand 6+ steps through obscure intermediate words. Finding the shortest possible chain earns bonus points. The game exercises the same verbal networks used in creative writing, wordplay, and language learning.
