Chain Reaction is a daily word puzzle where you complete a chain of five words. The first and last words are given — your job is to fill in the three hidden words in between. The trick is that every pair of adjacent words must form a compound word or common phrase. For example, if the chain goes FIRE → ??? → ??? → ??? → BALL, you need words where each pair connects naturally.
