PLAYS CHAIN REACTIONChain Reaction is a free word-ladder game: rewire the START word into the TARGET one letter at a time, and every rung must be a real four-letter word — COLD → CORD → WORD → WARD → WARM. Four letters of the alphabet are mined, and stepping onto a word that contains one costs a life.
A puzzle where you transform one word into another by changing a single letter per step, with every intermediate step a real word. Chain Reaction adds mines, radar counts and a move budget of nine steps on top of the classic form.
Every safe rung shows a red count: how many mined letters sit exactly one alphabet step from that word's letters. Cross-reference the counts on different rungs to triangulate all four mines before you step on one.
