Chain Reaction Words
Chain Reaction Words is a free online word chain game (shiritori-style): a themed category is set, and each word you type must start with the last letter of the previous word — tiger → rabbit → toucan → newt. Beat a per-word countdown without repeating or breaking the chain. Play the shared daily category or endless mode. No install, no account — play instantly in your browser.

How to play Chain Reaction Words
- A themed category (Animals, Countries, Foods, Sports, Fruits & Veg or Cities) and a starting word are set for you.
- Type a word in that category that begins with the last letter of the previous word — the required letter is shown in big.
- Each valid word extends the chain and scores points; longer words and quick answers score more.
- You can't reuse a word, and you must beat the per-word countdown timer.
- A repeat, a non-matching word, an out-of-category word, or running out of time ends the chain.
- Daily mode gives everyone the same category and starter; endless mode is a fresh random start each round. Share your chain length.
