Chain Reaction Cache Builder

Build a compound-word chain puzzle cache with a sharable play link.

Free, just a username and passphrase, no email. Caches you build show up in My Caches so you can reopen and edit them without hunting for the edit link, and watch plays and wins. The same account syncs My Puzzle Texts across devices and manages your short links.

My Caches

Chain Reaction is a word-chain puzzle. You pick 6 to 8 words where every neighboring pair makes a compound word or a common phrase, like SESAME to STREET to CAR to POOL to TABLE to TENNIS to BALL. Players are given the first and last words plus one letter of each hidden word, and they may only guess a word next to one they have already solved. Wrong guesses cost a heart and give away another letter. Linking the whole chain reveals your final coordinates or keyword. The chain and the final answer stay on the server, so nothing is hidden in the page for a player to peek at.

Anything you create here is public to anyone with the link, and you are responsible for what you publish. Keep a copy of your edit key, it is the only way to change or delete your puzzle later.

Puzzle mode

One fixed chain A new chain every day

6 to 8 words, 3 to 10 letters each, no repeats. Every neighboring pair should make a compound word or a familiar phrase. Players see the first and last words; the rest are hidden. "Surprise me" fills in a ready-made chain that you can still edit.

3 to 10 wrong guesses allowed across the whole chain. Players can start over after running out.

Image URL (optional)

Where can I host an image for free?

Paste a direct https:// link to an image. Free image hosts that give a direct link include ImgBB, postimages.org, and Cloudinary. A geocaching.com image link works too. The link must start with https://.

I understand this puzzle is public, contains nothing sensitive or inappropriate, and I am responsible for its content. I also understand that caches which sit unused are removed automatically: one that is never played is deleted 30 days after it is created, and one with no plays for two years may be deleted.

Keep your cache in play to keep it live. Share the play link so people visit it; unused caches are cleaned up over time.
