Sign in to save this cache to your account

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
Do not put sensitive, personal, or inappropriate content in a cache. 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 cache later.

Play your own cache before you publish it

Settings that look fair in this form can be brutal, or trivial, in the field. Finish the game yourself, start to end, on the kind of device your finders will use, and check that the difficulty, timers, hints, wording, and the final reveal all behave the way you intended. Every cache you create here comes with a play link and an edit link, so you can test it, tune it, and test it again before anyone else sees it.

A Connect 4 cache hides your final location behind a game. Players open your link and play Connect 4 against the computer. When they get four of their pieces in a row, up, across, or diagonally, before the computer does, the page reveals your final coordinates or a keyword. The game runs on the server, so there is nothing on the page to peek at.

Cache

Only the site admin can see this, in case they need to reach you about your cache. Never shown to players.

Where can I host images 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://.

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

Play as a preview

Preview links are demos only, they cannot be shared or used as a live cache.
