Connect 4 Cache Builder

Build a Connect 4 geocache, players beat the computer to unlock your coordinates or keyword.

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

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.

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.

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://.

I understand this cache 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.
