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 nonogram, also sold as picross, hanjie or a griddler, is a grid with a run of numbers beside every row and above every column. Each number is a block of filled cells, in order, with at least one blank between blocks. Work out where they go and a picture appears. Pick one of two ways to use it below, then set what solving reveals.

Your puzzle

Shown to players as a link to your cache page.

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

How the puzzle works

One to ten, solved in order. The reveal comes after the last one.

A submission that is wrong costs a heart, and players are told how many cells are off but never which ones. At zero hearts the puzzle starts over rather than the cache ending.

On solve, reveal

Shown only after a player finishes. Reveal either the final coordinates or a keyword, not both.

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://.

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