Number Slider Cache Builder

Build a sliding tile puzzle cache. Solve the classic 15 puzzle to unlock the reveal.

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

Number Slider is the classic sliding tile puzzle. Players slide numbered tiles around an empty square until they read in order, 1 to the top tile, left to right, top to bottom. Solve it and CacheSleuth reveals the final coordinates or a keyword. Every win is checked on the server, so the answer never sits in the page.

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.
