What's New on CacheSleuth

The Big Picture

Site-wide improvements that apply to every page.

Tools & Upgrades

Every tool was individually re-thought during the redesign with the goal of making it the best version of itself. Every tool also now has worked Examples built in, which was not on the old site.

• Multi Decoder

  Rewritten from the ground up. Paste cipher text and the decoder runs every supported code at once, with separate slots for keywords, alphabets, and number sequences. Results are now ranked so the most likely "possible words" float to the top, and a filter lets you hide every section that did not produce a result. There is also a Share button that builds a link with your exact input and settings baked in, so you can hand it to someone else and they land on the same view. The list of supported ciphers is added to periodically.

• Wherigo Solver

  Drop a .gwc cartridge and the solver decompiles the Lua code, scans the zone data, and ranks the most likely final coordinates with a confidence score. Reverse Wherigo presets for the Waldmeister and day1976 cartridge formats are included.

• Multi Encoder

  Brand new for the redesign. Type a plaintext message, optionally provide keywords or a custom alphabet, and the encoder produces every supported cipher, code, and number-base representation at once. Output is grouped by family with a search filter, copy button per row, and a Share Link that round-trips back through the Multi Decoder.

• Geocache Viewer

  Multiple input methods are supported: drop a saved cache page, paste the raw HTML, or use one of the browser extensions or bookmarklets that send the page directly from geocaching.com into the viewer. The viewer reformats the page into a cleaner layout and surfaces details that the live site does not show. Everything runs in your browser.

• Coordinate Converter

  Converts between DD, DDM, DMS, UTM, MGRS, Plus Code, Maidenhead, Geohash, GeoHex, Geo3x3, NAC, Mapcode, OSGB, Mercator, and both Reverse Wherigo formats (Waldmeister and day1976) at the same time. Includes elevation lookup, a map view, and one-click links out to Google Maps, OpenStreetMap and other mapping services. The converter also runs as an embeddable iframe on other pages so you can get full coordinate conversion functionality in multiple places.

• Codes & Symbols

  Over 266 code tables, most of them interactive so you can type your own message and see every variant render at once. Filter by name, or pick "Show All Codes" to render a single phrase across every monoalphabetic code on one page, which is useful for figuring out which code a puzzle is using.

• Geocaching Quick Search

  A new homepage card and a dedicated sidebar mode let you jump to a cache page, log a find as any log type, look up a user's profile, hides, trackables, or stats, search FTF or recently published caches by region, or open your own dashboard.

Quality of Life

Smaller refinements throughout the site.

• Smart search bar. Paste coordinates in any notation and the search bar routes you to the Coordinate Converter. Type a cipher name and it opens the right tool. Partial matches show an autocomplete dropdown.
• My Puzzle Texts drawer. A cross-page scratchpad for ciphertexts, keys, custom alphabets, and any other text you want handy across tools. Saved locally in your browser, with Export and Import for backups. Click into any tool field and press Insert, or use Pick a field to choose a target from a list. Open it from the button in the sidebar.
• Reorganized sidebar. Tools are grouped by what they do, with quick-jump panels for codes, geocaching links, and translations. You can quickly filter the results here too and just press enter to go to the first result. The mobile drawer mirrors the desktop sidebar exactly.
• Inline "Learn more" accordions. Homepage tool cards have an expandable summary of what each tool does, so you can review the description without opening the tool.
• Featured tools shuffle. The homepage spotlights three tools at random. Press "Reshuffle" to swap in a different set.
• Embeddable tools. The Coordinate Converter can run as an embedded widget on the homepage and inside other tool pages on the site, with all of its features intact.
• Shareable tool URLs. Many tools encode their input into the URL, so you can copy the address bar to share or bookmark a specific puzzle state.

Recent Updates

Improvements landed since the redesign launched.

• Auto coordinate chip on every text field

  When you paste or type text into a tool that contains a recognizable coordinate (DD, DDM, DMS, UTM, MGRS, Plus Code, OSGB, Reverse Wherigo, What3Words), a small "Possible coordinate" chip appears below the field with a copy button and a one-click link to open it in the Coordinate Converter.

• Two upgraded time-of-day tools for puzzles

  Time Decimal is brand new: enter one or more times of day and it returns total seconds since midnight, percentage of the day elapsed, and the two-digit value used in coordinate-from-time puzzles, with a concatenated-digits summary at the bottom for DDM reading. Clock Angle was rewritten alongside it: a multi-row table now accepts seconds, exposes Standard vs Raw (180° vs 360°) modes, shows the clockwise and counter-clockwise sweep, and includes the same concat-digits summary.

• Multi Decoder polish round

  A searchable Focus combobox lets you isolate just the cipher you care about. Sections are now themed and alpha sorted, with per-card descriptions and a new Syllables card for text analysis. Word detection feeds the Vigenère auto-solver. Multi-token base conversion and a walking-base decoder were added.

• Geocache Viewer: convert every coordinate at once

  The Coordinate Converter tool inside the viewer used to handle one coordinate at a time. It now harvests every recognizable coordinate from the pad and renders a full DD/DDM/DMS/MGRS/UTM card for each one, so you can compare multiple candidates side by side.

• Nine ciphers now have their own pages

  Codes that previously only existed inside the Multi Decoder are now standalone tools, each with worked examples, share links, and their own URL so you can deep-link straight to them: Base32, Base58, DTMF, Nihilist, Numbers in Alphabetical, Numerology, Planet, Postnet, and Segment Display (which also gained an encode mode and a supported-characters panel).

• Tupper's Self-Referential Formula

  Renders the bitmap that Tupper's inequality plots for any 543-digit (or larger) k value, and goes the other way: paste or draw a bitmap and it computes the k that draws it. Useful when a puzzle hides text or a sketch inside a giant number.

• More text-options on every input

  Remove Newlines, Split Into Lines, and Normalize Spaces are now available alongside the existing case, filter, find/replace, and group buttons under any tool's text input.

Languages

CacheSleuth is now available in 10+ languages. Language names appear in their native script in the footer dropdown so you can find yours without scanning English labels. The old site used the Google Translate widget, which often broke JavaScript and stopped page features from working. The new translation runs through CacheSleuth's own translator instead, so tools keep working in any language. Translations are produced by a machine model, so some are still rough.

If you spot a translation that looks wrong or awkward, please report it on the translation feedback form. The form lets you correct several strings at once, and the fixes are applied as manual overrides that the whole site picks up on the next visit.

What Stayed The Same

• Every tool from the old site is still here, just better organized and easier to find. Each one has been enhanced where possible with new features and improvements.
• Tool URLs are unchanged where it was practical to keep them, so your bookmarks should keep working.
• Nothing requires an account, and nothing tracks you across the site.
• It is still free and ad-free.
