Caseboard Kit — Mystery Game Art & Web Starter

Build a small browser mystery around evidence your players can connect. Caseboard Kit combines 24 original illustrations with a working HTML/CSS/JavaScript investigation board. Try the short example case above before buying.

The $3 bundle

• 24 distinct evidence illustrations: lantern, cabinet, ticket, rain cloud, note, clipboard, key, clock, camera, envelope, map, compass, footprints, magnifier, book, cassette, telephone, newspaper, flask, parcel, boat, lock, pin and tag.
• Editable SVGs plus transparent 512 × 512 PNGs. These are 24 designs in two formats.
• A dependency-free web board with draggable cards, keyboard movement, clue connections, multi-link deductions, browser saving and JSON save import/export.
• A responsive reading view with the same clue-linking controls.
• Complete JavaScript source, a written six-clue example case, integration notes and a solution guide.

How you use it

Open the included index.html to try the example. Edit case.js to supply your story, clues and deduction rules. Use the illustrations in the included board or in your own game. No subscription, paid API, external library or build step.

Scope: a small web starter, not a Godot/Unity plugin or a visual no-code case builder. Basic HTML/JavaScript editing is needed to customize a case. Browser storage can be blocked by privacy settings; export save is the fallback. Best experienced on desktop; reading view supports smaller displays.
