Card Game Prototyping Software, Built for Fast Iteration

Build a deck, playtest it online the same afternoon, and revise before your testers leave the table. The design-test-iterate loop, minus the paper cutouts, the Photoshop, and the Tabletop Simulator setup.

Stop stitching together five different tools

Most prototypers juggle Google Sheets for data, Photoshop for layout, TTS for testing, and a broker for printing, and every handoff loses fidelity. ShuffleKit collapses the whole pipeline into one project.

  1. 1

    Sketch the game

    Start with AI brainstorming, a CSV import, or a blank canvas. Define properties once, reuse everywhere.

  2. 2

    Build the deck

    Pick from 35 template packs or build your own design. Bulk-edit cards in a spreadsheet view.

  3. 3

    Test it, then ship it

    Iterate on the online playtable in real time, then export to TTS, Roll20, PDF, or print on demand via The Game Crafter.

One project, the whole prototype

Data-driven cards

Cards are rows in a database. Change a property, every card updates. No copy-paste between tools.

AI design assistant

Brainstorm mechanics, generate cards, balance costs, with an AI that reads your project context.

Online multiplayer

Built-in playtable for up to 6 players. No install, no licence, no setup.

Export anywhere

Tabletop Simulator spritesheets, Roll20 decks, print PDFs with crop marks, all from the same project.

Print on demand

Direct integration with The Game Crafter. Click publish, get a real printed deck shipped.

Version history

Snapshot cards, decks and rules docs and restore any of them, with an automatic snapshot before every import.

Frequently asked questions

Everything you need to know before getting started.

Still have questions? Contact us

What can I do for free?

The free plan covers full design, AI card generation with a monthly allowance, and online playtesting with up to 6 players, for one project of up to 120 cards. Paid plans add unlimited cards, more AI credits and export to PDF, PNG, SVG, Tabletop Simulator and Roll20, with printing through The Game Crafter on Indie.

Can I import an existing prototype?

Yes. Import card data from CSV, Excel or JSON, and designs from a PDF with one card per page or an Illustrator or Photoshop file, which come in as editable layouts. ShuffleKit matches your columns to fields as they come in.

Does this replace Tabletop Simulator?

For most card-game prototyping, yes, and faster. For 3D physics or non-card components, no. ShuffleKit also exports cleanly to TTS if you need both.

Is my data exportable if I leave?

Yes. Card data exports as CSV or JSON on every plan, and paid plans also export every card as images and print PDFs. No lock-in.

How long does it take to build a prototype?

A simple deck takes about 30 minutes from scratch. A full balanced TCG can be prototyped, playtested, and printed in a weekend.
