For game designers
Put your prototype on the table. Your testers bring their phones.
Set up your game in the browser, make a private version playable, and play it on the TV. Testers join with a QR code and install nothing.
Free to start, no payment details. You sign in with Discord, Google or Facebook. We never post for you.

- Testers install nothing
- Free plan
Where are you starting from?
Two starting points, one table
I have an idea
No finished game yet, maybe no art at all. Design your cards in the Creator from a template and a spreadsheet. When they look right, send the deck to the Builder.
Start in the Creator →
I have a finished game
Your rules and card images are ready, and you want to play it online with your testers. Upload everything to the Builder, set it up and sit down together.
Start in the Builder →Either way you end up at the same table. A deck moves from the Creator to the Builder in one click.
- Invited to a playtest? Open the Controller.
- Just here to play? Open the table.
The usual way
Testing a prototype takes more setup than it should
You have the idea, or the art and a draft of the rules. To get other people playing, you print and cut a new copy, or you build a virtual table by hand and ask every tester to install or sign up first. Every hurdle costs you a playtest.
- Printing and cutting again after every change
- Testers who drop out before the first card is dealt
- No way to look back at what actually happened in a session
GreenCloth turns the screen in the room into the table, and every tester's phone into their hand.
How it works
From a folder of images to a game on the table
- 1 / 3
Drop in your art
Drag your card images into a set in the Builder. Every file becomes a card. Set the defaults once and every card follows. There is nothing to program, and no save button: your work saves as you go.
No art yet, or no game yet? Design the deck in the Creator from a template and a spreadsheet, then send it to the Builder.

Make a private version playable
A version is a locked snapshot of your game. Packing it for the table runs on its own in the background: a text or settings change is instant, new images take a few minutes. Only the people you invite can play it.
- 3 / 3
Sit down together
Start a party and open the Display on any TV or monitor. Testers scan the party's QR code or type its six-letter code on their phones, join as guests, and you give them a seat. Everyone drags, flips and shuffles on their own phone. Hidden cards stay hidden, enforced by the server.
A version is never overwritten, so a party months later loads exactly the game it started with.

Plus
Print and play when you need paper
The Creator makes a print-and-play PDF with cut marks and a two-sided layout, so a test that needs paper does not start from scratch.
Every plan
Versions that stay put
Each version is a locked copy. Keep editing the draft while testers play the version you gave them, and retire a version without disturbing parties that are already running.
Pro
Show it to an audience
Reveal all hands and use a pointer on the Display, handy for demos and streams.

The details
Documented down to the details
The user guide covers every screen
The user guide covers every screen of the Builder, the Creator and the table, in English.
Read the guide → Three apps, one workflow
The Creator designs your cards, the Builder turns them into a game, the Account app holds your plan. The Display and the Controller are the table you play on.
Components
Builder
Creator app · browser
Sets, items, rules and versions. Import images, set the defaults once, write the rulebook with images, video and tables, then make a version playable for your testers.
Import images and configure your components
Write the rules in English and Hungarian side by side
Test with an invite code, make it playable when it is ready
Rulebook
Rulebook editor
Your languages in view while you write
Side-by-side columns, images, video and tables, and several rule documents per game if the game needs them.
Cards
Creator
Card designer · browser
Design a deck as a template plus a spreadsheet: one layout, one row per card. Send the finished deck to the Builder as a set of card images.
Fill the cards from a table, with CSV and XLSX import
Start from ready-made templates for cards, tokens and tiles
Print at home as PDF, or send to the Builder in one click

Honest limits
What GreenCloth does not do (yet)
A designer is right to ask. Here is what you will not find, so you can decide before you start.
No rules engine
Players get the components and follow your rulebook themselves, like at a real table. GreenCloth does not enforce rules or score for you. The upside: a rule change between two playtests is an edit to your rulebook, not a development job, and testers can even try a variant mid-game. If your game needs the computer to referee every move, it is not the right fit.
The Creator to Builder road is one way
A deck you design in the Creator arrives in the Builder as card images. There is no way back: an image cannot be taken apart into a template and a spreadsheet again. Keep the deck in the Creator as your source for the cards.
A draft cannot be played
To test, make a private version playable. It is packed for the table in the background: a text or settings change is instant, new images take a few minutes.
No selling yet
Public listing and sales are coming, not live. Today you test privately with your own testers, and on Pro you can run a branded game page.
No play address of your own yet
A branded game page with your name and logo is part of Pro. A branded address for the table itself is not ready.
Images, not PDF
The Builder takes PNG, JPEG and WebP images. A PDF has to be exported as images first, or rebuilt in the Creator.
Questions
What designers ask before they start
Something missing? Ask the team and the community on Discord.
Ask on Discord →Which one do I need, the Creator or the Builder?
If you have nothing yet, no game and no artwork, start with the Creator. If you already have a game and finished card images and just want it online, use the Builder. They are tools for the whole process, not two competing choices: a deck you design in the Creator goes on to the Builder.
Do my testers need an account?
Not to join a party. Testers scan the party's QR code or type its six-letter code and join as guests. A guest can only join a party. Joining a tester group needs an account: you send an invite code, they enter it in the Controller and sign in there with Discord, Google or Facebook. They never need to open the Builder.
Do my testers need to install anything?
No. The Controller and the Display run in the browser. Adding the Controller to the home screen is optional.
Do I need a credit card for the Free plan?
No. Free has no time limit and no checkout, so nothing asks for payment details. Stay on it as long as it fits your project.
Why can I only sign in with Discord, Google or Facebook?
We keep the data we hold about you small. With a sign-in you already have, there is no new password to store. We receive your name, email address and profile picture, and we never post on your behalf. Privacy Policy.
Is my game private, and whose is it?
Yes. A version is private to you and the testers you invite. Public listing is coming, and it will be your decision. Your content remains yours: see section 5.1 of the Terms of Service. Terms of Service.
Do you use my uploads to train AI?
No. We do not use the material you upload for AI training.
Do I have to program the rules?
No. Players get the components and follow your rulebook themselves, like at a real table. GreenCloth does not enforce rules, so trying a rule variant between two playtests takes a rulebook edit, not code. If your game needs the computer to referee every move, it is not the right fit.
I only have a PDF. Can I use it?
The Builder takes PNG, JPEG and WebP images, not PDF. Export the pages as images, or rebuild the cards in the Creator from a template and a spreadsheet, with CSV and XLSX import.
What is the difference between a draft, a version and public?
The draft is your working copy: you edit it, and it cannot be played. A version is a locked, private snapshot packed for the table, so your testers can play it, on every plan. Making a game public is a separate step that is coming.
Can I sell my game on GreenCloth?
Not yet. Public listing and sales are coming. Today you can test with a private group and, on Pro, run a branded page for your game.
Can my game be in more than one language?
English and Hungarian side by side, on Pro.
