Create an 18 card Spooky themed game.
Finalists due Hosted by Dustin Hendrickson
Board Game Design Tools · Online Playtesting
Design your components, playtest them on a full virtual tabletop, and learn from every session, all in your browser. When a card needs fixing mid-game, change it once and every copy updates. Your testers join with a room code, and their feedback lands in your project, not in a dozen chat threads.
Free plan. No credit card.
Invite your playtesters. They don't need to install anything or create an account.
Made by Dustin, board game designer & developer.
Your project, one drag away
Every component and deck in your project sits in the sidebar. Drag one onto the table to place it.
Right-click to edit
Right-click a piece from your project and open Edit Project Component, over the table. Save, apply, and every copy updates.
Draw straight to your hand
Hover a deck and press 1 to 9 to draw that many cards into your private hand.
Host tools on the table
Snap points, zones, markers, text labels and stickers, each on its own key.
A real prototype on a real playtest table. Hover or tap the numbers, or click the screenshot for a closer look.
Every designer knows these. Here is what DDD does about each one.
Edit a component once and Apply to Table updates every copy: on the table, inside decks and stacks, and in players' hands. For a bigger revision, bring in a CSV of your changes and play the next round.
They don't have to. Players join with a room code and a name, in the browser on a laptop, tablet or phone. No download, no account, nothing to buy. Voice chat and private hands are built in.
Players rate fun, difficulty and rule clarity during the game, and every submission is saved with their name. Close the room and the session, its action log and its feedback are logged to your project automatically.
Playtest Analytics shows which cards get drawn and played, how the dice land, and the trends across sessions. Session Replay lets you scrub back to the exact turn that went sideways and see the whole table, hands included.
Components, decks, custom masks, rulebooks and table setups live together in one project. Already built pieces somewhere else? Bring them in from a spreadsheet, a Dextrous file, or The Game Crafter (Pro).
Turn your components into print-at-home sheets with the Print & Play Maker (Pro). Find publishers looking for games like yours, and attach a playable table setup to your pitch so they can try it in a click.
Free forever for 2 projects and 6 players a room. Pro unlocks unlimited projects, 10-player rooms, Playtest Analytics, Session Replay, the Print & Play Maker, persistent rooms and the public lobby.

Build at the table
You don't have to fill in a form for every piece before anyone can play. Start with your art and an empty table, and shape the game where you can see it working.
As the host, drag an image file from your computer onto the table. Name it, choose Card, Token, Board, Dice, Coin or Bag, and it becomes a component in your project, placed where you dropped it.

Create & Edit Component
Edit Project Component opens in a window over the table. Set the back, the size, the shape and the rest, then save. You never leave the room.
How it worksPull a plain card, token, board or bag from Generic Objects, size and color it on the table, then right-click it and save it as a new Project Component.
How it worksAs the host, place snap points, draw zones and turn on grids right on the table, so pieces land where they belong for everyone.
How it worksSave the whole arrangement as a Saved Table Setup. Load it to start the next playtest, or switch setups in the middle of a session.
How it worksBuilding a big set? Forms are there when you want them: the Component Wizard makes a whole deck from a folder of card images with Bulk Cards, and CSV, JSON, Dextrous, Tabletop Simulator and The Game Crafter imports bring in work you already have.
ImportsChange it mid-game
Every piece on the table is a live copy of a component in your project. A tester spots a problem, you fix the component from inside the room, and one click puts the fix in front of everyone.

Two dimensions, on purpose
A board game is mostly flat things on a table. Keeping the table 2D is a choice, and it is why your group can join from more devices and spend the session on your game instead of the controls.

For your game
Choose your kind of game to find the tools for your next playtest.
Test how your card pool feels in sealed play. Choose the cards per pack, rarity tiers, and odds, then let players open randomized packs at the table.
Let players build their own decks and test different combinations. They can save a deck to their computer and bring it back to rooms where you allow personal decks.
Build different decks from the same card library and group tokens into stacks. Update a card once in your library and every deck using it gets the change.
A long game can wait until next week. Players can save the table, including every player's hand, to a sealed file and resume from the same setup when the group returns.
Lay out your game once and reload it for the next playtest. Pieces, zones, snap points, and room settings come back together. Pro adds more setups and public sharing.
Watch a recorded session back to understand a turn you missed or revisit a tricky moment. Follow moves and draws on the timeline, then save a moment as a setup to test it again.
Give pieces a clear place to land on your board. Snap points can accept specific pieces, rotate them, or flip them as they arrive, so players spend less time lining things up.
Make spaces for hands, discard piles, hidden information, or neatly arranged pieces. Set how each area behaves without writing code.
Set real dimensions for your cards, boards, and tokens so you can check how everything fits. Use built-in shapes or draw your own outline in the Mask Editor.
Send your pitch to a publisher accepting submissions and attach a playable setup. They can try it in a private room while your project stays private. Track replies and status in My Pitches.
Take your prototype to an in-person playtest. Make a printable PDF at the right sizes, with cut lines and bleed marks. Save the layout so you can generate a fresh copy after changes.
Put a playable version of your game in front of community testers and judges. Get feedback through the competition, and display any awards on your designer profile.

A card is too strong? Edit it from the table and sync the copies already in play. For a bigger revision, bring in a CSV of your changes and try another round.
Check the draws, dice results, and player feedback after the game. Designer Insights highlights patterns worth investigating. Turn on recording to replay a moment you want to understand better.

I make board games too. I built Dustin's Designer Den so I could change a card, try another round, and keep track of what still needed work. I test my own games here every week, and I want it to be useful at your table too.

I design, build, and maintain DDD myself. I've spent over 20 years working in software, including commercial video games, and I design and self-publish board games too.
I use AI tools to help with development and drafts of some help articles and site copy. Earlier drafts included help from Claude Sonnet by Anthropic. I review and revise that content as the site grows.
AI is part of my development workflow. DDD does not send your projects, game designs, or stored data to AI models. AI is not a feature of the app.
