Show HN: Blank White Cards – Global Drawing Party Game

G’day HN, this year I've been remaking my online adaption of the classic party game 1000 Blank White Cards (https://en.wikipedia.org/wiki/1000_Blank_White_Cards)

I started this project in 2019/2020, originally as a drinking game for house parties, but it transformed into a way for my friends to keep in touch during the long Melbourne COVID lockdowns.

Essentially anyone can draw and submit cards to a common ‘Global Deck’. You then pick them up and do what they say (or not). The whole premise of this game is that there are no concrete rules - they’re forever evolving.

Over the years people from around the world have contributed nearly 500 cards. I have to say I’m impressed that it’s probably 80% high vs 20% low quality content. The art ranges from awesome to hilariously crude and the gameplay is somewhat coherent - but always hilarious.

There are global servers for multiplayer custom games where people can jump into the same session and move cards around a bit more like a real tabletop game. I’ve recently added support for Discord Activities (https://discord.com/discovery/applications/13895086247742013...) so you can play directly inside a call.

Start with a blank slate and save your custom deck creations to re-upload in later games. Coming up on the feature roadmap is a proper deck builder/editor mode.

It’s been a really interesting challenge trying to create a game that has no rules, but I’ve learnt a lot in the process. My biggest takeaway is that human creativity has no (lower) bound :)

I hope you have as much fun playing it as I do making it, and that one day we’ll reach the magical 1000 card mark.

P.S. this wouldn't have been possible without great open source software like + https://boardgame.io/ + https://wiredjs.com/ + https://www.fiala.space/atrament/ = https://github.com/mcteamster/white

Very nice.

Really clean.

It looks like you are recording the sessions with Microsoft Clarity. You mentioned it is anonymous, but do you really need heatmaps and session recordings?

Thanks! Great question - the heatmaps and traces really help with refining gameplay UX like identifying dead click areas and reducing the number of interactions for popular functions.

Of course any client-side RUM can only give partial insights. Always open to hearing any direct feedback suggestions or improvements.
