What you get
Cards Against Humanity, in full
42 packs, 4,661 white cards
The base set, official expansions one through six, and thirty-five more packs besides — nostalgia, college, absurd, the lot. Pick the ones your group can handle before you start.
Your hand is yours
Cards are dealt to your own screen. Nobody leans over, nobody sees what you nearly played, and nobody has to hold a fan of cards in one hand and a drink in the other.
The Czar reads them blind
Submissions arrive shuffled and anonymous, so the Card Czar judges the card rather than the friend. Reading them out is still your job.
No shuffling, no packing up
No sorting cards back into a box at one in the morning, no realising the black cards got mixed in. Start a room and deal.
Three to ten players
Share a five-letter code and everyone is in from any browser. Works around a table and works for the friend joining from another city.
Properly licensed
The card content comes from the official Creative Commons BY-NC-SA release. We are not scraping someone's fan site; we are using what the publisher put out.

Questions
Frequently asked
How do you play Cards Against Humanity?
Each player holds ten white cards. One player each round is the Card Czar and reads out a black card with a question or a blank in it. Everyone else submits the white card they think answers it best, face down. The Czar reads the combinations out and picks a favourite, and whoever played it takes the black card as a point. The role rotates, and most points wins.
How many cards do you get?
Ten white cards in hand, refilled to ten after every round you play into. Across 42 packs there are 4,661 white cards and 1,041 black ones in the pool.
Is it free?
Yes. No payment, no account, no app. Start a room in the browser and share the five-letter code.
How many players do you need?
Three to ten. Three works but the Czar only sees two submissions, so five or more is where it gets good.
Can you play with 2 people?
Not really — with two, one of you is always judging and the other is always submitting, so there is no contest. Three is the practical minimum.
