You’re sitting around a sticky coffee table. It's late. Your friend just played a card so offensive it made the room go silent for three seconds before everyone lost their minds. That’s the magic of this "party game for horrible people." But while you’re busy debating if "A cooler full of organs" beats "The blood of Christ," you might be sitting on a literal secret. The Cards Against Humanity easter egg isn't just one thing. It’s a series of hidden jokes, physical compartments, and digital rabbit holes that the creators, Max Temkin and his team, tucked away for the obsessives.
Most people just rip open the box and start playing. They miss the texture of the cardboard. They don't look under the lining. Honestly, it’s kinda hilarious how much effort the CAH team puts into things 99% of players will never see.
The Secret in the Bigger Blacker Box
If you bought the "Bigger Blacker Box"—the massive storage case meant to hold every expansion—you probably thought it was just a fancy empty vessel. You’re wrong.
There is a legendary Cards Against Humanity easter egg hidden in the very structure of that box. If you take a utility knife and carefully (seriously, be careful) cut into the bottom lining of the box, you’ll find a single hidden card. It’s usually tucked behind the foam or embedded in the cardboard layers of the lid or the base. In the original version of the box, the card was literally "The Biggest, Blackest Dick."
Why do this? Because the creators think it’s funny to make you "vandalize" your expensive purchase to find a joke. It’s a test of faith. It’s also a nightmare for collectors who want to keep their sets in mint condition. You have to choose: do you keep the box pristine, or do you get that one unique card that nobody else at the table has?
The foil pack surprises
Then there’s the packaging itself. Have you ever looked at the fine print? Most people ignore the legal jargon on the back of the silver foil packs. Don’t. Sometimes, the "instructions" include recipes for a mediocre sangria or cryptic warnings about the end of days. In the 2014 Holiday Pack, the "Ten Days of Kwanzaa" (or whatever specific year’s gag it was) often included hidden web addresses. These weren't just links to a storefront. They were portals to weird, one-off mini-games or bizarre audio clips.
Digital breadcrumbs and the $5 hole
Cards Against Humanity has always been more of an anarchist performance art collective than a traditional game company. Remember the "Holiday Bullshit" campaigns? They weren't just sending you cards. They were sending pieces of a puzzle.
One year, they literally sold "Nothing" for $5. People bought it. Thousands of people. They got a receipt that confirmed they were receiving absolutely nothing. Another year, they used the money from their Black Friday "sale" (where they increased prices) to dig a massive hole in the ground for no reason.
The Cards Against Humanity easter egg in these stunts is usually buried in the source code of their websites. If you’re the type of person who hits Ctrl+U on a browser, you’ll find comments from the developers. Sometimes it’s a joke about how much they hate CSS. Other times, it’s a hint toward the next expansion theme.
The hidden website layers
Back when they launched the "Science Pack," the promotional site had a hidden input field. If you typed in specific scientific constants—think Planck's constant or the speed of light—the site would change. It wouldn't give you a discount. It would just show you a GIF of a sloth or a weirdly specific fact about Phil Collins. That’s the CAH brand: high effort, zero utility.
Hidden cards in plain sight
Let's talk about the physical cards. Most people think the humor is just in the text. Look closer at the icons in the bottom corner. During specific limited runs, the logo (the stacked black and white squares) would be slightly altered.
In the "Hidden Compartment" pack—which was literally an expansion hidden inside a physical box of "Target" brand procedural items—the cards were themed around conspiracy theories. But the real Cards Against Humanity easter egg was that the cards themselves could be laid out to form a map.
I’ve seen people on Reddit spend weeks trying to overlay these maps onto actual GPS coordinates. Sometimes it leads to a park in Chicago. Sometimes it leads to a dead end. The point isn't always the destination; it’s the fact that you’re looking for a destination in a card game about "Bees?" and "The Ubermensch."
- The 15th Anniversary Box: Check the underside of the plastic tray.
- The Retail Product: Even the barcodes sometimes have hidden messages if you read the numbers as a cipher.
- The "Post-Trump" Pack: Included a literal piece of "pre-divided" land on the border.
The "Secret" 2024 and 2025 Updates
As we’ve moved into the mid-2020s, the easter eggs have gone high-tech. There are rumors of cards with embedded NFC chips that trigger specific playlists on your phone, though these are mostly limited to promotional "influencer" sets. However, for the average player, the most common Cards Against Humanity easter egg now involves the QR codes found on the "About" inserts.
Don't just throw those inserts away. In 2024, one of those codes led to a secret "un-buyable" expansion pack that you could only get if you solved a series of riddles involving the history of the company’s lawsuit against SpaceX.
It’s messy. It’s complicated. It’s exactly what the fans want.
Is it worth finding them?
Honestly, if you're looking for a "power-up" or a way to win the game, you're missing the point. You can't "win" Cards Against Humanity. You just lose a little bit of your soul and gain a lot of laughs. Finding a Cards Against Humanity easter egg is about the thrill of the hunt. It’s about knowing something the rest of the people at your party don't.

When you pull that secret card out of the bottom of the Bigger Blacker Box, the look on your friends' faces is worth the damage to the cardboard. It’s like a secret handshake for the cynical.
How to find your own hidden cards
- Feel the weight. If a box lid feels heavier than it should, there’s likely a card glued between the layers of cardboard.
- Inspect the "void." Take out the plastic or foam inserts. Look at the bottom of the box.
- Read the fine print. Use a magnifying glass on the expansion packs.
- Check the URLs. If a card mentions a specific website, go there. Then look at the source code.
Actionable Steps for the Aspiring Secret-Hunter
If you want to find your first Cards Against Humanity easter egg, start with your storage box. Grab a flashlight. Shine it along the inner seams of the box. Look for any slight bulge in the paper lining. That’s usually where the "hidden" cards live. If you find one, don’t just rip it out—use a thin blade to slice the adhesive.
Next, go to the official CAH website and look at their "Past Promotions" page. Many of the digital easter eggs are still active, even if the physical products are sold out. It’s a great way to see the evolution of their humor.
Finally, join a community like the CAH subreddit. People there have mapped out almost every variation of the hidden cards from the last decade. It’s the fastest way to verify if that weird typo on your "Abe Lincoln" card is a mistake or a clue to a much larger joke.
Stop treating it like a board game and start treating it like a scavenger hunt. The best cards aren't in the deck; they're in the walls of the box.
