Cards Against Humanity is a weird company. They’ve spent millions of dollars to dig a hole in the middle of nowhere for no reason, sold literal boxes of poop to customers, and once bought a plot of land on the US-Mexico border just to make a legal headache for a wall project. It's chaos. So, when people start hunting for Cards Against Humanity easter eggs, they aren't just looking for clever jokes or hidden text. They’re looking for things that might be physically buried inside the products they bought.
Most board games come with a rulebook and some pieces. This game comes with a sense of paranoia. If you’ve ever felt the lid of your Bigger Blacker Box and thought, "Wait, is there something in here?" you aren't crazy. You're just part of the target audience.
The Bigger Blacker Box and the Hidden Card Ritual
The most famous of all Cards Against Humanity easter eggs is tucked away inside the Bigger Blacker Box. This is the massive storage case designed to hold the thousands of expansion cards the company churns out. For years, rumors swirled on Reddit and BoardGameGeek that the box held a secret. It turns out the rumors were underselling it.
If you take a box cutter—carefully, obviously—to the bottom lining of the original Bigger Blacker Box, there is a card hidden inside the literal cardboard. It’s usually a unique white card that says "The Biggest, Blackest Dick."
It’s a literal physical secret.
But then they updated the box. The "Box" version released around 2017 upped the ante. In that version, if you tear into the lid, you find a different card. Sometimes it's a "Biggest Blackest Dick," but other versions have hidden foil cards or even more obscure jokes printed directly onto the inner corrugated cardboard.
Why do they do this? Because Max Temkin and the rest of the CAH crew have always viewed the physical packaging as part of the game. They want you to destroy the thing you paid for to find a joke. It’s high-effort trolling.
Honestly, the commitment to the bit is what makes these Cards Against Humanity easter eggs different from a standard video game secret. You can't just press a button. You have to commit property damage.

Hidden Web Secrets and the 99-Cent Store
The digital side of the game is just as messy. During their Black Friday "deals," the company often hides links in the source code of their website. One year, they sold "nothing" for $5. Over 11,000 people bought it. There was no secret card or hidden gift. They just sent an email saying thanks for the five bucks.
But other times, the Cards Against Humanity easter eggs are more lucrative. During the "Ten Days or Whatever of Kinda-Free Stuff," hidden puzzles led users to secret checkout pages where they could claim absurd items for pennies.
We saw this again with the "99-Cent Store" stunt. If you scrolled to the very bottom of the page and clicked on specific, unassuming pixels, you’d be redirected to a page about the company’s "Pikachu" card—which doesn't exist in the way you think it does. It was actually a legal disclaimer about how they weren't allowed to make a Pikachu card.
The Mystery of the Slap Stickers
Not every secret is a card. Sometimes it's just a weird piece of paper. In certain expansion packs, particularly the older "Holiday Packs," users reported finding tiny, microscopic text on the flaps of the boxes.
If you look at the "Science Pack," there’s a series of numbers that, when plugged into a coordinate system, point to a specific spot in Hawaii. Is there something buried there? Maybe. People have gone looking. Some found small caches; others found nothing but dirt and regret.
Then there are the "Slap Stickers." These were included in various mystery bundles. If you peel the back of the sticker, there’s often a code. These codes used to link back to a hidden section of the CAH website that hosted a bizarre, lo-fi terminal game. Completing the game didn't win you a prize—it just gave you a "Certificate of Achievement" that you could print out. It’s the ultimate anticlimax, which is exactly the brand’s humor.
The Hidden Meanings in the "Safe for Work" Pack
People buy the "Family Edition" or "Safe for Work" packs thinking they’re getting a neutered version of the game. They are. But the Cards Against Humanity easter eggs in these packs are arguably more clever because they have to work within constraints.
In the Family Edition, if you arrange specific cards in a certain order based on the serial numbers on the bottom left corner, they form a hidden message about a "fart" joke that spans across six cards. It’s juvenile. It’s unnecessary. It’s exactly what you expect.
The Science Behind the Secret Cards
It isn't just about hiding things in boxes. The way the cards are printed actually allows for some "meta" secrets.
- The Foil Variations: Some packs have a 1-in-1000 chance of containing a card where the text is slightly altered. Not a typo, but a completely different punchline.
- The Procedural Generation: In the "Your Dumb Joke" packs, the cards are printed using a system that ensures almost no two packs are identical. The "easter egg" here is that your pack might be the only one in the world with a specific, procedurally generated insult.
The Most Expensive Easter Egg: The Land Plot
Back in 2017, the company launched "Cards Against Humanity Saves America." They bought a plot of vacant land on the border. If you were one of the people who paid $15 for the promotion, you received a map.
The map itself contained a series of Cards Against Humanity easter eggs. There were hidden illustrations of the CAH writers' pets, and a set of GPS coordinates. These coordinates led to a specific spot on the property where a "Time Capsule" was supposedly buried.
The "Time Capsule" didn't contain gold. It contained more cards. Specifically, cards that were too weird or "too soon" for the general public. These are some of the rarest physical items in the tabletop gaming world. People sell them on eBay for hundreds of dollars, even though they’re just pieces of cardstock with jokes about 2017 politics.
How to Find Your Own Secrets
If you’re sitting there with a stack of expansion packs, you might be wondering if you’ve missed something. You probably have. The company loves to hide things in plain sight.
Start by looking at the copyright lines. On some packs, the copyright year is wrong on purpose, or the "All Rights Reserved" text is replaced with a recipe for a mediocre dip.
Check the "Crabs Adjust Humidity" or other third-party packs too. While not "official" CAH products, these creators often pay homage to the original by hiding their own Cards Against Humanity easter eggs. In one third-party pack, the box itself is held together by a specific type of glue that, when heated with a hairdryer, reveals a hidden URL on the inner flap. That is an insane level of dedication for a parody product.
Why the "Poop" Was the Ultimate Secret
Remember when they sold "Bullshit"? It was a box for $6. It contained literal, sterilized bull feces.
The "easter egg" here was the packaging. Inside the box—under the poop—was a small, foil-wrapped "Secret Poop Card." Most people were so disgusted by the contents (or so committed to keeping it "mint in box") that they never found the card.
The card itself was a silver-foiled white card that simply said "Literal Piece of Shit."
It’s the perfect metaphor for the game’s philosophy. The real secret isn't some grand treasure. It’s just another joke, usually at your expense, hidden behind a layer of something gross or destructive.
Actionable Tips for the Secret Hunter
If you're serious about finding every hidden detail, you need a toolkit.
- Get a Blacklight: Some of the newer promotional cards have UV-reactive ink. This was used extensively in the "Post-Trump" packs.
- Check the Dividers: In the larger storage boxes, the foam spacers and plastic dividers are often hollow or double-walled.
- Don't Be Afraid to Destroy: If you have an old Bigger Blacker Box that's falling apart, peel back the layers. The "Biggest Blackest Dick" card is almost always there, waiting in the literal guts of the cardboard.
- Inspect the Serial Numbers: Every CAH card has a tiny alphanumeric code. While most are just batch numbers, some packs (like the Pride Pack) used these codes as part of a puzzle that led to a charitable donation page.
The best way to stay updated on Cards Against Humanity easter eggs is to watch their seasonal "sale" sites. They don't announce these secrets. They just leave them there for the most obsessive fans to find. If you find a link that looks like a typo, click it. If a box feels a little too heavy, open it.
Just remember: once you cut open your box to find a hidden card, you can't exactly un-cut it. The secret is yours, but the box is ruined. That’s the trade-off. It's a game about making bad choices, after all.
To verify if your specific edition has a secret, look at the bottom of the box for the "v" number (e.g., v2.0, v2.4). The community-run CAH Wiki maintains a living database of which versions contain which physical hidden cards. If you have v1.0 of the Bigger Blacker Box, the card is in the bottom. If you have the "Box" version, check the lid. Always check the lid.
