Set is proof that a card game does not need hundreds of cards or a sprawling rulebook to earn 35-plus game awards, including a MENSA Select honor.
Designer Marsha Falco created the game in 1974 as a visual tool for tracking genetic traits in a research project, and Set Enterprises published it for retail in 1991.
The entire game fits into a single 81-card deck, one of the smallest total card counts of any widely sold tabletop game still in print.
Here is the real card count, the confirmed dimensions, and an honest answer on sleeve fit, since Set does not use the same card size as most trading card games.
Every one of Set's 81 cards represents a unique combination of four features: number of shapes, shape type, shading, and color, with three possible values for each feature, which is exactly how 3 multiplied by itself four times equals 81.
There are no separate expansion packs or variant card types to track, just the one complete 81-card deck used for every game, which keeps this one of the simplest decks in the hobby to fully sleeve in a single sitting.
Set's cards measure 57 by 89mm, a noticeably narrower width than the 63.5 by 88.9mm standard poker size used by most trading card games and many other board game decks.
That smaller footprint is part of why Set travels so well; the deck and box are genuinely pocket-sized compared to almost anything else in a typical game collection.
EVORETRO does not currently carry a dedicated sleeve cut specifically for Set's narrower 57mm-wide card, so a standard-size sleeve will run slightly loose around the width rather than hugging the card edge to edge.
That is a real tradeoff worth knowing upfront rather than discovering after opening a pack, since a slightly loose sleeve still protects against spills and general handling, just without the snug fit a dedicated Set-sized sleeve would give.
With only 81 cards and a correspondingly small box, Set is one of the easiest real games to toss into a bag for a flight, a car ride, or a weekend trip without taking up meaningful space.
That same compact footprint makes it practical to keep an unsleeved backup deck on hand for travel while a sleeved primary deck stays protected for regular home use.
Because every card gets laid out and picked up constantly during a round, with twelve cards face up at any moment, Set's deck sees a lot of repeated handling relative to its small total size.
Sleeving the full 81-card deck takes only a few minutes given the low card count, making it one of the fastest full-deck sleeving jobs in this entire hobby.
Set belongs to a small category of genuinely pocket-sized tabletop games, closer in footprint to a deck of standard playing cards than to most modern board games with their sprawling boxes and inserts.
That small footprint is a real selling point for collectors who want a strategy-adjacent game without dedicating a shelf slot the way a typical 128-card or 200-card title would require.
For a game that mostly gets played casually at home, a slightly loose standard sleeve still beats leaving the deck completely unprotected, since it blocks spills and general edge wear even without a snug fit.
Collectors who want a tighter fit specifically for Set can look for sleeves marketed at the smaller mini-European card size used by some import games, though EVORETRO does not currently stock that narrower cut.
A deck this size does not need a large storage box, and oversizing storage can actually make 81 loose or sleeved cards harder to keep organized than a tightly sized container would.
A compact option like EVORETRO's Plastic Deck Box, sized closer to the card count, keeps Set's small footprint intact rather than undoing the portability that makes the game appealing in the first place.
Because it takes up so little shelf space and sets up almost instantly, Set tends to stay in regular rotation long after bigger box games get shelved for a while between plays.
That steady use is actually a strong argument for sleeving it despite the sizing mismatch, since frequent handling adds up over time even on a deck this small.
81 cards total, covering every combination of the game's four features.
57 by 89mm, narrower than the standard 63.5 by 88.9mm poker-size card.
No, a standard-size sleeve is the closest available option and will fit slightly loose.
Yes, its small 81-card deck and compact box make it genuinely pocket-friendly.
Give Set's compact deck a protective layer with EVORETRO's Matte Card Sleeves Standard Size, the closest sleeve fit available for this smaller card.
