Decrypto is a sharp, codebreaking party game where two teams try to decode each other's secret words while protecting their own, designed by Thomas Dagenais-Lespérance and published by Le Scorpion Masqué in 2018.
It went on to win the 2019 UK Games Expo Best Party Game People's Choice Award, and it's stayed a frequent recommendation for groups who enjoy Codenames but want something with a sharper competitive edge.
Each team keeps four secret keyword cards tucked into their own screen, giving coded clues round after round while trying not to give their opponents enough information to crack the code.
That screen is also the reason this game's sleeve question has a genuinely important wrinkle, so here's the real card breakdown before buying anything.
Sleeve-fit database sleeveyourgames.com lists two distinct card types for Decrypto: 48 code cards at 52mm square, and 110 keyword cards at 44mm by 68mm. That's a genuinely different pair of sizes, not a rounding difference between two similar dimensions.
Knowing which card is which matters here more than in most other games in this series, since one of these two sizes has a mechanical constraint that goes beyond simple protection.
The 48 square code cards cover the digit combinations players use to signal their coded clues each round, drawn from a shared pool and discarded after use. With four possible digits and three shown per card, the deck covers every meaningful combination with room for repeat plays across a long session.
These get shuffled, drawn, and discarded constantly throughout a match, which makes them the card type that sees the most repeated handling over a typical game.
The 110 keyword cards, each printed with a single secret word, measure 44mm by 68mm and get tucked directly into numbered pockets on each team's physical screen at the start of the game, staying there for the entire match. That screen pocket is sized for an unsleeved card, not a sleeved one.
Sleeveyourgames notes this directly: the 44mm by 68mm keyword cards need to fit into the screen, and a sleeve added to the card makes that fit noticeably worse. That's a real, practical reason to think twice before sleeving this specific card type.
Most games in this series face a simple closest-fit decision for a single card type, but Decrypto genuinely splits into two different answers depending on which cards you're protecting. The code cards can reasonably be sleeved without affecting gameplay, since they're drawn and played from the hand rather than slotted into a fixed-size screen pocket.
The keyword cards are the opposite case, where sleeving actively works against the card's intended function, which makes this one of the few games in this entire series where the honest recommendation is to leave a card type unsleeved on purpose.
EVORETRO doesn't currently stock a dedicated square sleeve for the 52mm code cards, and the keyword cards shouldn't be sleeved at all given the screen-fit issue, so neither of Decrypto's two card types ends up with a true factory-exact EVORETRO match. That's worth stating plainly rather than forcing a recommendation onto either size.
This is a different kind of honest disclosure than this series usually makes, since the gap on the keyword cards isn't really about dimension at all, it's about a sleeve actively interfering with a physical game component.
For the 48 code cards specifically, EVORETRO's Perfect Fit Sleeves Inner Card Protector, built to hug a card tightly, is a reasonably close approximation compared to a standard-width outer sleeve that would sit loose on a 52mm square card. It isn't a true square cut, but it's a meaningfully tighter result than leaving the cards entirely unprotected.
Since the code cards aren't screen-constrained the way the keyword cards are, this is the one place in the box where sleeving genuinely makes sense without a mechanical downside.
For the keyword cards, the EVORETRO Resealable Team Bags work well as unsleeved storage, keeping the full 110-card pool bagged and organized between sessions without adding any bulk that would interfere with the screen later. It's a container solution, not a per-card sleeve, which is exactly what this particular card type actually needs.
That approach protects the deck from general wear and loss without ever risking the fit problem a sleeve would introduce the next time the screen comes out.
Two: 52mm square code cards and 44mm by 68mm keyword cards.
Not recommended, since a sleeve makes them fit the team screen's pockets noticeably worse.
No, the closest available option is the Perfect Fit Sleeves inner protector.

Sleeve the code cards with EVORETRO's Perfect Fit Sleeves Inner Card Protector, and leave the keyword deck unsleeved for the screen's sake.
