Kems is a team card game that relies on non-verbal communication between partners. Two pairs compete around a table, each trying to gather four identical cards while decoding the intentions of the opposing team. Games rarely last more than twenty minutes, but the tension they generate far exceeds what a simple game of 52 cards would suggest.
Secret signs in kems: the mechanics that rule sheets gloss over
Most guides dedicated to kems describe the phase of choosing the secret sign in one line. Yet, this is where the gap between a chaotic game and a controlled game is played out.

Before the start of the round, each team isolates itself to agree on a discreet signal. This sign will serve to alert their partner that they hold four cards of the same value. The repertoire is vast: winking, resting an elbow on the table, scratching an ear, inserting a specific word into an innocuous sentence.
A common trap is choosing a sign that is too visible. A large gesture (rolling eyes, crossing arms) can be spotted within seconds by the opposing team. Conversely, a sign that is too subtle may go unnoticed by your own partner. The best sign is one that your teammate recognizes in less than three seconds without the opponents catching on.

Some experienced players change their sign for each round to prevent the opposing team from memorizing their habits. This rotation complicates the opponents’ reading but requires solid complicity between partners. Mastering the rules of the kems card game starts with this silent preparation.
Gameplay of a kems round: exchanges and card circulation
The dealer distributes four cards to each player and then turns over four cards in the center of the table. These four cards form the common display.
All players act simultaneously: each can exchange one card from their hand with a card from the display. There are no turns. Speed of decision takes precedence over long reflection. When no one wishes to exchange anymore, the dealer removes the four central cards and turns over four new ones from the deck.
This cycle repeats until a player gathers four cards of the same value (four kings, four 7s, four jacks). At this point, they send the agreed sign to their partner.
Announcing kems and counter-kems
The partner who spots the sign must announce “Kems!” loudly. If the announcement is correct (the teammate indeed has four identical cards), the team scores a point.
The opposing team can intervene before this announcement by shouting “Counter-kems!” if they suspect that an opponent holds a set. A successful counter-kems causes the targeted team to lose a point. Conversely, an incorrect counter-kems penalizes the team that called it.
This counter-kems mechanism transforms the game. Observing your opponents becomes as rewarding as building your own hand. Every gesture, every glance, every hesitation can betray.
Point system and victory conditions in kems
The game is usually played over several rounds. The objective is to reach a predetermined number of points set by the players (often three or five). Here’s how points are accumulated or lost:
- Correctly announced kems by the partner: the team gains one point.
- Correct counter-kems (the opponent indeed had a set): the opposing team loses one point.
- Incorrect counter-kems: the team that shouted loses a point.
- Incorrectly announced kems (the teammate does not have four identical cards): the team loses a point.
This punitive scoring makes every announcement risky. It’s better to let a dubious sign pass than to incorrectly shout kems. Games often shift due to a reading error rather than a brilliant move.
Variants and adaptations of kems in a competitive context
The kems as played in family settings allows for a lot of interpretation. Activity leaders in leisure centers and summer camps have formalized adjustments to frame the games when the stakes rise.
Timer between exchanges
The most common variant imposes a time limit between two rotations of the display. An hourglass or a phone timer replaces the tacit consensus. This constraint prevents players from stalling the game by systematically refusing to exchange. It speeds up the pace and encourages mistakes, making counter-kems more frequent.
Standardized signs for counter-kems
In certain competitive contexts, teams adopt a unique gesture known to all (for example, tapping the table with two fingers) to signal a counter-kems. This standardization reduces conflicts of interpretation regarding the exact moment when the counter-kems was announced in relation to the kems.
Kems with more than four players: what the classic rules do not foresee
Kems is traditionally played with four players (two teams of two). With six players, three teams of two are formed. The dynamic changes radically: monitoring two opposing teams simultaneously divides attention and multiplies the opportunities for counter-kems.
With more than six players, the game loses clarity. The central display is solicited by too many hands, and the signs become impossible to follow. Four players remain the format that offers the best balance between observation and action.
- With four players: standard configuration, only one opposing team to monitor.
- With six players: three teams, divided attention, shorter rounds.
- With more than six: not recommended, the game loses its characteristic tension.
Kems draws its strength from a simple paradox: the rules can be summarized in a few sentences, but the game is won on micro-details that only repeated practice allows one to perceive. The choice of sign, the speed of exchange, the reading of opponents, each element weighs as much as the luck of drawing the right cards.
