HISS! 2026

HISS! is a fast-paced, interactive hand-shedding card game for 4–8 players, packed with sneaky cats and chaotic powers.

On your turn, play a card that matches the current color or number, play a combination of cards with the same number, or unleash a Cat Card with a rule-breaking ability. Force opponents to draw, reverse the direction of play, swap hands, redirect attacks, and disrupt whoever is closest to winning.

But in HISS!, the action does not always wait for your turn. Three signature twists keep every player involved:

POUNCE! — When another player plays a single Number Card, interrupt the turn order by immediately playing a card with the exact same color and number. React quickly, and you can jump into the action before the next player takes their turn.

Parasites — Each Parasite attached to you forces you to draw an extra card at the beginning of your turn—and you cannot win while you have one. Cure it or pass it to another player before it is too late.

HISS! — Whenever your own play leaves you with just one card, you must call “HISS!” before another player catches you. Forget, and you may face the consequences.

Just when everything seems under control, a House Party Card can throw the entire table into chaos by redistributing everyone’s hands, passing them around the table, or forcing every player to draw.

Be the first player to empty your hand—but choose your final move carefully. Only a Number Card can be played to win, and in HISS!, victory can disappear in a single turn.
