Uno Rules

Players match cards by colour or number, trying to be first to empty their hand.

Format

2-6 players per game; a league usually plays best-of-a-set-number-of-rounds per fixture.

Scoring
  • Winner of a round scores the total card-point value left in every opponent's hand
  • League table ranks by total points across the season, or by rounds won if playing quick single-round matches
  • Tiebreaker: most rounds won
Key Rules
  • Match the top discard by colour, number, or symbol, or play a wild card
  • Call 'Uno' when down to one card — forgetting means a penalty draw in most rule sets
  • First to empty their hand wins the round

The rules almost everyone gets wrong

Stacking draw cards, where a Draw Two is answered with another Draw Two, is not in the official rules and is played nearly everywhere. Nor is playing a Draw Four whenever you like: officially you may only play it when you hold no card matching the current colour.

Neither house rule is wrong, but they change the game substantially, and stacking in particular can knock a player out of contention in one turn. Decide before the first hand and write it down, because this is the single most argued-about thing in casual Uno.

Scoring a season

Uno's official scoring gives the round winner points equal to the cards left in everyone else's hands, playing to 500. That works well for a league because it rewards going out quickly rather than just going out first.

The alternative, one point per round won, is simpler but far noisier: with six players, a round win is close to a lottery. Point scoring across many rounds separates players much more reliably.

Common questions

What is the penalty for not calling Uno?

Officially, a player caught with one card who has not called Uno draws two cards, but only if another player catches them before the next player takes their turn. Leagues should state how strictly this is policed, since it is often ignored entirely.

How many players work best?

Four to six. With two players many of the action cards lose their meaning, and with eight or more a full circuit of the table takes long enough that the game state changes completely between your turns.

How long does a round take?

Five to fifteen minutes depending on player count and whether you stack. Playing to 500 points across multiple rounds typically fills about an hour, which fits neatly into a games night alongside something longer.
