Zero Down is a board game released in 1998 for 2–5 players, 20 minutes per game, and ages 8 and up. It was designed by Reiner Knizia and its main mechanics are Set Collection and Open Drafting.
How low can you go? In Zero, you want to score as few points as possible, but to do that you need to collect the right cards in hand. The deck consists of 56 cards, with cards numbered 1-8 in seven colors. Each player starts with nine cards in hand, and five, seven or nine cards start face-up on the table depending on the number of players. On a turn, you either knock on the table to pass or you swap one card in hand for one card on the table. After the second knock, whether from the same player or a different one, all players other than the second knocker have one final chance to swap, after which they reveal and score their hands. If you have five or more cards of the same color or number in hand, then those cards score 0 points. For each other number you have, no matter how many copies, you score points equal to that card's value. Thus, having one to four 7s in hand is worth 7 points. If, however, you manage to collect both five cards of a color and five cards of a number in hand (with one card fitting in both sets), then you can declare "Zero!" and end the round immediately, with everyone else scoring points as usual. After a number of rounds equal to the number of players, whoever has the lowest score wins!
Zero Down supports 2–5 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it. Some setups, rules and scoring details may still vary by player count, so check your edition’s rulebook for the exact configuration.
The listed playing time for Zero Down is 20 minutes. This is the publisher’s estimate for a full game. The actual duration depends on the group, the player count and familiarity with the rules: first sessions usually run longer, while experienced groups often finish faster. Setup and teaching time are not included in this estimate.
The catalogue lists Zero Down for ages 8 and up. This is the publisher’s recommendation and reflects reading demands, rule complexity and small components rather than theme alone. Younger players can often join with help from an adult, so check the age guidance on your edition and consider your group’s experience with board games.
Zero Down has a complexity rating of 1.2 out of 5 from BoardGameGeek players, which makes it a light game. The rating reflects how much rules knowledge, planning and decision-making a typical game demands. Expect a longer first teach for heavier games, and use a preparation guide before game night.
