3-2-1 Countdown is a retro space travel-themed game in which players race to blast off by earning points with the lowest total hand value. Shed your cards onto one of the two discard piles by playing singles or sets, ending your turn by drawing a single card.

The goal is to declare "countdown" and end the round with the lowest total value in your hand.

• If the player who declares "countdown" has the lowest hand, they earn points and bonuses.
• If another player has a lower hand, the declarer earns no points, and other players score instead.

Deciding whether to keep shedding cards on your turn or risk declaring "countdown" is a strategic gamble!
