UNO Stacko is a board game released in 1994 for 2–10 players, 20 minutes per game, and ages 8 and up. It was designed by Jim Keifer and its main mechanics are Dice Rolling and Stacking and Balancing.
Jenga meets Uno. The blocks are colored and numbered, so you have to pull a block that matches either the color or the number of the previously-pulled block. Earlier editions of this game (1994-1996) had a die, the Uno cube, which was used to determine which kind of block had to be moved. In the versions with dice, the die determined either the number or the color of the block to be removed. The Reverse and Draw Two actions were only reflected on the die. In the later non-dice versions (1999-present), the actions were instead represented with symbols on some of the blocks (Reverse, Draw Two, Skip Turn, and Wild).
UNO Stacko supports 2–10 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 UNO Stacko 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 UNO Stacko 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.
UNO Stacko has a complexity rating of 1.1 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.
