The UNO Stacko game combines the skill of stacking with the fun of UNO. Choose a block that matches the color, number or symbol of the last one played, place it on the top row and try not to be the one who makes the tower fall! The game gets harder as the stack gets higher. There are even classic UNO action blocks like Reverse or Draw 2 that make players take two turns in a row. With 45 colorful blocks, there's plenty of stacking fun for everyone in the family. For 2 to 10 players, ages 7 years old and up.
