Mattel UNO Stacko Color & Number Matching Stacking Block Game

UNO Stacko takes the color-and-number logic of UNO and turns it into a stacking game that gets shakier with every turn. Players pull blocks from the tower based on color, number, or symbol matches, then place each one on top, all while trying not to be the one who sends the whole thing crashing down. It’s a mix of dexterity and strategy that works for game nights or parties, with 2 to 10 players able to join the tension. Every pull is a small gamble, and the tower doesn’t forgive bad choices.

• Fun for 2 to 10 players, so it scales from a quick two-player match to a full party crowd
• Gameplay combines the skills of stacking with UNO strategy, matching blocks by color, number, or symbol
• Includes 45 colorful stacking blocks and a tray, plus easy-to-follow instructions
• Suitable for ages 7 years and up
• Tense, hold-your-breath moments as the tower gets taller and wobblier with each turn
