UNO Stacko blends the classic color and number matching of UNO with a stacking challenge that tests precision and balance. Players take turns placing blocks on the tower, matching them by color, number, or action symbol. As the structure grows taller, maintaining stability becomes increasingly difficult. The game incorporates strategic decision-making similar to UNO while adding a physical dexterity element. Each block features clear graphic symbols alongside colors, ensuring accessibility for players with color vision differences. Designed for 2 to 10 players, UNO Stacko is suitable for tabletop play in various settings. The standard set includes 45 stacking blocks and instructions.
