Stack'em is a fabulous game requiring lightening reflexes & a steady nerve! Roll the three dice together. Grab & stack the cups with one hand in the order the colours appear on the dice (largest to smallest), aiming to be the first to hit the bullseye! Faced with 36 cups, this is easier said than done! It's unbelievably addictive! A sneaky left/right hand challenge adds an extra devilish dimension for those who have mastered the basic game. Absolutely brilliant!
