Two Thumbs Up for color, number and pattern recognition, and for the dexterity (visual and manual) required to play this game. Based on the challenge card drawn, players race to be the first to stack different colored rings on their thumbs. Pacifiers, melting candles, balloons and bowling pins are just some of the cheerful cartoon-like images that display up to seven numbers per card to match, stack, and win. The first player to win five challenge rounds wins the game. With 50 challenge cards, there is plenty of long-term play and educational value and an abundance of fun.
