Thumbs Up! is what you'll say if you're faster than the other players and can arrange your rings first. To start play, each player take eight rings — two each of red, blue, green and yellow — and places them on the table. Each round states with one player revealing a challenge card that shows a colored image, with numbers on the various colored items. Players then race to stack some of their rings on one thumb in the order shown on the challenge card. The first player to do so claims the card, and the first player to collect five cards wins! Thumbs Up! includes variants that have you start each round with the rings on your fingers or in a pile in the center of the table.
