Think game, think science, think fun! In ROY G. BIV players will compete in a family style, head to head set collection game, which involves a science themed learning experience. Be the first player to collect and play a colorful array of seven cards that represent a rainbow and WIN! Players will draw and play cards which represent the 7 colored components of a rainbow from a common draw pile, in a race to be the first to make their rainbow appear! Successful creation of a rainbow is accomplished by playing a card of each color, in order (Red, Orange, Yellow, Green, Blue, Indigo and Violet), to form a set of cards deemed a rainbow. But beware, opponents can rain on your parade, and influence how long it will take your rainbow to appear!
