BrainBox Nature is a fast and fun memory game that does not require any pens, pencils, paper or even a playing board. Simply look at a card for 10 seconds and answer a question based on the roll of a die. If you answer correctly the card is kept, if the answer is wrong the card is returned to the box. The winner of the game is the person who holds most of the cards. BrainBox Nature comes with 54 game cards, rules card, timer, 8-sided die and a handy magnetic cube storage box.
