From the Publisher's web site: Reaction, The Game of Molecules, is a card game that lets you flex your intellectual muscle. Science geeks and regular folk alike will enjoy Reaction's fast pace and competitive spirit, along with the high-quality components. To win, be the first to build the most molecules from the element cards you hold in your hand, and score the most points. It's that simple! Players take turns drawing cards until they can create molecules from the element cards in hand. When a player can build a molecule, they lay it out in front of them on the table. Opponents can add onto the molecule to turn it into a different molecule, or they can destroy it with a Bunsen Burner card. The object of the game is to be the first player to run out of cards and also score the highest number of points from the molecules they created. What's Included: Reaction includes the following high-quality components: -- 100 unique clear plastic playing cards -- A dry erase marker to "multiply" elements when creating complex molecules -- Game Instructions -- Helpful chart of common Molecules to make the game easy to play for everyone -- High-quality outer box to store all items within For two or more players, ages 8 and up. Created, designed and marketed in USA. Printed in China.
