Covalence: The Card Game For Aspiring Chemists
In Covalence, players work together to accurately build a number of secret organic molecules. One player takes on the role of the “Knower” who has knowledge of the Secret Molecules, while all other players, “Builders”, must deduce what these secret molecules are, based upon clues given to them by the Knower. All Builders must cooperatively utilize a limited number of clues available in order construct their molecules before the clues run out!
Covalence: A Molecule Building Game is the sibling chemistry game to Ion: A Compound Building Game, which was published earlier this year. While Ion was themed around how ions combine to form ionic compounds, Covalence covers another fundamental type of bonding more common in organic chemistry, Covalent Bonding – more specifically, how the elements carbon, nitrogen, oxygen and hydrogen combine to form organic molecules.
- “This game is a lot of fun. A LOT of fun. I think you have a lot of good things here. …We played three games and we want to play more” – Johnathan Grothe from Game Krackers
One player takes on the role of the “Knower”, who has access to the Secret Molecules while all other players are the “Builders”, who must try to identify the structure of the Secret Molecules through a series of Clue cards given to them by the Knower.
After setting up the Clue cards in front of her, the Knower will randomly designate 2 Secret Molecule cards for each Builder (3 Secret Molecules if there is only one Builder). Each Builder then takes a set of Element Tiles that bear a variety of elements and bonding patterns.
The Knower must study the Secret Molecules designated to each Builder and then give the Builders Clue cards that relate to their specific Molecule!
Each Builder must interpret these Clues as they arrange and rearrange their individual Element Tiles, attempting to deduce the structure of their Secret Molecule.
Builders may request new Clues from the Knower as the game progresses with their limited supply of Clue Tokens.
When the Builders think that the molecular structures they have built match their Secret Molecules, they submit their structure to the Knower with a Guess Token.
If the Builders submit their molecular structures and are wrong, they have exhausted precious resources and are that much closer to losing the game.
If the Builders submit their molecular structures and are correct, they receive more Clue Tokens as a reward and may begin building their next Secret Molecule! If each Builder is able to correctly build both of heir Secret Molecules, everyone wins!
