Covalence is a cooperative game—everyone is on the same side. Because Covalence is a co-op game and encourages team-building, it's ideal for players of all ages. Young and old unite in an attempt to build their secret molecules. 

One player has knowledge of the secret molecules and gives clue cards to the other players. Use element tiles (carbon, nitrogen, hydrogen, and oxygen) to build your molecules. Build all secret molecules before the guess tokens and clue cards run out and everyone wins!

This game can be played with up to three builders (4 players total). You can also include more people through building teams (up to 7 players total). 

Those with little knowledge of chemistry will pick up the rules quickly. It takes minutes to explain, so play can begin right away! There are also four different levels of difficulty. Start with Easy, then work your way up. Each level offers more complicated molecules than the last.

The science concepts covered include: types of molecular bonds, isomers, electrons, covalence


Covalence is for ages 8 and up. 3-7 players at a time can learn chemistry basics in an entertaining way. Four difficulty levels make games last from 15-45 minutes.
