"Playing the game definitely helped with the students' abilities and enthusiasm for chemistry."

Shari Hiltbrand, Middle School Science Teacher at the Kincaid School, Houston, TX

“As a 10 year old boy, my first impression to the game valence was "this game looks silly." I thought "what do science ninjas have to do with anything? But then I tried it out and the game was easy to learn, but challenging to play. I even like to play it on my own. I didn't know much about chemistry before this game. Now I know all kinds of new things like halocarbon, carbon dioxide, and metal oxide.”

“This game makes beginning chemistry easier to understand. My son age 10 5th grade is home schooled and I wanted something a little less abstract to help him get a bead on elements and molecules. This game is alot of fun, and we play it as a family.”
