Valence Plus: Advanced Chemistry + Simple Rules + Ninjas

More chemistry! More molecules! More ninjas!
Combine elements from the Periodic Table - recast as science ninjas - into an elite squad to build molecules and win points! Rely on stable compounds to cement your lead, or assemble a team of deadly acids to react with your opponent's vulnerable bases - reducing then to worthless salt and water!

Building on the hit original, Valence Plus introduces new elements, new ninjas, and more that double the molecules and reactions to thrill players into learning chemistry!
