Compounded: Geiger Expansion, the first full expansion for the chemistry board game Compounded, gives experienced scientists even more to consider in the lab with the introduction of radioactive elements and compounds. As productivity in the lab increases, so does the chance for radioactivity levels to rise. Scientists have to keep a close eye on the geiger counter or else risk the lab becoming too radioactive in which to work.

The Geiger Expansion introduces a new, interactive paradigm to the base game of Compounded as players now sometimes have to work together to eliminate or reduce the threat of radioactivity. Of course, those players with a propensity for causing chaos have even more methods at their disposal, ensuring that each game is exciting and dynamic.

Note: This is not a complete game and requires the base game to play.

Players: 2 - 5 | Playing Time: 60 minutes | Ages: 13 +
