15°C

15°C is an educational cooperative game that beautifully demonstrates the balance of Earth's climate. It teaches players that greenhouse gases are not inherently evil; a certain amount is necessary to keep the planet from freezing. The true challenge lies in active management and finding the perfect balance.

Through simple hand-management mechanics, players play cards to add or remove greenhouse gases and handle radiant energy. Heat cubes are continuously trapped by greenhouse gases on the board. Players must carefully time their actions—like triggering a "Virtuous Cycle of the Ecosystem" to clear heavily saturated Methane or CO2 cards—to release heat back into the atmosphere and cool the planet down.

Starting at 7°C, players must survive the entire deck of cards. You will inevitably heat up the Earth, but you must work together to cool it back down to a perfect 15°C by the end of the game. It is a highly engaging game of timing and teamwork that brings the pressing issue of global warming to the tabletop.
