Tipping point is like SimCity but with cards. Players build cities while trying to survive extreme weather disasters that become more and more frequent as carbon dioxide accumulates in the air. It's a family-friendly game, a perfect fit for casual and strategic gamers. It also makes a great choice for teachers looking for a visual way of introducing their students to climate change.

The objective of the game is to grow, sustain and protect a large population. Players take turns taking new citizen cards and purchasing new development cards to add to their city.

Each citizen has their own special ability, such as the construction worker who can help you repair your city, the educator who can teach your workers to use advanced technologies, and the soldier who can help protect your city from outside attack.

One of the best parts of Tipping Point is that players may use their imaginations to build the type of city they want. There are dozens of different development cards to choose from, such as oil wells which earn more money, hospitals which protect citizens from extreme weather, or power plants which are needed to power buildings. But this growth and development comes at a cost: the release of greenhouse gases, like carbon dioxide (CO2).

The end of the game is triggered when a player reaches a population of at least 10 citizens. Since Tipping Point also has a semi-cooperative mode, it is possible (but very challenging) for all players to win.
