Play smart. Stay cool.

Don’t change the climate. Change the game. We all face the same events as a result of the climate crisis. Let’s team up and solve them together.

Act now. Debate later.

The planet doesn’t care about our opinions on climate change. So why not clean up our act anyway? It can’t hurt, and it might just help save life as we know it.

How the game works

Green House is a cooperative card game, a climate change simulator, a conversation starter, and an educational journey all rolled into one. It’s designed for 1-8 Players, ages 12 and up. Games take around 20-30 minutes to complete.

Draw an event.

Start each turn by drawing a climate event. These may be scary, but they can inspire us to action.

Take action.

We’ve packed 64 climate solution cards into this game. Use them to eliminate greenhouse gases.

Work together.

You’ll have to team up to clean our skies before running out of money, time, hope, or fresh air.

Win a better future.

If you succeed, you’ll create a path to a clearer, brighter, happier future. One we can all enjoy together.
