Build a civilization that mitigates global temperature rise by growing Forests, building Wind Farms and Connecting Cities via high speed rail. Manage natural disasters that will occur more frequently and become more disastrous as temperatures inevitably rise.

To win, keep temperature rise below two degrees!

Department Heads

Assign someone to be the head of each department (players may be the head of multiple departments if you are playing with three or fewer people). Give each department head their clipboard.

The Department of Forestry will record the number of Forests in your civilization. Growing and preserving Forests will help you slow the rise in global temperatures.

Forest - any group of tree grove tiles that span three or more contiguous tiles.

Giant Forest - any forest that spans five or more tiles.

Forest Examples

The Department of Energy will record the number of Wind Farms in your civilization. Building and maintaining Wind Farms will help you slow the rise in global temperatures.

Wind Farm - any group of contiguous tiles that have three or more wind turbines on them.

Giant Wind Farm - any group of contiguous tiles that have four or more wind turbines on them.

Wind Farm Examples

The Department of Transportation will record the number of Connected Cities in your civilization. Connecting your cities via high speed rail will slow the rise in global temperatures.

Connected City - any city connected to at least one other city via high speed rail.

Main Line - any group of connected cities consisting of six of more cities that are all connected to each other.

NOTE: Cities are connected to all the other cities that each other city is connected to. 

Connected Cities Examples

The Department of Science will use their clipboard to record the rise in global tempertures. This could be due to a crisis or a New City.

New City - any time a city tile is added to your civilization so that its city sides do not touch any existing city tiles.

New City Examples


Place the five starting tiles as shown here 

(the back side is dark gray).

Shuffle the remaining 40 world tiles and stack them face down in two separate piles. Flip the top tile of each pile face up.

Shuffle all crisis cards and stack them face down in one pile. Flip the top card of the deck face up.

 Randomly assign someone to be the first Crisis Manager.

How to Play

Two Degrees is played over the course of ten rounds. Each round is broken down into two phases: 

Build Phase - Players take turns placing world tiles. The Build Phase ends after four tiles are placed.

Crisis Mode - The Crisis Manager draws a number of Crisis Cards as dictated by a report from the Department of Science. They organize the response and make all final decisions around how to deal with the crisis or crises.


Draw a World Tile

Starting with the Crisis Manager, players take turns drawing a tile and placing it somewhere in your civilization. 

Players may draw from either stack of world tiles.

After a player draws a tile, flip the next tile face up. Players may do this before they place the tile they just drew.

Other players may offer suggestions, but the final decision of where to place the tile is made by the player who drew the tile.

Place a World Tile

New tiles must be played beside at least one existing tile that shares a common side. Any other side of the new tile that touches the side of an existing tile must also match.



End Build Phase

Once four world tiles are placed, move to Crisis Mode.


Draw Crisis Cards

The Crisis Manager must receive a report from the Department of Science. This will be a color (B=Blue, G=Green, Y=Yellow, R=Red. The Crisis Manager must then draw a number of Crisis Cards corresponding to that color.

For each card the Crisis Manager must draw, take the top card off the deck and flip the next card face up. They must choose either the card in their hand or the card on the deck. Whichever they choose is considered the card they have drawn. Discard this card after the crisis is managed. The other card will stay on the top of the deck, face up.

Manage Crises

Crisises must be managed in the order they were drawn, starting with the first card drawn.

The first part of each crisis will require the Crisis Manager to receive a report from a certain department. That report should be given as a color (B=Blue, G=Green, Y=Yellow, R=Red).

The second part of each crisis will require some sort of action be taken. You will either need to record an increase in global temperatures, or destroy tiles of a certain type.

Destroy World Tiles

To destroy a tile, flip the tile face down. Do not remove it from the playing area. 

Destroyed tiles may be built on top of and act as if they are a blank space when placing new tiles.

When destroying tiles of a certain type, each tile will only count as one. For example, a tile with three wind turbines on it will still only count as one wind turbine tile.

If a crisis card requires you to destroy more tiles of a certain type than exists in your civilization, destroy all remaining tiles of that type. If you had zero tiles of that type, you would destroy no tiles.

There is no rule against destroying starting tiles. Starting tiles may be destroyed like any other tile.

Record an Increase in Global Temperatures

First, receive a report from whichever department the Crisis Card tells you. Global temperatures will increase based on the color of that report.

Then, record the increase in temperatures on the clipboard for the Department of Science.


The game ends after ten rounds, this includes managing all the crises for the final round.

If you kept temperature rise under 2.0 degrees, you win! Calculate your Final Temperature using the "End of Game" calculation guides found on each department head's clipboard. Your Final Temperature is the amount of temperature rise that scientist predict your civilization will incur over the next 50 years.

NOTE: Earlier versions of the game use an End of Game Point System. Here is the scoring guide and reviews for the point system.

Final Temperature:

   0.0 - Congratulations! You solved climate change!

   Blue - Great job! Over the next 50 years, your civilization will bounce back pretty close to previous levels of temperature rise.

   Green - Good. You have prevented the more destructive parts of climate change, but keep working!

   Yellow - Not bad. There are definitely worse positions you could be in. Try to build on the successes you can celebrate.

   Red - You avoided complete failure, so let's focus on that.
