Science is one of the major resources in Civilization.

It is used to unlock new technologies, which give your people new abilities and units.

The more science you produce, the faster those technologies unlock.

Initially, science is generated by your palace.

You can also get science from certain resources, natural wonders, and the Campus District.

Eurekas are boosts to specific technologies, and you can earn them through different things you do in the game.

You don't need a Eureka to complete a technology, but they can speed your scientific progress.

For example, settling a city on a coast automatically completes half of the sailing technology, which helps you improve sea resources.

Discovering another Civilization boosts Writing, which allows you to build the science-producing campus district.

The Campus District is the best way to generate science.

Build Campuses next to Mountains and Jungles to get the highest adjacency bonuses.

Libraries, Universities and Research Labs on your Campuses will further increase their science output, and allow you to assign your population to this tile.

Great Scientists are legendary people your civilization earns.

You can accumulate Great Scientist points each turn, through your campuses and social policies.

You will earn a Great Scientist after enough great scientist points are obtained, or you can patronize one with gold or faith.

Each Great Scientist has a unique and powerful effect.

Wonders can also help with science.

The Great Library boosts all Ancient and Classical Technologies, and Oxford University gives 2 random free technologies.

Certain policies and religious beliefs can help as well.

To Win a Science Victory, you'll need to be the first Civilization to establish a colony on Mars.

First, Research Rocketry.

This will allow you to build a Spaceport district and launch a satellite.

After that, researching Satellites will allow you to land a human on the moon.

The final step requires researching Robotics, Nuclear Fusion and Nanotechnology.

Sending a Mars Habitaion Module, Reactor, and Hydroponics component will complete the Mars Project and a Science Victory.

Be aware, these projects require tons of production, so try to build spaceports in cites with Industrial Zones.

Or you can always get help from a Great Scientist.

Will your civilization reach for the stars?
