The technology tree icon

Technologies can be researched using stars. They unlock new abilities, units, and buildings. All tribes, except for Luxidoor and Aquarion, start with a technology that is already researched.

Tech tree HD

The Xin-xi technology tree

Technologies belong to one of three tiers. Tier one (T1) technologies can immediately be researched at the start of the game and initially cost five stars. Tier two and three technologies can be only researched after the T1 or T2 technology of the branch is researched and initially cost six or seven stars, respectively.

The cost to research a technology increases with the number of cities in the tribe's empire. The cost of a technology is calculated as follows:

cost = (tier of technology) × (number of cities) + 4
In other words, for each additional city or village captured, the cost of technologies increases by one, two, or three stars for T1, T2, and T3 technologies, respectively.

The Literacy ability, unlocked with the Philosophy technology, decreases the price of technologies by 20% (rounded up).

To access the technology tree, where new technologies are researched, tap the blue beaker at the bottom of the screen. If you can currently afford a technology, the button will glow blue. If not, it will be black.
