Everything you need

Built for people who actually play

Opponents

Five AI tiers, from first game to brutal

Easy through Insane, including a neural opponent trained over sixty experiments to play at an expert level. Pick a fight you can actually lose.

Anywhere

Play with no connection at all

Every AI tier runs on-device. On a plane, on the underground, in a dead zone — the game does not care.

Boards

20+ maps, including fog of war

Beyond the classic board: the USA map, Big Board, and Black Forest, where you cannot see what your opponents are building until it is too late.

Expansions

Seafarers and Cities & Knights, included

Ships, islands and gold hexes. Barbarians, commodities and city improvements. Both expansions are part of the free game, not separate purchases.

Competition

ELO ranked matchmaking

Play rated games against people near your level and watch the number move. Win rate, history and rank all tracked.

Everywhere

One account, every screen

Start in the browser, finish on your phone. Progress, stats and saved games follow you across devices.
