About Colonist.io
Settlers of Catan in the browser, with ranked matches and expansions. Free to play, no download. 2018.
Colonist.io is a free strategy and territory io game (board-game, turn-based). Claim land, hold it, take someone else's. From the twitchy grid-claiming of Splix to hour-long map wars in Territorial. It ran when last checked, on 2026-10-30.
The game loads from colonist.io in a frame. Its own terms, privacy policy, ads and accounts apply inside it, and a save made here is separate from one on colonist.io. If you already have progress there, open the game on its own site. How the frames work.
