Claim land on a map, balance troops against interest, decide when to attack. Hundreds of players per match and games that last an hour. 2020, David Tschimmel.
Territorial.io is a free strategy and territory io game (rts, free-for-all, teams). 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 2026-09-16.
The game loads from territorial.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 territorial.io. If you already have progress there, open the game on its own site. How the frames work.
