Suroi.io is a free battle royale io game (battle-royale, open-source). Drop in, loot, and outlast a shrinking circle. The 2D versions load in seconds and finish in minutes. It ran when last checked, on 2026-09-16.
The game loads from suroi.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 suroi.io. If you already have progress there, open the game on its own site. How the frames work.
