About Expand.io: Claim Territory and Conquer the Arena

Expand.io puts you in a contest to grow your territory, outmaneuver opponents, and become the largest presence on the map. The goal is straightforward: claim new areas, guard your borders, and push across the arena one move at a time. Several scenes show a green textured surface partially covered by large orange pebbled shapes and smaller light-blue tiled shapes, giving the playing field a vivid, patchwork look.

How to Play Expand.io

Move across the map to claim new areas and push back rivals. Protecting your borders while expanding into fresh territory is the core challenge — every direction you move is a decision about where your influence grows next.

Controls

• WASD keys: Move in different directions
