What makes Expanding Land different from other IO games?

Expanding Land stands out with: (1) Pure C server engine achieving ~5ms tick time — 8x faster than Node.js servers; (2) 720 real players, zero bots — every cell is a real human; (3) Resizable map that automatically grows or shrinks based on active players; (4) Encrypted WSS/TLS connections for security; (5) Anti-cheat coordinate scrambling; (6) Session stats showing time alive, highest mass, food eaten, and players eaten.

Does Expanding Land have an anti-teaming system?

Yes. Expanding Land uses an advanced discrete event-based anti-teaming system. Each action (splitting, ejecting mass, virus pops) creates an independent penalty event with its own lifespan. Old events expire naturally without being extended by new ones. When the total penalty score exceeds the threshold, decay rate increases proportionally, discouraging teaming while keeping solo play fair.

What features does Expanding Land have?

Key features include: 720 real players per server, resizable dynamic map, 200+ spectator slots, full leaderboard, custom skins from Legend Mod, ghost cells on death, in-game chat, spectator mode with free-roam, session stats (time alive, highest mass, food eaten, players eaten), encrypted connections, anti-cheat protection, and compatibility with Legend Mod and Delta extensions.

Is Expanding Land compatible with mods?

Yes! Expanding Land is fully compatible with OGario-based mods including Legend Mod and Delta. Players can use custom skins, themes, and extended features through these browser extensions. Visit legendmod.ml or deltio.pages.dev to get the mods.
