Why try Xterium

Six reasons OGame veterans switch to Xterium and stay.

Alliance wars as core

Alliance wars — not an add-on but the central mechanic. Coordination, diplomacy, team victories.

Full mobile client

Native iOS and Android apps — not a stripped wrapper. All gameplay functions, push notifications, browser sync.

Three universes on one account

War of Alliances, Classic, Reborn — different play styles. One login, switch from menu. Cosmetics and premium — shared.

Transparent economy

All battle / speed / cost formulas — open in the knowledge base. No hidden modifiers, everything calculates.

Active community

Forum, Discord, Telegram, VK. Regular alliance tournaments, daily war discussions, veteran help for newcomers.

No pay-to-win

Premium is convenience (queues, filters, stats), not power. All strategies and victories achievable for free.

Frequently asked questions by OGame players

How is Xterium different from OGame?

Three key differences: (1) alliance wars — core mechanic, not an add-on; (2) full native mobile apps for iOS and Android with browser auto-sync; (3) three separate universes with different balance — you can play in the one that fits your style.

Can I play if I haven't played OGame for a long time?

Yes. The logic of most mechanics is familiar — resources, mines, fleet, research. Modern UI and onboarding will refresh the basics fast. The first-day guide covers 90% of newcomer questions.

Is Xterium paid?

No. Registration and all three universes are free. Premium account is optional — gives convenience (queues, filters, stats), but no combat advantage. No pay-to-win.

Can I play from phone?

Yes. There are native apps for Android (7.0+) and iOS (13+). Progress syncs with the browser version automatically. Alliance chat works with push notifications.

Where do players discuss the game and read updates?

On the Xterium forum — updates, patch notes, war discussions, alliance recruiting. Also Discord and Telegram for fast comms.

Which universe should an ex-OGame player pick?

If you want modern pacing and an active community — War of Alliances (recommended). If you prefer fast classic play — Classic. If you want a seasonal fresh start — Reborn.
