One map, countless strategies
Each world lasts one season. Everyone starts from the same point; timing, diplomacy and patience decide the winner.
Fight
Seven tribes, hundreds of tactics
Train infantry, cavalry, scouts and siege engines. Raid, scout, tear down walls, attack in waves or reinforce your allies. Your hero returns from adventures with loot.
Unite
Nobody wins alone
Found an alliance, set ranks and permissions and run your diplomacy. Contribute to shared bonuses, see the attacks coming at your members and defend together.
Victory
Artefacts and the Wonder
Mid-season, powerful artefacts appear; near the end, the construction plans. Seize the plans, raise the Wonder and write your name into the Hall of Fame.
A living world
Seasons and map events
Seasons shape production and warfare. Barbarian raids, caravans, giant beasts and resource booms keep the map changing.
Choose your tribe
Every tribe has its own troops, walls and strengths. Pick the one that fits your style.
Aurian Empire
A disciplined sun-worshipping empire. Builds fields and village buildings at the same time, raises strong walls and fields costly but versatile troops.
Sylvan Clans
Swift, patient defenders of the forest. Large crannies, trappers that snare attackers before battle, and the fastest merchants.
Norrgard Clans
Cheap, numerous raiders of the cold north. Masters of plunder who see through part of every cranny.
Sunsand Dynasty
A wealthy river dynasty. Cheap defenders and aqueducts that amplify oasis bonuses make it an economic powerhouse.
Steppe Horde
Riders as fast as the wind. Build a command yurt instead of residence or palace; weak walls, devastating raids.
Bronze Phalanx
Masters of heavy infantry. Their healing temples bring back a large share of the fallen.
Fjord Raiders
Raiders from the waves. Their troops haul heavy loads and raider docks raise plunder capacity even further.

Frequently asked questions
Is Castruma free?+
Yes. The whole game is free to play. Gold is only for convenience and cosmetics; combat power can't be bought.
Is Castruma like Travian and other classic browser strategy games?+
Yes, it is the same genre: village building, resource production, armies, alliance warfare and an end-of-season race. But Castruma is an original game with its own tribes, rules, numbers and art; it is not affiliated with Travian or any other game.
How long does a world last?+
Each world is one season and its length is shown in the world list. The season ends when the Wonder is completed or time runs out; the rankings go into the Hall of Fame.
Can I play in several worlds?+
Yes, you can join several worlds with the same account. You have one avatar per world.
Are new players protected?+
Yes. When you join you are under beginner's protection for a while and can't be attacked. If you attack someone, your protection ends early.
What happens to my village when I go on holiday?+
You can switch on vacation mode or appoint players you trust as sitters. If someone wants to play your account with you, make them an account partner.
What is a truce?+
A period announced for special days such as holidays. During a truce, attacks that land only leave greetings and no troops starve.
Can I play on my phone?+
Yes. Castruma works fully in mobile browsers and can be added to your home screen. Your account is the same on every device.
How many tribes are there and which should I pick?+
Several tribes are available in every world, each with its own troops and bonuses. Beginners do well with a tribe that has a strong defence and a balanced economy; see the Tribes guide for details.
