Games like Conflict of Nations and Supremacy 1914, but faster

This page is written by the team behind Battle of Castles, one of the six games below. We say it here rather than at the bottom. The other games are described from their own pages, read on 4 and 5 November 2026, including the places where they do better than ours.

Conflict of Nations, now listed as Supremacy: World War 3, describes its own wars as "campaigns spanning days or even weeks". Supremacy 1914, by the same publisher, plays on persistent maps with up to 500 players, and its Steam page quotes a review saying a game "may go on for months". If you love the map and the conquest but want to finish the war in one sitting, here is the short answer:

• A whole world war in fifteen minutes: SECOND STRIKE.
• Rounds that can end in under five minutes: Territorial.io.
• A big real-world map, alliances included: OpenFront.io.
• A map of towers and roads you can drop into at any time: Kiomet.
• Short, sharp matches with a ranked ladder: generals.io.
• A nine-minute duel between castles, 1v1 or 2v2: Battle of Castles.

Play Battle of Castles in your browser: free, no account, nothing to download.

How these games compare

Going faster has a price. All six keep the map and the conquest in real time, but they drop most of the research, economy and long diplomacy that fill a campaign of several weeks. The table says what stays.

Prices change: check the store page before you buy. We do not print the price of games we do not publish.

1. SECOND STRIKE: a world war in fifteen minutes

SECOND STRIKE is the closest answer to the question. Its war game is "a real-time world war on a 3D globe of the real Earth": you spawn anywhere, grow by sending troops at the land next to you, take real cities, sign pacts and break them, and build silos, carriers and satellites. Its site lists a 15-minute world war, a 5-minute Blitz on one region, and online wars of up to 200 players, in the browser with no download.

Pick it if you want the real map, the nations and the nukes, and nothing else on this page will do.

2. Territorial.io: the shortest war

Territorial.io, by Territorial Endeavours, strips the idea down: you spread across a map pixel by pixel and balance growth against attack. There are no units to research and no trade. Its Google Play page promises rounds that "can finish in less than 5 minutes", historical and generated maps, and big multiplayer battles.

Pick it if you want conquest and nothing to manage. See also our page of games like Territorial.io.

3. OpenFront.io: real maps, alliances and a crowd

OpenFront.io starts you from one spot on a real-world map, and you spread your nation across it, make or break alliances and fight for the whole map. Its lobby shows free-for-all rooms of up to 100 players, team games and a ranked mode. It is in alpha, and it is also sold on Steam.

Pick it if the alliances matter as much to you as the war. See also our page of games like OpenFront.io.

4. Kiomet: a war you can leave

Kiomet is a free browser game with no install and no account. On a map of towers and roads you send units to capture towers, upgrade them into mines, factories or cities, set supply lines and make alliances with a handshake. You keep some of the building of a long campaign, without any timer to come back to. Lose your King and you lose the game.

Pick it if you want a little economy and a world that is there when you open it. We wrote a whole page of games like Kiomet.

5. generals.io: the fastest thinking

generals.io is a free browser game by MUGA Gaming: protect your general, take land on a grid hidden by fog of war, and capture the other generals. There is no world map and no nation, but there are team games, custom maps and a ranked 1v1 ladder that runs in seasons.

Pick it if you want the sharpest decisions of a campaign in a few minutes. We wrote a whole page of games like generals.io.

6. Battle of Castles: a war in nine minutes

Battle of Castles is a real-time strategy game played in the browser at app.battleofcastles.com, and on Android through Google Play. It is not a grand strategy game: there are no nations, no research and no world map. What stays is the part that made you open the map every day: choosing where to attack, and holding a front while you do it, here in a match of nine minutes, or twelve in 2v2, with no timer to come back to.

You start with one castle. Point at a road and your castle sends half its garrison down it, every second, until you call the order off. Neutral castles are there to be taken, and each castle you hold produces troops and experience. A tower on a road cuts down the troops that march past, a wall blocks it and stops arrows, a catapult pounds the castle across the way. Experience brings levels, each level gives you a point to spend on a power, up to the super attack, and mana buys defences or one decisive blow. You never wait for a match.

Every match pays gold, won or lost, and gold buys nothing but decoration: no castle you buy hits harder than the one you started with.

To play with a friend, create a team and share its code: you can challenge each other one on one or team up for a 2v2. Our guide to playing with a friend walks through it.

Where Conflict of Nations does better: everything that needs time. Nations, research, an economy, modern units, coalitions and a war that goes on all month. Battle of Castles has none of those.

What Battle of Castles does not do

• No grand strategy. No nations, no research, no economy beyond your castles.
• No world map. You fight over castles linked by roads.
• No alliances or diplomacy. Your only ally is your teammate in 2v2.
• No big free-for-all. Matches are 1v1 or 2v2.
• No modern units. It is a medieval game of soldiers, towers, walls and catapults.
• No offline play. Every match runs on our servers, so you need a connection.
• No App Store app. On Android there is the Google Play app; on a computer or an iPhone, the browser.
• Landscape only on phones.
• No in-game chat. With a friend, use your usual call or messaging app.
