Games like OpenFront.io you can play in your browser

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 November 2026, including the places where they do better than ours.

OpenFront.io is a browser game where you start from one spot on a real-world map, 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. If you want that feeling in another game, here is the short answer:

• The closest thing, and the best known of the family: Territorial.io.
• The same kind of map war, with a single-player mode and a Steam version: FrontWars.
• Towers and roads instead of open land, with a king to protect: Kiomet.
• Short, sharp matches on a hidden map, with a ranked 1v1 ladder: generals.io.
• The board-game version, closer to Risk: War.app.
• A duel instead of a crowd, castle against castle: Battle of Castles.

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

How these games compare

All six are about taking ground from other players in real time, or close to it. They differ on the shape of the map, on how many people share a match, and on how long a match lasts.

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 We do not print the price of games we do not publish.

1. Territorial.io: the original map war

Territorial.io, by Territorial Endeavours, is the game most people reach for after OpenFront. You spread across a map pixel by pixel, balance growth against attack and push your borders until the map is yours. Its Google Play page promises rounds that "can finish in less than 5 minutes", historical and generated maps, big multiplayer battles and one-vs-one duels. It runs in the browser at territorial.io and on Android, where it shows ads.

Pick it if you want the same feeling with shorter rounds. We compared it with other games on a whole page of games like Territorial.io.

2. FrontWars: the same idea, with a Steam version

FrontWars plays in the browser at frontwars.io and is also on Steam. Its lobby, read on 4 November, offered classic free-for-all rooms on real regions such as the British Isles, filling up to 50 players, as well as single-player games, private lobbies, community maps and a map editor. A three-minute tutorial teaches you to expand, attack and build.

Pick it if you like OpenFront's maps and rhythm and want a single-player mode to practise.

3. Kiomet: towers, roads and a king

Kiomet is a free browser game with no install and no account. Its page describes "a map of towers and roads": you drag from one of your towers to another to send units along the roads, upgrade towers into mines, factories or cities, set supply lines, and make alliances by offering a handshake. Lose your King and you lose the game. A "Play with friends" button gives you an invite code; your friends join you on the public server or on a party server of your own.

Pick it if you like OpenFront's alliances but want a map made of places to hold, not open land.

4. generals.io: fast and unforgiving

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. It calls itself "fast-paced", and has team games, custom maps, leaderboards and a ranked 1v1 ladder that runs in seasons, with tournaments.

Pick it if you want OpenFront's tension in a few minutes, or a ladder to climb.

5. War.app: the board-game side

War.app, formerly Warzone, presents itself as a game for people who like the board game RISK, and says it is not affiliated with its publisher. You play alone or with friends, in the browser, on Android or on iOS, across many maps and custom rules. Many games are played in turns rather than in real time.

Pick it if you like the diplomacy of OpenFront more than its speed.

6. Battle of Castles: a duel, not a crowd

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 big shared map: it is a duel, one against one, or two against two. 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.

Where OpenFront is about the border, Battle of Castles is about the road between two castles. 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, and each level gives you a point to spend on a power, up to the super attack. A 1v1 match lasts nine minutes, a 2v2 twelve, and you never wait for a match. You win by taking every enemy castle, or by holding the most castles when time runs out.

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 OpenFront.io does better: a hundred players on one real-world map, alliances, clans, and nations to build. Battle of Castles stops at 2v2 and has no diplomacy.

What Battle of Castles does not do

• No big free-for-all. Matches are 1v1 or 2v2.
• No real-world map and no open land. You fight over castles linked by roads.
• No alliances or diplomacy. Your only ally is your teammate in 2v2.
• 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.

Which game for your situation

You want OpenFront without OpenFront: Territorial.io, or FrontWars if you also want a single-player mode.

You want alliances, but on a map of places to hold: Kiomet.

You have five minutes and want to climb a ladder: generals.io.

You prefer turns and diplomacy to speed: War.app.

You would rather face one opponent than a hundred, or bring one friend: Battle of Castles.
