A real 4X keeps the whole loop: fog of war to scout, land to settle, an economy and tech tree to develop, and armies to conquer with. The four below respect all of that instead of bolting a strategy skin onto a city-builder with energy timers. Three are native to mobile, one is a faithful open-source remake, and every entry is upfront about where the phone version pinches.
1. The Battle of Polytopia
Polytopia is the cleanest full 4X on a touchscreen: it compresses explore, expand, exploit and exterminate into matches that end in about 30 turns, and it was built for phones from the start, so nothing feels ported or stretched. It is the pick for players who want the whole genre loop in a session that fits a bus ride.
Developer Midjiwan AB first released it in 2016, and it stays current: the iOS build is version 2.17.3, updated September 7, 2026. The four base tribes are free, the rest cost a dollar or two each, and there are no energy timers or ads. A separate paid version also ships on Steam for $14.99.
What it trades is scale. There is no sprawling tech web or deep diplomacy layer, just a tight distillation with 16 tribes that each change how you open. It pairs naturally with the wider pool of mobile strategy games once you want something longer.
Best for: players who want a complete 4X in short, repeatable matches.
Skip if: you want deep tech trees, diplomacy and hours-long games.
2. Civilization VI
If you want the genuine article with nothing cut, Aspyr’s port of Civilization VI is the full PC game on your phone. Every system survives the move: districts, religion, the complete tech and civics trees, and the expansions. It is the no-compromise choice for players who finish long campaigns.
The original released in 2016 from Firaxis Games; the mobile port is published by Aspyr, and the Android and iOS listings are free to download with the full game and expansions unlocked by in-app purchase. New players get 60 turns free to test it before buying.
The corners it cuts are your wallet and your battery. The full unlock and expansion passes add up, the interface is cramped on a phone and far better on a tablet, and it wants a newer device. As a no-compromise 4X, though, nothing else on Android touches it.
Best for: players who want the complete Civilization systems on a tablet.
Skip if: you are on a small or older phone, or want to pay once and own everything up front.
3. Unciv
Unciv is a faithful, open-source rebuild of Civilization V that runs on almost anything and costs nothing, with no ads and no in-app purchases. If you want a real, deep 4X for free, this is the one to install first.
It is community-developed and updated constantly: the latest release is version 4.21.19, published September 9, 2026 on GitHub, and it is available on Google Play and F-Droid. Because it is light, it runs smoothly on old and low-end Android phones that choke on Civilization VI.
What it trades is polish and presentation. The interface is functional rather than pretty, and it mirrors Civilization V rather than the newer entry. For a free, full-fat 4X with mod support, that is a small price.
Best for: players who want a complete, free Civ-style 4X on any device.
Skip if: you want modern presentation and official support.
4. Age of History 3
Age of History 3 pushes past classic 4X toward grand strategy, letting you take a historical or custom nation across a detailed world map through diplomacy, economy and war. It is the pick when you want map-painting and alliances more than a tight tactical loop.
Developer Lukasz Jakowski released it on Steam on October 23, 2024, for $9.99, and the Android version is a paid app with a free “Lite” edition to try first. It leans heavily on scenarios and a deep editor, so it rewards players who like to build their own maps and campaigns.
What it trades is accessibility. The interface is dense, the tutorials are thin, and the presentation is utilitarian. If you can push through the first hour, it offers more historical scope than anything else on this list.
Best for: players who want grand-strategy scope and a map editor on mobile.
Skip if: you want a gentle learning curve or a polished interface.
Which 4X should you install?
Start with Polytopia if you want the whole 4X loop in short matches, and pay for the tribes you enjoy. Choose Civilization VI, ideally on a tablet, when you want every system and are willing to spend. Install Unciv for a free, deep Civ V that runs on any phone. Pick Age of History 3 when map-painting grand strategy is the goal. For more picks, see our best mobile strategy games and best free mobile strategy games.
Frequently asked questions
What is the best 4X strategy game on Android?
The Battle of Polytopia is the best all-round pick because it keeps the full 4X loop in fast, touch-built matches and is free to start. If you want maximum depth and will pay for it, Civilization VI is the most complete option, and Unciv is the best free game with no purchases at all.
Are there free 4X strategy games on Android?
Yes. Unciv is completely free with no ads or in-app purchases, and it is a full Civilization V-style 4X. Polytopia is free to start with four tribes, then charges a dollar or two per extra tribe. Both are on Google Play, and Unciv is also on F-Droid.
Is Civilization VI on Android the full game?
Yes. Aspyr’s Android port includes the full game and its expansions, with every system from the PC release. The app is free to download with a 60-turn trial, and the full game unlocks through in-app purchase. It runs best on a recent tablet rather than a small phone.
Are these 4X games on iPhone too?
Polytopia and Civilization VI both ship on iOS with the same features as their Android builds. Unciv and Age of History 3 are focused on Android, so iPhone players should choose Polytopia or Civilization VI. All store links above list the platforms each game supports.
What makes a game 4X instead of just strategy?
A 4X game is built on four pillars: explore the map, expand your territory, exploit resources through an economy and tech tree, and exterminate rivals. Many mobile “strategy” games drop one or more of these for timers or city-building. The games here keep all four intact.
