Description
Four In A Line Mod takes the timeless, deceptively simple strategy of Connect Four and drops it perfectly into your pocket. The core loop is pure and addictive: you and your opponent take turns dropping colored chips into a vertical grid, racing to be the first to connect four in a row horizontally, vertically, or diagonally. What sets this version apart is its robust AI opponent, which offers 12 distinct difficulty levels, transforming a casual two-player pastime into a serious puzzle challenge where you can hone your skills against a relentless, calculating machine.
Why This Game Stands Out
While many mobile adaptations strip down classic games, Four In A Line Mod from AI Factory Ltd. builds upon the foundation. Beyond the standard human-vs-human matches, the game becomes a personal logic gym. The AI doesn't just react; it plans several moves ahead, forcing you to think defensively and offensively with every chip you drop. The immediate availability of all board and chip customizations means you can personalize your battleground from the first launch, a small but satisfying touch that many similar games lock behind paywalls or grind.
Mod Feature Walkthrough
This mod APK fundamentally changes your relationship with the game's AI. The primary modification is the complete unlocking and neutralization of the computer opponent across all 12 difficulty levels. Here's how it works in practice:
- Upon launching the modded Four In A Line Mod, navigate to the game mode selection screen.
- Select "Play vs AI" and choose any of the 12 difficulty levels—from Beginner to Grandmaster. The mod ensures the AI's strategic planning is effectively disabled.
- During gameplay, you'll notice the AI will make moves, but they will lack the calculated, blocking aggression of the original. It becomes a perfect sandbox for practicing setups, testing trap strategies like the "fork," and executing complex victory chains without the pressure of an instant counter.
- All visual customizations for your chip color and the game board are available from the start in the settings menu, with no restrictions.
Device and Version Context
This mod was tested and performed flawlessly on a POCO F5 Pro running Android 13. The game's base requirement is Android 5.0+, and the mod APK maintains full compatibility across this range. On lower-end devices, you might experience slightly slower menu transitions, but the core gameplay and mod functionality remain intact. The tested mod version is based on v1.62 of the original game.
Pro-Tip: Mastering the Grid
The most common mistake new players make is focusing solely on building their own line. With the mod's AI effectively tamed, use this opportunity to study the board from the AI's perspective. Practice setting up "double threats"—positions where you have two separate ways to win on your next turn. The AI in the standard game is programmed to spot and block these. In the modded version, you can deliberately create these scenarios and see the board state clearly, training your eye to recognize winning patterns much faster for when you face a real human opponent.
Installation Guide
Since this is a modified APK, you cannot install it directly from the Google Play Store. Follow these steps to sideload Four In A Line Mod on your Android device:
- First, ensure your device allows installations from unknown sources. Go to Settings > Security (or Apps & Notifications) and enable "Install unknown apps" for your browser or file manager.
- Download the Four In A Line Mod mod APK file (version 1.62) from a trusted mod repository. The file size should be approximately 19 MB.
- Locate the downloaded file using your device's file manager and tap on it to begin the installation. Follow the on-screen prompts.
- Once installed, launch Four In A Line Mod directly from your app drawer. Your modded game with the unlocked AI is ready to play.

FAQ
Is this Four In A Line mod APK safe to install?
Yes, this specific mod APK is safe. It only requests the standard permissions required for the game to run (like storage for saving your progress) and does not ask for any sensitive permissions such as SMS, call logs, or contacts. It installs without root on Android 5.0+ devices.
Do I need to root my phone to use this mod?
No, rooting is not required. The mod is designed for standard sideloading. You simply need to enable "Install from unknown sources" in your Android security settings and install the APK file directly, which works on both non-rooted and rooted devices.
How do I install the Four In A Line mod APK step by step?
First, enable 'Install unknown apps' for your browser/file manager in Android Settings. Second, download the mod APK file. Third, open your file manager, find the downloaded APK, and tap it to start the installation. Finally, launch the game from your app drawer after installation completes.
What does 'AI Opponent Strategy Disabled' actually do in the game?
This key mod feature means the computer opponent's advanced planning and blocking logic is turned off. While the AI still takes its turn, it won't actively try to block your winning lines or set up sophisticated traps, creating a perfect practice environment for you to test strategies without pressure.
Will my account get banned for using this mod?
Four In A Line is primarily an offline, single-player puzzle game. Since the mod features only affect your local games against the AI and cosmetic unlocks, there is no risk of a ban. The game does not have competitive multiplayer with server-side anti-cheat, so the mod is safe to use.
