Four Discs (often known as Connect 4) is a classic for a reason, and this version is a polished, no-nonsense adaptation. The gameplay is exactly what you expect: drop your colored discs to get four in a row before your opponent. What makes this specific app worth the download is the variety of difficulty levels. The 'Expert' AI is surprisingly tough and will punish any tactical lapse, making it a great tool for players looking to sharpen their strategy.
The inclusion of a same-device multiplayer mode is perfect for passing the time with a friend during a commute or at a cafe. The UI is clean, the animations are smooth, and the 'undo' button is a welcome feature for those accidental taps. Itβs a simple game executed with a high level of polish and no intrusive ads, which is a breath of fresh air on the App Store. For a casual board game experience, you can't go wrong here.
Weβve all played Connect Four. Itβs a solved game, and this app doesn't do a single thing to modernize it or make it more interesting. The graphics are uninspired, and the 'clink' of the discs sounds more like a digital glitch than actual plastic hitting a grid. Itβs the kind of game you download for a five-minute flight and then delete immediately after landing.
The AI is predictable on lower settings and feels like it's cheating on higher ones, which is a common shortcut for developers who don't want to program actual logic. There are a dozen better versions of this on the App Store with better graphics, online play, and skin customization. This feels like a high school coding project that somehow made it onto the marketplace. I don't see the point in it.
Performance: Stable, but the touch detection is occasionally finicky.
Buy if: You have a deep nostalgia for 4-in-a-row and no internet connection.
Skip if: You want modern features or competitive online play.

Try to place your first few discs in the center columns. This gives you the most opportunities to connect four in multiple directions and limits your opponent's options.
Always check for 'double threats' where your opponent can win in two different spots on their next turn. If you see them setting one up, you must block it immediately.
This version currently focuses on local multiplayer and AI challenges.
