Connect Four Review: Simple Rules, Deep Strategy

The bottom line: rules a child grasps in a minute hiding strategy that takes years, and the browser version is a quick, sharp way to get a game in.

Connect Four is the game everyone thinks they have mastered until they play someone who actually has. I grew up dropping discs into that yellow frame, and coming back to the browser version for this review reminded me how much real thinking sits under the cartoon simplicity. It is not quite a five for me, mostly because of how the matchups play out, but it is a confident four and a game I keep recommending to people who want depth without a rulebook.

How it plays

Two players take turns dropping a disc into one of seven columns on a seven-by-six grid. Gravity pulls each disc to the lowest open slot in that column, so you never place freely, you only choose a column. The first player to line up four of their own discs in a row, horizontally, vertically or diagonally, wins. If the board fills with no line of four, it is a draw. That is everything, and a five-year-old can be playing within a minute.

What works

The gap between learning it and being good at it is where the magic lives. Every disc does two jobs at once, building my own threats while blocking yours, and the gravity rule means a column I want can be poisoned by what it sets up for my opponent on top. Good play is about creating two threats at the same time so the other side can only stop one, and spotting those double attacks a few moves out is genuinely tense. The browser version I played has a solid computer opponent that punishes lazy moves, and pass-and-play makes it a great quick game with someone next to me.

What does not

The honest weakness is that Connect Four is a solved game, and the first player can force a win with perfect play by starting in the center. A flawless computer on the hardest setting can feel unbeatable as a result, and a couple of the AI tiers either play too softly or too perfectly with little middle ground. Against a much weaker or much stronger human, matches can also end fast and one-sided, so it shines most between players of similar skill. The presentation is plain, which suits me but will not wow anyone. None of this is a dealbreaker, but together they keep it off the top score.

Who it suits

This is for people who like quick, head-to-head strategy with a friend or a sharp computer. If you enjoy chess-lite thinking where you read a few moves ahead and set traps, you will get a lot out of it. If you want long, sprawling games or solo progression, it will feel slight. For a fast, repeatable battle of wits, it is hard to beat.

My verdict

Connect Four packs surprising tactical depth into rules anyone can learn instantly, and the free browser build is a clean, no-install way to test yourself against the computer or a friend. It loses a point for being a solved game and for some uneven matchups, but the core duel is excellent.
