4 in Row Mania

Drop your discs and line up four before your rival does—simple rules, brutal mind games.

Connect Four has been around forever, but 4 in Row Mania strips it down to the essentials: a grid, two colors, and your ability to think one move ahead. I lost my first three rounds to the CPU because I kept chasing my own rows instead of watching the diagonals. That's the trap—every drop feels safe until you realize you've handed your opponent a vertical stack on a silver platter. The real fun starts when you stop playing offense and start setting traps. A friend and I spent an entire lunch break going back and forth, and the moment I finally saw the diagonal coming together—two discs here, one there, and a gap ready to cap it—it was pure satisfaction. The CPU on harder settings actually punishes greedy column choices, which forced me to rethink how I used the middle lanes. Those center columns open up more angles than the edges, and abandoning them too early is a death sentence. Whether you're facing the computer or passing the keyboard back and forth, 4 in Row Mania nails the pacing. Games are short enough to binge but deep enough that losing stings just a little. My advice: don't just block the obvious three—start building a second threat on the other side of the board while your opponent scrambles. That's when the game really clicks.

Two players (or player vs CPU) take turns, dropping one piece of their colour into a desired column. The first one to achieve a horizontal, vertical or diagonal row of four wins.

Always scan the diagonals before you commit—most wins come from a sneaky four that neither player saw coming. Claim the center column early if you can; it gives you the most potential lines to attack and defend. When facing the CPU, bait it into blocking your three while you quietly build a separate two-disc threat on the other side. Don't just mirror your opponent's moves if you're player two—force them to react to your tempo instead. Try to create two three-in-a-rows at the same time; your opponent can only block one of them. If a column has three of your discs already, make sure dropping a fourth there actually wins—sometimes it just fills a dead end.
