How to Play Four Square: Simple Rules for Endless Fun

Four Square is a backyard classic that’s easy to learn but tough to master. All you need is a ball, some chalk, and four players ready to compete. The court is divided into four squares—numbered 1 to 4—and the game revolves around quick reflexes, control, and a bit of strategy.

One of the core rules? Every hit must be underhand. No overhand slams allowed—this keeps things fair and keeps the game flowing. The ball is served from the highest-numbered square (usually 4) into any other square, and play continues as players hit the ball from one square to another after only one bounce.

Here’s where precision matters: Hitting on or over the line is “Out.” That includes both inside lines and the outer boundary. If the ball lands on any line, the hitter is out, and the next player rotates in. Also, if the ball bounces twice in your square, or you hit it before it bounces, you’re out. Simple—but it catches even seasoned players off guard.

Another quick way out? Hitting the ball out of bounds. Whether it flies too far or rolls off the court, clean contact within the lines is a must. The goal is to stay in, climb the ranks by knocking others out, and claim the top square as your throne.

Four Square thrives on speed and focus. It’s not just a kid’s game—it’s a test of concentration and timing. With these rules in mind, anyone can jump in, serve the ball, and join the friendly (or fiercely competitive) battle for dominance in the court. All it takes is a bounce, a hit, and a little nerve.
