You think you know how it works. Three marks in a row. A grid drawn on a napkin. It’s the first game most kids ever learn, and for many, it’s the first one they get bored of. But the tic tic tac toe game—or what most people just call Noughts and Crosses—isn't quite as shallow as that 3x3 box makes it look. Honestly, if you’re still drawing a grid and hoping for the best, you’re missing the actual logic that makes this thing a foundational piece of game theory.
It’s solved. That’s the reality. Mathematically, if both people know what they’re doing, the game ends in a draw every single time.
Every. Single. Time.
But humans aren't computers. We get distracted. We make "trap" moves. We get cocky. That's where the real fun lives. Whether you call it tick tack toe, tic tic tac toe game, or OXO, the mechanics are a window into how our brains process spatial patterns and predictive reasoning.
The Brutal Math of a Solved System
Let's look at the numbers because they’re actually kinda wild when you break them down. In a standard game, there are 255,168 possible ways the game can play out. That sounds like a lot, right? It isn't. Not for a computer. When you strip away the rotations and reflections—basically the same board just turned sideways—there are only 765 essentially different positions.
Computer scientists like Donald Michie were obsessed with this back in the day. In 1961, Michie built a "computer" out of 304 matchboxes called MENACE (Matchbox Educable Noughts and Crosses Engine). It didn't have a processor. It used beads and cardboard. Each matchbox represented a possible board state. If the "machine" won, it got more beads of that color, "learning" through reinforcement.
It worked. Eventually, a pile of matchboxes became unbeatable.
If a literal pile of trash can master the tic tic tac toe game, why do we still lose to our nephews? Because we play with our gut, not with an algorithm. Most people play reactively. You see two Xs, you put an O to block. That’s defense. Defense doesn't win; it just delays losing. To actually dominate, you have to force a "fork"—a situation where you have two ways to win, and your opponent can only block one.
How to Actually Win (The Corner Strategy)
Forget the center for a second. Everyone screams about the center. Yes, the center is the most valuable square because it’s part of four possible winning lines. But playing the center first is predictable. It leads to a draw faster than anything else.
If you want to win a tic tic tac toe game against someone who isn't a grandmaster, start in a corner.
Why? Because corners are sneaky. If you take a corner and your opponent doesn't take the center immediately, they’ve basically already lost. If they take an edge—the middle spots on the sides—you can set up a fork that is impossible to escape.

Imagine this:
- You: Top Left Corner.
- Them: Right Edge.
- You: Bottom Right Corner.
Now you have two corners opposite each other. If they don't play the center now, you take another corner, and suddenly you have two paths to victory. It’s a classic trap. Most casual players don't see the diagonal threat until it’s too late. They’re too focused on the rows and columns.
The Complexity of Variant Play
If the basic 3x3 grid is too "solved" for you, the world of gaming has evolved. We aren't just stuck in 1950.
Have you ever tried Ultimate Tic Tac Toe? It’s basically the "Inception" version of the game. You have a 3x3 grid, but each of those nine squares is itself a tiny 3x3 tic tac toe board. Where you play in the small board determines which small board your opponent has to play in next.
It’s a nightmare. A beautiful, strategic nightmare.
In this version, you might intentionally lose a small board to gain a strategic advantage in the larger meta-game. It shifts the tic tic tac toe game from a simple pattern-matching exercise into a complex resource-management puzzle. Mathematicians love it because it removes the "solved" nature of the original. You can't just memorize 765 positions anymore. You have to think five moves ahead, considering how your current move constrains your opponent's future options.
Why Kids Need This Game (And Why Adults Forget It)
Developmental psychologists often point to these types of games as crucial for "executive function." It’s about inhibitory control. You want to put your X in the bottom corner because it feels good, but you have to inhibit that urge to block the opponent's winning line on the top row.
It teaches kids about "Theory of Mind"—the realization that the person sitting across from you has their own plan, their own goals, and is actively trying to thwart yours.
But as adults, we sort of dismiss it. We call it "child's play."
That’s a mistake. The tic tic tac toe game is the purest form of Zero-Sum logic. In a zero-sum game, one person's gain is exactly equal to the other person's loss. There is no win-win. There is only "I win, you lose" or "We both tie." Understanding this is the bedrock of higher-level economics and military strategy. John von Neumann, the father of modern game theory, used these exact types of simple games to model how superpowers might behave during the Cold War.
When you're staring at that grid, you're doing a simplified version of nuclear standoff math. No joke.
Common Misconceptions and Errors
People think the first player always wins.
Not true.
The first player has an advantage, sure, but in a perfectly played tic tic tac toe game, the result is always a draw. If you’re the second player (the O), your entire job is to minimize the X's ability to create a fork.
The biggest mistake? Playing on the edges.
The edges (the middle-top, middle-bottom, middle-left, middle-right) are the weakest squares on the board. They only contribute to two possible winning lines. Corners contribute to three. The center contributes to four. If you're O and X takes the center, you must take a corner. If you take an edge, you’re dead. It’s a mathematical certainty.
Variants You Should Actually Try
- 3D Tic Tac Toe (Qubic): Played on a 4x4x4 cube. It’s much harder to track the lines when they move through three dimensions of space.
- Wild Tic Tac Toe: Both players can choose to place either an X or an O on any turn. The first person to complete a line of three of the same symbol wins. It sounds chaotic because it is.
- Notakto: Both players play with the same symbol (usually X). The person who completes a line of three loses. It turns the game into a "misere" play game, where the goal is to avoid the winning condition.
The Cultural Footprint
This game isn't just on paper. It was one of the first video games ever made. OXO, developed by Alexander S. Douglas in 1952 at the University of Cambridge, ran on the EDSAC computer. It used a rotary telephone dial for input and displayed the grid on a cathode-ray tube.
Think about that. Before Call of Duty, before Mario, before Pong, there was a tic tic tac toe game flickering on a vacuum-tube screen in a lab in England.
It’s also a staple of pop culture. Remember the movie WarGames from 1983? Matthew Broderick’s character has to teach a runaway military AI (WOPR) that some games—like nuclear war and tic tac toe—are "strange" because the only winning move is not to play. It was a profound metaphor for the Cold War policy of Mutually Assured Destruction (MAD).
How to Get Better Right Now
Stop playing randomly. If you want to stop being the person who draws every game or, worse, loses to someone who knows the "trap," you need a mental checklist.
- Win: If you have two in a row, play the third.
- Block: If the opponent has two in a row, you have to block them.
- Fork: Create a situation where you have two ways to win.
- Block Opponent’s Fork: This is the hard part. You have to look ahead and see if your opponent is setting up a double-threat.
- Center: Take it if it’s open (unless you're following a specific corner strategy).
- Opposite Corner: If your opponent is in a corner, play the opposite corner.
- Empty Corner: Take any remaining corner.
- Empty Side: Take any remaining edge.
If you follow that hierarchy in every tic tic tac toe game, you literally cannot lose. You might not win—because, again, the game is solved—but you will never see that "L" on your side of the screen or paper ever again.
Final Tactics for Mastery
Next time you find yourself waiting for a flight or sitting at a restaurant with a paper placemat, don't just scribble. Think about the grid as a set of intersecting lines.
The tic tic tac toe game is a test of attention. Most people lose because they stop paying attention to the diagonals. We are hard-wired to look at horizontal and vertical lines first. It’s a glitch in our visual processing. Exploit that. Force your opponent to defend on a diagonal while you're secretly building a horizontal threat.
It’s a tiny bit of psychological warfare in a 3x3 box.
Next Steps for Players:
- Practice the "Center-Opposite" Defense: If you go second and the first player takes a corner, you must take the center. If they take the center, you must take a corner. Memorize these two responses to ensure a draw every time.
- Transition to Gomoku: If the 3x3 grid feels too small, try Gomoku (Five in a Row) on a 15x15 or 19x19 board. The principles are similar, but the complexity is exponentially higher.
- Analyze Your Losses: If you lose a game of tic tac toe, it’s because you missed a "Block" or "Fork" opportunity. Go back and find the exact move where you stopped looking two steps ahead.
The game is simple, sure. But simplicity is where the most elegant logic hides. Stop playing like a kid and start playing like a strategist. Even a "solved" game has room for a little bit of human cleverness.
