If you've ever wondered what the best first move in Tic Tac Toe is, the short answer is simple:
Play the center square whenever it's available.
While Tic Tac Toe is a solved game (meaning perfect play always ends in a draw), choosing the right opening move dramatically increases your chances of beating opponents who make mistakes.
In this guide, we'll explain why the center is the strongest opening, when corners become the better option, and how to respond to every common opening.
Why the Center Is the Best First Move
The center square is the most valuable position on the board.
⬜ ⬜ ⬜
⬜ ❌ ⬜
⬜ ⬜ ⬜
Why?
- It belongs to 4 possible winning lines
- Horizontal
- Vertical
- Main diagonal
- Secondary diagonal
- Corners belong to only 3 winning lines
- Edge squares belong to just 2 winning lines
This means playing the center gives you the greatest number of future winning opportunities.
What If the Center Is Already Taken?
If you're playing second and your opponent starts in the center, your best move is usually a corner.
⭕ ⬜ ⬜

Avoid opening on an edge whenever possible.
Corner moves create more opportunities to build forks (positions where you threaten two wins at once).
Should You Ever Start in a Corner?
Yes.
While the center is mathematically stronger, opening with a corner is still considered optimal.
❌ ⬜ ⬜

Corner openings often confuse inexperienced players because they create diagonal threats earlier in the game.
Against perfect play, the result is still a draw.
Against human players, corners can lead to more mistakes.
Why Edge Squares Are Usually a Bad Opening
Starting on an edge gives away too much flexibility.

Edge openings:
- Control only two winning lines
- Make forks harder to create
- Give your opponent stronger responses
Unless you're experimenting, edge openings are generally not recommended.
Best Response to Every Opening
Opponent Starts in the Center
Your move:
- Choose any corner.

Take the center immediately.

This prevents most early traps.
Opponent Starts on an Edge
Again, take the center.

This usually gives you the strategic advantage.
Common Beginner Mistakes
Ignoring the Center
Many new players immediately choose a corner.
While corners are good, giving your opponent the center is rarely ideal.
Missing Fork Opportunities
A fork occurs when one move creates two separate winning threats.
Your opponent can only block one of them.
Learning forks is one of the biggest improvements you can make.
Chasing Instead of Planning
Instead of reacting every turn, think one or two moves ahead.
Ask yourself:
- Can my opponent create a fork?
- Can I force them to defend?
- Am I controlling the center?
Can You Always Win With the First Move?
No.
Tic Tac Toe has been mathematically solved.
If both players make perfect decisions, every game ends in a draw.
However, choosing the correct opening dramatically increases your chances against real opponents because people frequently overlook forks, diagonal threats, and blocking moves.
Quick Strategy Checklist
✅ Take the center whenever possible.
✅ If the center is occupied, choose a corner.
✅ Avoid opening on an edge.
✅ Watch for fork opportunities.
✅ Block your opponent's forks before your own attacks.
