Tic Tac Pro

AI Challenge & Strategy Guide

About Tic Tac Pro

Welcome to Tic Tac Pro, the ultimate evolution of the classic pencil-and-paper game. While traditional Tic-Tac-Toe often ends in a draw between experienced players, our version introduces a state-of-the-art AI opponent designed to challenge your strategic thinking at every level.

Unlike random number generators used in basic games, our "Unbeatable AI" utilizes the Minimax algorithm, a decision rule used in artificial intelligence, decision theory, and game theory. It looks ahead at every possible move to ensure it never loses. Can you find the perfect strategy to force a draw, or will you succumb to the machine?

How to Play Tic Tac Toe

The Rules

  • â–º The game is played on a grid that's 3 squares by 3 squares.
  • â–º You are X, your friend (or the computer) is O. Players take turns putting their marks in empty squares.
  • â–º The first player to get 3 of her marks in a row (up, down, across, or diagonally) is the winner.
  • â–º When all 9 squares are full, the game is over. If no player has 3 marks in a row, the game ends in a tie.

Strategy Guide: How to Win (or not lose)

To beat the computer (or at least tie), you need to make use of a little strategy. Strategy is the art of figuring out what you should do to win. Here are a few tips:

  • â–º Take the Center: The center square is the most powerful position on the board. It gives you the most possible ways to make a line (4 ways: vertical, horizontal, and two diagonals).
  • â–º Corner Defense: If you can't take the center, take a corner. Corner moves can often trap an opponent into a losing position.
  • â–º Block the Win: Always look at your opponent's move. If they have two in a row, you must play in the third remaining square to block them.
  • â–º Create a Fork: Try to create a scenario where you have two ways to win. Your opponent can only block one, leaving you free to win on the next turn.

The Science Behind the AI: Minimax Algorithm

The "Unbeatable" difficulty in Tic Tac Pro is powered by a concept in combinatorial game theory called the Minimax algorithm. This is a recursive algorithm used for decision-making in game theory and artificial intelligence.

Here is how it works conceptually:

  • â–º Look-ahead: The AI simulates every possible move it can make, then every possible response you can make, then its response to that, and so on, until the game ends (win, loss, or draw).
  • â–º Scoring: It assigns a score to each terminal state: +10 for a win, -10 for a loss, and 0 for a draw.
  • â–º Minimizing & Maximizing: The AI (the "Maximizer") always chooses the move that leads to the highest possible score. It assumes you (the "Minimizer") will always play perfectly to give the AI the lowest possible score.
  • â–º Optimal Decision: By working backwards from the end of the game up to the current state, the AI determines the absolute best move to guarantee it never loses.

In a game like Tic Tac Toe, the state space is small enough (362,880 possible terminal positions) that standard computers can calculate the perfect move in milliseconds. This is why the generic "Hard" mode feels like playing against a grandmaster.

Game Theory: The Mathematical Certainty

Tic Tac Toe is what mathematicians call a zero-sum game of perfect information. "Perfect information" means both players know the state of the game at all times (unlike Poker). "Zero-sum" means one player's gain is exactly the other player's loss.

It has been mathematically proven that if both players play optimally, the game will always end in a draw. There is no sequence of moves that allows Player 1 to force a win against a perfect Player 2. However, human players often make "sub-optimal" moves due to distraction or lack of foresight. Our AI is programmed to exploit these tiny mistakes immediately, turning a potential draw into a victory.

The History of Tic Tac Toe

Games played on three-in-a-row boards can be traced back to ancient Egypt, where such game boards create a lineage of simplified strategy games. An early variation of Tic Tac Toe was played in the Roman Empire, around the first century BC. It was called Terni Lapilli and instead of having any number of pieces, each player only had three, thus they had to move them around to keep playing.

The game's simplicity makes it ideal as a pedagogical tool for teaching the concepts of good sportsmanship and the branch of artificial intelligence that deals with the searching of game trees.
