![]() Here is what I do in step 3: scan every cell, check if put token on that cell creates a fork, then put it there. However, the way it attacks is not perfect. I've followed these step, and the computer never loses. Option 2: If there is a configuration where the opponent can fork,Ħ) Opposite Corner: If the opponent is in the corner, play the (Playing a corner in this scenario creates a fork for "X" to win.) Opposite corner as well, "O" must not play a corner in order to win. ForĮxample, if "X" has a corner, "O" has the center, and "X" has the Long as it doesn't result in them creating a fork or winning. Option 1: Create two in a row to force the opponent into defending, as Highest priority in the following table.ġ) Win: If you have two in a row, play the third to get three in aĢ) Block: If the opponent has two in a row, play the third to blockģ) Fork: Create an opportunity where you can win in two ways. And I found the strategy on Wikipedia is suitable for my presentation project:Ī player can play perfect tic-tac-toe if they choose the move with the ![]() And because tic-tac-toe has so few moves and possible outcomes, this algorithm can easily fit onto a microcontroller.I've already read many Tic Tac Toe topics on StackOverflow. By following the path that results in the highest (optimal) score, the player can maximize their chances of winning while minimizing their chances of losing. The algorithm is quite simple, as a tree of moves is generated for each possible turn down to a certain depth, and a score is assigned to each outcome for a given player- win, lose, or draw. The AI for his device isn't a neural network like most would assume, but rather a small implementation of the minimax algorithm. This fact about tic-tac-toe lets a program have the possibility to never lose, a goal that Michael Klements wanted to achieve with his DIY Tic-Tac-Toe Shield that features an AI opponent. The game is considered "solved", which means that two players who play perfectly result in a tied match. ![]() Tic-tac-toe is a classic game that involves placing X's and O's onto a 3x3 grid of squares and trying to get 3 of your shape in a row. ![]()
