Tic-Tac-Toe

This is custom implementation with minor improvements of a popular board game "Five in a row"(or "Gomoku", or tic-tac-toe an enlarged board). Where you play against AI.

Try it here: https://game-five-in-a-row.herokuapp.com/ (Maybe it will be necessary to wait a bit before game starts)

How to play?

The aim of the game is to form a sequence of 5 (or more) noughts or crosses in a row (vertically, horizontally or diagonally).

Two players make actions one by one (placing cross or nought in any free cell on a board). The player who creates such sequence first wins the game.

How to run?

Backend written in kotlin with java 11. Probably can be build and run on highest java versions. Frontend written with Angular 13.

There are two game modes: console and web.

  1. Console mode. It developed mostly for local testing, so more mistakes can be found.
    1. Enter root directory cd tic-tac-toe
    2. Build whole application mvnw clean package
    3. Run console app
    cd tic-tac-toe-console/target
java -jar tic-tac-toe-console-0.1.0-jar-with-dependencies.jar
    1. Enjoy the game! Be careful setting the high difficulty level. It can be slow.
  2. Web mode.
    1. Enter root directory cd tic-tac-toe
    2. Build whole application mvnw clean package
    3. Start ui 
      cd tic-tac-toe-frontend
ng serve --open
    4. Start backend api 
      cd tic-tac-toe-web/target
java -jar tic-tac-toe-web-0.1.0-jar-with-dependencies.jar
    5. Enjoy the game! To make it more interesting you can add obstacles on a board by selecting obstacles checkbox on ui.

AI algorithm

The AI is created with minimax algorithm and alpha-beta pruning.

A bit about repository structure.

Repository contains multiple modules where main module with all game logic is tic-tac-toe-core.

tic-tac-toe-console and tic-tac-toe-web can be considered as different clients for core module which allow to play through different interfaces.

tic-tac-toe-frontend contains web ui written with Angular.

tic-tac-toe-repository is a development for future to allow play the game with another person.
