General improvements/feedback welcomed. 182 reviews 10K+ Downloads Everyone info Install About this game arrowforward Ultimate Tic-Tac-Toe takes the classic game of Tic-Tac-Toe and adds a strategic layer to it.Edge Cases- Again, everything works, but I can't help but think there's something I've not encompassed in the code.I tried a lot of new things here and am curious which are good and which are far removed from such. I'll definitely be refactoring most of this in the future, maybe going the MVC route. X moves first and can go into any of the tile in the grid. We’ll call this the master board and each small game a tile. If a move is played so that it is to win a local board by the rules of normal tic-tac-toe, then the entire local board is marked as a victory for the player in the global board. Kindly suggest what changes I should make, or where I am going wrong.My attempt at this challenge., incorporating lessons from this question, which turned out into a much bigger project than I anticipated, but it works. Ultimate Tic-Tac-Toe has a 3x3 grid of regular tic-tac-toe games. O can then play in any one of the nine available spots in that local board, each move sending X to a different local board. The expected result is to get the best move but instead, it runs endlessly. If(get_game_status(state, player) and player =1) :Įlif(get_game_status(state, player) and player = 2): If in win_state:Įlif in win_state:Īnd the scoring is handled using evaluate function: def evaluate(state, player): To know whether someone has WON || LOSS || DRAW, get_game_status function is called inside minimax function: def get_game_status(state, player): The representation determines or constrains how efficient any operations on the board can be implemented. Pseudo_states = successors(state, player, last_move)Įval = minimax(state, index, opponent(player), depth-1, alpha, beta)Įval = minimax(state, index, opponent(player), depth - 1, alpha, beta) If depth <= 0 or get_game_status(state, player) != 0: Possible_states.append(get_possible_state(copied_board, user_move, idx, player))įinally, every possible move is fed to minimax function which returns a val of the best move: def minimax(state, last_move, player, depth, alpha, beta): The successors function returns the possible states where it can play its move: def successors(boards, player, user_move): Val = minimax(state, index, opponent(player), depth-1, alpha, beta) Pseudo_states = successors(state, player, user_move) # return suboptimal(state, user_move, player) # if suboptimal(state, user_move, player) != 0: The make_bot_move function takes the position of the human and figures out in which sub-board it should play its best_move: def make_bot_move(state, user_move, player, depth): For example, if X played in the top right square of their local board, then O needs to play next in the local board at the top right of the global board. This move 'sends' their opponent to its relative location. # choose a move to playĮnd_move = make_bot_move(boards_list, user_move, player, depth) The game starts with X playing wherever they want in any of the 81 empty spots.

Initailly, once the game is started, the user is prompted to make a move from 1-9 which is then fed to the function:īoards is a list of list which contains the state of each sub-board. All i need is the best value and once i get that, i can retrieve the index from that state. The communication with the board is already handled.

The problem is that when i run the code and it is the time for bot to play its move, it runs endlessly without coming to a conclusion and returning a best_move. Ultimate Tic-Tac-Toe is the ultimate update to the beloved classic game we all love. I am using minimax algorithm with alpha-beta pruning to find out the best move for the bot to play. I am trying to make an ultimate tic-tac-toe game in python which is a little different than the actual one in a way that this game ends when there is a win in any one sub-board.
