There are many standalone Tic Tac Toe apps (APK files) available on third-party app stores. While many are safe, any time you download an APK from an unofficial source, you take a risk. However, this also has no relation to the AIX file we are discussing.
public TicTacToeGame() board = new char[3][3]; currentPlayer = 'X'; reset();
: App Inventor pushes this raw index to a specific path in Firebase (e.g., Rooms/Room_ID/LatestMove ).
: It employs a 2D indexing system where the first number represents the row and the second represents the column .
To maintain cohesion with the io prefix, the aix module likely implements a standard interface, such as MoveEngine . This enforces a contract where the AI receives a BoardState object and returns a Move object, decoupling the UI from the logic.
But what truly sets io.horizon.tictactoe.aix apart is its use of a technique called Monte Carlo Tree Search (MCTS). This algorithm allows the AI to simulate thousands of possible games, evaluating the outcomes of each and using that information to inform its decisions. The result is an AI that is not only highly skilled but also highly adaptable, capable of adjusting its strategy to suit the playing style of its opponents.
The latest updates to the extension have made it more powerful than ever:
: The latest v2.0 update allows you to create online games by integrating with the Firebase Realtime Database .
Since the MIT App Inventor case is most plausible, let’s examine the internals.
If you are an MIT App Inventor user, here is how to integrate this extension into your project:
A major challenge when coding matrix-based games in visual programming languages is coordinate mapping. The extension structures the standard 3x3 play space into a clean, predictable grid layout:
