Name your buttons cleanly (e.g., Btn_11 , Btn_12 , Btn_13 up to Btn_33 ) to easily match the row-and-column index logic. Step 3: Map the Visual Blocks

Rather than forcing developers to build coordinate systems using multi-dimensional lists, the extension manages data tracking internally. Key highlights of this extension include:

Call the "Check Winner" function to trigger an event (e.g., a "Game Over" popup). Enhancing with AI

Set the difficulty level (e.g., Easy, Medium, Impossible) or AI personality.

4.2 Primary Operations (API)

: Built-in logic automatically tracks alternating player moves, preventing a user from overriding an already occupied square.

: Toggles a built-in algorithmic opponent and adjusts the difficulty settings for single-player modes.

The AI assumes the human will try to minimize the AI's score.

: Place an empty VerticalArrangement or TableArrangement component onto your visible canvas screen. This will act as the dynamic host container where the extension injects the interactive 3x3 game board. io.horizon.tictactoe.aix

: In your App Inventor project, go to the "Extension" palette, click "Import extension," and upload the file.

"board": ["X","O","","","X","","","","O"], "currentPlayer": "O", "history":["player":"X","pos":0,"player":"O","pos":1,...], "outcome":"ONGOING"

Below is a comprehensive article exploring the concepts, applications, and potential implementation of such a component.

Instead of constructing dozens of conditional mathematical logic checks to scan rows, columns, and diagonals for matching characters, the extension runs these processes silently in the background. It instantly triggers built-in events like X_Won , O_Won , or Game_Tied . How to Implement the Extension in Your Project Name your buttons cleanly (e

In a significant move, Horizon later announced, "Great news! The Tic Tac Toe extension is now open source!". The complete source code is now available on GitHub, which is a massive benefit for the community. Open-sourcing the code provides several key advantages:

Introduction Tic-Tac-Toe (noughts and crosses) is a well-known, finite, zero-sum, perfect-information game that serves as a compact domain for illustrating algorithms in search, reinforcement learning, game theory, and human–AI interaction. io.horizon.tictactoe.aix (hereafter “the module”) is conceived as a reusable software artifact that encapsulates game rules, state representation, move validation, pluggable AI agents, and interactive interfaces suitable for both educational use and lightweight research experiments.

: It uses a row-column system (e.g., 11 for row 1, col 1) and automatically manages move validation to prevent players from overriding existing marks. Enhancing with AI Set the difficulty level (e
