CAPTCHA-Style Matching Game (MATLAB)

An interactive GUI-based game built in MATLAB that challenges users to identify objects matching a given category. Inspired by CAPTCHA-style visual selection tasks, the game dynamically updates graphics and game state based on user input.

Overview

The game displays a matrix of objects (e.g., Dog, Apple, Summer). A prompt instructs the user to select all objects belonging to a specific category (such as “Select all fruits”). Correct selections disappear from the grid, and the game continues until all valid objects have been cleared.

Features

• Dynamic grid-based graphics rendering
• Category-based object matching logic
• Real-time visual updates based on user input
• Difficulty scaling via grid size and object count
• Event-driven callbacks for user interaction

How It Works

• The game initializes a matrix populated with randomly selected objects from multiple categories.
• A prompt displays the target category for the current round.
• User selections trigger callback functions that:
  • Validate the selected object against the target category
  • Update the game state
  • Remove correctly matched objects from the grid
  • Redraw the GUI in real time
• The round ends when the matrix is empty, signaling successful completion.

Technologies Used

• MATLAB
• Matrix-based data structures
• Event-driven programming
• Custom graphics rendering
