AI Programming: Sudoku Game Development

Human Idea

A Sudoku game involves filling a 9x9 grid with numbers so that each row, each column, and each of the nine 3x3 subgrids (separated by thicker lines) contains all digits from 1 to 9 exactly once, with no repetition within the same row, column, or subgrid.

This time, we used AI programming to develop the Sudoku game, again submitting prototype diagrams and requirement documents for the AI to execute.

Core Features

1. Basic Game

• Standard 9×9 Sudoku board
• Select cells by clicking
• Input numbers via a keypad
• Clear incorrect numbers (by clicking again)

2. Difficulty Levels

• Easy (more given numbers)
• Medium
• Hard (fewer given numbers)

3. Visual Aids

• Highlight selected cell
• Highlight identical numbers
• Mark incorrect numbers in red

4. Game Controls

• New Game
• Hint
• Check for Mistakes
• Show Solution
• Timer

5. Technical Requirements

• Responsive design for mobile and desktop screens
• Support for touch interactions
• Clean and simple interface design
• Interface layout reference: see attached Sudoku Game Prototype Diagram

Deliverable

A single HTML file containing the complete game code, executable directly in a browser.

AI Programming

First, create a new Qoder project, add the Sudoku game prototype diagram to the context, and submit the development requirements to Qoder, then wait for Qoder to complete the code.

Version 1

The first version completed by Qoder:

After testing, the first version met our functional requirements, but the number cells were too small and visually straining, requiring optimization.

Version 2

Submitted the optimization requirements for the second version to Qoder:

Optimizations:
1. The number cells are too small and visually straining. Increase the size of the number cells.
2. Review and check all functional logic.

The second version completed by Qoder:

The second version of the Sudoku game not only has better visuals but is also more robust and reliable in logic! 🎉 💯

Development Summary

This time, we used AI programming to develop the Sudoku game, again utilizing game prototype diagrams and development requirement documents submitted for the AI to execute.

Through two iterations, we completed the Sudoku game development, successfully achieving our development goals.
