Detail Description

1. Abstract

The Digit Hunt Game is a web-based interactive game developed using React.js, inspired by the popular Wordle game. Instead of guessing words, players are required to guess a five-digit number within a limited number of attempts.

The application provides real-time feedback using color indicators to guide the player. If a digit is correct and in the correct position, it is marked green. If the digit exists but is in the wrong position, it is marked yellow. If the digit does not exist in the solution, it is marked gray.

The project utilizes React hooks for state management and a JSON server to store and retrieve possible solutions. This project demonstrates how React can be used to build dynamic and interactive gaming applications with real-time user feedback.

2. Objectives

The main objectives of this project are:

To develop an interactive number guessing game using React.js.
To understand and implement React hooks for state management.
To simulate Wordle-like game logic using numbers.
To provide visual feedback using color indicators.
To manage game state including guesses, turns, and keypad status.
To use JSON server for storing and fetching solution data.
To build a responsive and engaging user interface.

3. Existing System

Existing systems similar to this project include:

• Wordle (word guessing game)

• Online puzzle and number guessing games

• Basic browser-based logic games

Limitations of Existing Systems

Most games focus on words rather than numbers.
Limited customization for learning purposes.
Do not expose internal logic for educational use.
Less flexibility to modify gameplay rules.
Not ideal for understanding React-based implementations.

4. Proposed System

The proposed system is a Digit Hunt Game where users guess a five-digit number within a fixed number of attempts.

Key Features:

• User inputs a five-digit number using keyboard

• Real-time feedback using colors:

🟩 Green → Correct digit and correct position
🟨 Yellow → Digit exists but wrong position
⬜ Gray → Digit does not exist
• Maximum of 5–6 attempts
• Dynamic keypad color updates
• Win/lose modal display
• Random solution generation using JSON server

This system provides a fun and interactive way to understand game logic and React state management.

5. Implementation Procedure

Step 1: Project Setup

• Create a new project folder (digit-hunt)

• Initialize React project using Vite

• Install dependencies

Step 2: Dependency Installation

• Install required packages:

Axios (for API requests)
JSON Server (for mock backend)

Step 3: Folder Structure Setup

Inside the project:

• src folder – React components and logic

• data folder – Contains db.json file

Step 4: JSON Server Setup

• Create db.json file

• Store an array of possible solutions

• Each solution is stored as a string

Step 5: UI Design

• Create grid layout for guesses

• Create keypad interface

• Add styling using CSS

Step 6: Game State Management

Track the following data:

• Solution (random 5-digit number)

• Current guess

• Previous guesses

• Number of turns

• Keypad status (color updates)

Step 7: Game Logic Implementation

• Compare user input with solution

• Assign colors based on correctness

• Update guesses array

• Update keypad colors dynamically

Step 8: User Interaction

• Capture keyboard input

• Submit guess on Enter key

• Validate input length

Step 9: Result Display

• Show success message on correct guess

• Display modal with number of attempts

• Handle game over condition

Step 10: Testing and Execution

• Run React app using npm run dev

• Run JSON server

• Test gameplay and logic

6. Software Requirements

• React.js – Frontend library

• JavaScript – Programming language

• Vite – Build tool

• Axios – API requests

• JSON Server – Mock backend

• HTML & CSS – UI design

• Visual Studio Code – Code editor

7. Hardware Requirements

Minimum Requirements:

• Processor: Intel i3 or higher

• RAM: 4 GB or higher

• Storage: 128 GB or higher

• Laptop or Desktop Computer

• Internet connection (for dependencies)

8. Advantages of the Project

Provides an interactive and engaging game experience.
Helps understand React hooks and state management.
Demonstrates real-time UI updates.
Uses simple backend with JSON server.
Easy to customize and extend.
Useful for learning game logic implementation.
Can be expanded into more complex games.
