Building My Kaun Banega Crorepati (KBC) Web Simulation Game

When I was learning web development, my favorite way to practice was by building interactive simulations of popular TV game shows. One of my largest early projects was a full-fledged web simulation of Kaun Banega Crorepati (KBC) Season 3, the popular Indian version of *Who Wants to Be a Millionaire*, which was famously hosted by Shahrukh Khan at the time. In this post, I am sharing the development details of how I coded this simulation game using pure HTML, CSS, and JavaScript, and how you can run it on your own server.

Designing the KBC Gameplay Logic

To make the simulation feel authentic, I had to replicate the tension and structure of the TV show. The code structure focuses on three core elements:

• The Question Database: I compiled a structured array of 15 question tiers, grading them from easy (worth ₹1,000) to the ultimate jackpot question (worth ₹2 Crore).
• The Lifeline Engine: Implementing the logic for the four classic lifelines: 50:50 (removing two wrong answers), Phone a Friend (simulating a response based on question difficulty), Audience Poll (generating a weighted random distribution favoring the correct answer), and Flip the Question.
• Sound & UI Synchronization: Using timed CSS transitions and audio triggers to mimic the iconic KBC clock ticking and win/lose sound effects.

The Core Javascript Code Structure

As a developer, I focused on writing clean, modular functions to handle the state changes of the game. Here is the general state engine logic I used:

• loadQuestion(index): Fetches the next question from the array, resets the timer, and updates the display board.
• checkAnswer(selectedOption): Compares the player's choice against the correct key. If correct, it plays a success sound and increments the prize level. If incorrect, it triggers the game-over screen.
• triggerLifeline(type): Disables the used lifeline button and runs the corresponding helper script to filter options or show percentage charts.

Reliving the Shahrukh Khan Era (KBC 3)

KBC Season 3 stood out because of the energetic, tech-forward presentation style that Shahrukh Khan brought to the show. In my simulation, I matched the visual design to that specific season's sleek, blue-and-neon UI layout, complete with custom text alerts and quotes matching his dialogue style. It was a fantastic learning exercise that helped me master client-side state management before modern frameworks like React became the standard.

If you are looking to learn web development by building games, I highly recommend starting with retro simulations. Building games teaches you logic, user input handling, and design principles in a way that regular tutorials cannot match.
