3 Dedicated Difficulty Categories (From Title Screen)

Kids & Beginners Easy Mode (206 Questions): Specifically crafted for young kids (ages 5–10) and casual players. Covers fun, intuitive topics: animal sounds, colors, shapes, counting, everyday objects, and the 5 senses.
Medium Mode (376 Questions): Balanced general knowledge, science discoveries, world geography, history, pop culture, and sports for teens and adults.
Hard Mode (149 Questions): Challenging, brain-twisting trivia questions designed to test true trivia champions.

Instant 4-Language Multilingual Engine

Instant real-time switching between English, Hindi (हिंदी), French (Français), and Russian (Русский) via a crisp dropdown menu.
All UI elements, rules, shop items, modal dialogs, and every single question and 4 choices are 100% localized natively.
Fair-Play Guarantee: All non-English options are completely clean and uniform with zero bracket clues or formatting bias, making guessing by formatting impossible!

3 Tactical Lifelines & Game Show Atmosphere

✂️ 50:50 Lifeline: Instantly eliminates two wrong answers, leaving only the correct choice and one distractor.
Flip Question: Discards a tricky question and instantly swaps it with a fresh question from the exact same difficulty tier.
Audience Poll: Opens an interactive live bar chart displaying simulated audience percentage voting breakdown.

️ In-Game Coin Economy, Perks & Themes Emporium

Recharge Dead Lifelines: Spend coins in the shop to re-arm consumed lifelines mid-game.

⚡ Ultra-Fast Web Audio API Procedural Sound Synthesizer

All audio effects (clicks, tick-tocks, lifelines, coin collection, game over, victory fanfare) are synthesized in real-time using the native HTML5 Web Audio API.
Zero audio loading lag: No heavy MP3/OGG sound files to load. Starts playing instantly across mobile iOS Safari and Android Chrome!
