How it works:

1. Synchronous Countdown: 3, 2, 1 … At zero, the letter and category appear simultaneously on everyone's screen.
2. Fastest Finger Wins: Smash the buzzer before your opponents thanks to millisecond-accurate sync.
3. Buzz it, Say it: You have exactly 4 seconds to call out your answer aloud to the room (no typing – your spoken word counts!).
4. Community Voting: Fellow players vote with thumbs up or down. Reach at least 50% approval to level up.

NEW: "Steal the Answer" Mode (3+ Players)

Smash the buzzer too early and draw a blank? The round isn't over yet:
• 3-Second Grace Window: The first buzzer has 6 seconds. When the last 3 seconds begin, opponents unlock a pulsing Steal button.
• Seize the Moment: The quickest opponent to steal gets 3 seconds to shout their own answer.
• Impartial Jury: Both dueling players are locked out of voting while neutral peers decide (First Buzzer, Stealer, or both wrong). In a tie, the daring stealer wins!

The Level-Up Thrill (Level 1 to 10):

The better you play, the faster the clock ticks. Start comfortably with a 20-second window at Level 1 — and battle your way up to the intense blitz mode with just 2 seconds at Level 9. First player to reach Level 10 takes the crown!

Highlights:

• 12 Customizable Categories: Tailor your game with 3 or more categories (City, Country, River/Water, Animal, Profession, Plant, Food & Drink, Object, Brand & Company, Celebrity, Movie, TV Series).
• 100% Fair Play Buzzer: Millisecond-accurate reaction timing displayed live (e.g., 542 ms, runner-up +48 ms). Local timestamp capture and host arbitration eliminate network latency advantages.
• Quiz-Power Barometer & Anti-Spam: Premature taps during countdown drain your quiz power and incur start-delay penalties. Smart rate-limiting exponentially locks out aggressive screen-hammering — true fair play for all!
• "Steal the Answer" Dynamic: High-stakes battles even after the first buzz — steal the round and duel for the level.
• Realtime Multiplayer: Play with up to 10 players via room code or instant QR code scan. Supports b
