STOP! But please right at 6.7 seconds. Buzzer Knockout is the party game that puts your sense of time to the test. One target time, one buzzer, no visible timer – and only the closest one wins. Sounds easy? Try it. HOW IT WORKS Every round comes with a target time – sometimes 3.2 seconds, sometimes 14.8. You hit the buzzer, count in your head, and hit it again when you think the time is up. Whoever's closest wins. Whoever's completely off still has a laugh. GAME MODES - Solo: train your timing and chase your best deviation - Classic: 2–8 players on one device, pass and play - Knockout: the worst guess each round is out – nerves of steel required - Time Guess: a counter starts, vanishes – and everyone guesses to the hundredth of a second how long it ran PLAY ONLINE - Quick match against players worldwide - Private rooms with a 6-digit code for your crew - Synchronized rounds – everyone buzzes in the same match - Game Center leaderboard and achievements MORE THAN A BUZZER - Earn Sparks every round and spend them in the shop - Buzzer Pass: 30 tiers of seasonal rewards - Daily quests for bonus Sparks - Cosmetics: buzzer skins, themes, name effects, frames, win animations, confetti and sound packs - Dozens of achievements – from your first game to the perfect round PERFECT FOR - Apartment nights that are slowly dying - Waiting at the airport - Family gatherings without a small-talk emergency plan - Anyone who claims they have "a great sense of time" SOUNDS SIMPLE – IT ISN'T Try counting 9.3 seconds in your head while your best friend stands next to you mumbling "one, two, three..." to sabotage you. That's exactly the fun. NO ACCOUNT NEEDED No registration, no Wi-Fi for local play – open the app, add players, go. Online play uses Game Center, so there's no extra sign-up.
