Stop the timer at exactly 10.00 seconds – without looking. Buzzer Knockout turns the stopwatch challenge into a party game. Everyone sees the same target time, say 6.7 seconds. Hit the buzzer to start an invisible timer and hit it again when you think the time is up. Closest to the target wins. No display, just your sense of timing. NEW IN 1.8 • Quick duel: a real opponent right away – play against the recorded run of a player near your level. • Clubs: up to 30 players compete as a team in the weekly league. • Invite friends: every friend who joins through your link brings you both Sparks. • Career: 70 levels in 7 chapters – now with double stops, a metronome, a vanishing clock and a wandering buzzer. • An Advent calendar in December and your year in review to share. BUZZER ROYALE Every Friday at 8 pm (Berlin time) everyone plays at once. Each round the worse half is out, until only one is left – with a countdown on your lock screen. GAME MODES • Solo and Career: train your timing and collect up to 3 stars per level. • TV party: one iPhone or iPad shows the target and the ranking on the TV via AirPlay, every other phone becomes a buzzer – everyone for themselves, in teams or as hot potato. • Classic: 2 to 8 players on one device – take turns, pass the phone, done. • Party mode: every turn brings a house rule or a random twist. • Knockout: whoever is furthest off each round is out. • Time Guess: a counter vanishes after one second. How long did it run? • 10-Second Challenge, Table Mode and Tournament. • Online: Quick Match and private rooms via code or link – no Game Center account needed. DUEL BY LINK Three rounds, fixed target times: play first, send the link – your friends play the same times whenever they like, even without the app via App Clip or in the browser.
