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: 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. Will you be the last one standing? GAME MODES • Solo: Train your timing and chase your personal best. • NEW – Career: 50 levels in 5 chapters, up to 3 stars each. After the warm-up come Quick Glance, distractions, ghosts, wind and snow – every new star earns Sparks. • NEW – TV party: one iPhone or iPad shows the target and the ranking on the TV via AirPlay, every other phone becomes a buzzer. • Classic: 2 to 8 players on one device – take turns, pass the phone, done. • NEW – Party mode: Every turn brings a house rule – weaker hand, eyes closed, on one leg … • Knockout: Whoever is furthest off each round is out. • Time Guess: A counter starts visibly and vanishes after one second.

About

SpinStrike Balls

One tap. One ring. One shot at your best score. A dot races around a ring. Tap the instant it crosses the glowing zone. Hit it and the dot reverses, speeds up, and the zone shrinks. Miss, and it is over. Then you tap once and go again, because you know the next run is the one. SpinStrike is built for the thirty-second window: waiting in line, between meetings, or that one more try that turns into twenty. HOW IT PLAYS - Tap when the dot is inside the glowing zone - Every hit flips the direction and pushes the speed higher - The zone gets narrower the better you do - Land a dead-center hit for a PERFECT and a bonus +2 - One miss ends the run, with an instant restart every time WHY YOU WILL KEEP PLAYING - Pick-up-and-play in one second, no tutorial, no setup - A skill ceiling worth chasing: anyone can score 10, very few reach 50 - Crisp haptics and sound on every hit and near miss - The color theme shifts as you climb, so a long run looks different from a short one - Your best score is always one tap away from being beaten NO NONSENSE - Plays fully offline - No account, no login, no sign-up - One-time Remove Ads option if you want a clean screen - Simple, focused, and respectful of your time Tap. Miss. Tap again. Beat your best.
