About

BUZZ Math Challenge

Features
Read full description

BUZZ is the fastest maths reflex game on your phone. One rule, zero mercy: when the number on screen is a multiple of 3 or ends in 7, say "BUZZ" out loud or tap the giant button. Any other number? Stay silent and let it pass. Every round is quicker than the last. You start with 2.7 seconds and end up with barely 1.1. Blink and it's over. WHY YOU'LL KEEP COMING BACK • Voice control: shout BUZZ and the game hears you. No hands needed. • Tap fallback: the button and the number itself are both targets. • Streaks: five in a row doubles your points, ten in a row triples them. • Celebrations: confetti, "ON FIRE" and "UNSTOPPABLE" banners, live NEW RECORD alerts. • Learn as you play: every correct buzz shows you why (27 = 3 × 9). • Lifetime stats: games played, best round, best streak, total buzzes. • Second chance: watch a short ad once per run to keep your score going. • Calm mode: turn off screen shake and flashes in Settings. Quick to learn, brutal to master. Perfect for a bus ride, a classroom warm-up or a shout-off with friends. BUZZ listens through Apple's Speech framework only while a round is running, to detect the word "Buzz". The app stores no audio. You can always play by tapping instead.
