Sized Up vs Buzzer Knockout

Test your perception and challenge your friends in the ultimate guessing game where size truly matters—how well can you judge the real dimensions of simple objects?

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.
