Bomb timer
A dramatic countdown for games and classrooms: red LED digits, ticking beeps, faster in the last 10 seconds, then a cartoon BOOM.
Space starts and pauses, R resets. Just for fun: the BOOM is a cartoon sound and a shake of the screen.
Questions people ask
What is a bomb timer?
A countdown timer styled like a movie time bomb: red LED digits, a beep every second that speeds up in the last ten seconds, and a cartoon BOOM at zero. It's popular for classroom games, party games, escape rooms and quick challenges.
Is it loud?
The beeps are short and the BOOM is a soft rumble. Tick Mute to run it silently, with just the flashing display.
Can I set any time?
Yes, any number of minutes and seconds. The buttons give quick presets from 10 seconds to 10 minutes.
Does it keep running in the background?
It keeps exact time, but browsers slow down animation in hidden tabs, so keep the tab open on screen for the beeps.
