How to use the bomb timer
- Type a time, like 30s or 2m, or tap a preset.
- Choose Bomb or Rocket. Tick Quiet ending for a soft bell instead of a boom.
- Press Start, or the space bar. The fuse burns down as time runs out.
- At zero the bomb goes boom, or the rocket lifts off.
Questions
What is a bomb timer good for?
Quick classroom games, quiz rounds, "beat the clock" tidy-ups, and pass-the-bomb word games. The burning fuse shows how much time is left at a glance, and the boom makes the end of a round fun.
Is there a version without a bomb?
Yes. Choose Rocket. The rocket's flame grows over the last 10 seconds and it lifts off at zero. Some schools prefer it, and it's just as exciting.
How loud is the boom?
It's a soft cartoon boom made by your browser, not a recording. Tick Quiet ending for a gentle bell and a "Time's up" instead, or turn off Sound.
Does it flash?
The spark on the fuse flickers about twice a second, and the boom pops once. If your device asks for less motion, the spark stays still and nothing shakes or pops.
What keyboard shortcuts are there?
Space starts and pauses, R resets, F goes full screen, M turns sound on or off, and + and − add or take off a minute.
Is anything sent to a server?
No. The timer runs in your browser. Your theme and sound choices are remembered on this device only.
