Bomb Timer With a Defuse Mode

While more than ten seconds remain the tick fires once per second. After that the gap contracts along a power curve and reaches 85 milliseconds at zero, the way a detonator behaves in tactical shooters. Notes are placed on the audio timeline a quarter of a second ahead, so the rhythm holds even when the tab stutters.

Yes. Time is measured by the page clock rather than by the audio engine, so when you come back you see the real remainder instead of a frozen one. The browser may suspend the sound while you are away — the ticking returns with the tab, and the countdown itself never shifts.

No. The wire colors are random, but which one to cut follows unambiguously from a five-rule defuser manual that sits open right under the wires and never changes between rounds. Rules are checked in order, the first match wins, and the last one always applies, so an answer exists for every possible set of colors.

Open "For streams and parties" and copy the OBS link. It loads the page with no header, menu or settings — just the casing and the display — and starts the countdown itself. Add it to OBS as a Browser source: the background is transparent, and if your build cannot handle transparency, take the green or magenta variant and apply a chroma key.

Yes, that is what the Ticking switch is for: Always, Last 30 s and Off. On a long fuse — ten minutes for a cleanup or a quiz — constant ticking gets in the way, while the final acceleration and the blast stay where they are. Volume has its own slider. The switch works mid-countdown too.

It picks the fuse length at random inside the bounds you set and hides the digits. The cord is measured against the upper bound, so it only shows the latest possible moment and gives nothing away: the bomb goes off somewhere before the cord runs out. That is classic hot potato: the phone goes around the circle and nobody knows who will be holding it. The default bounds are 15 to 45 seconds and you can change them.

Yes: the Sound block has MP3 and WAV buttons. The file is built right in the browser from the same settings you hear on screen — fuse length, tick theme, ticking mode and ending — and runs from the first tick to the last echo of the ending. WAV covers countdowns up to 10 minutes, MP3 up to an hour. In Party mode the file length is picked at random inside your bounds.
