FAQ

Does it keep running in the background?

It keeps time from the clock, so it stays accurate, but some phones pause pages in the background — keep the screen on during a game.

Can anyone see how long it’ll run?

Not while “Hide the countdown” is on. The length is shown only when time’s up.

Is it really random?

Yes. Values come from your browser’s cryptographic random source, and every possible value has the same chance.
