Random timer
Set a minimum and maximum duration; the tool will pick a random time within that range for the countdown.
How the random timer works
Set a range of minutes (minimum and maximum) and press 'Roll duration'. The tool picks a random number of seconds within that range, with equal probability for every value.
Once a duration is rolled, it's shown on screen and you can start the countdown just like on the regular timer.
A random timer is useful when you don't want anyone to know in advance when time will run out. Because the duration is drawn between the minimum and maximum you set, neither you nor anyone else can predict the end.
Common uses: games like hot potato or musical chairs, speaking turns without a fixed length, surprise rests during a workout and quick reaction drills in class. The wider the range, the less predictable it is.
Worked example
If you set a range of 1 to 10 minutes, the tool might roll, say, 4 minutes 12 seconds, and that becomes the countdown time.
Frequently asked questions
- Can I roll again if I don't like the result?
- Yes, press 'Pick another duration' to discard the result and roll again.
- What's a random-duration timer useful for?
- It's handy for games, group activities, surprise-element workouts, or avoiding knowing exactly how long a wait will be.
- What happens if I set the minimum higher than the maximum?
- The tool shows a warning and won't roll any duration until you fix the range.
- Is the result really random?
- Every second within the range has the same chance of being picked. Everything is calculated in your browser.
- How do I use it in a group game?
- Set, for example, between 30 seconds and 2 minutes, press the draw button, start the countdown and cover the screen: whoever is holding the object when the alarm sounds loses.
