Random Number Generator
Its the core of all randomness. Pick a number or generate a whole sequence of numbers within a minimum and maximum value (inclusive) while including or suppress duplicates. Your device is used to quickly generate these numbers, completely random and unique to you every time.
Change the quantity to one if you just want it to pick a number.
You can switch the presentation to roll some dice instead. Or change gears completely with the phone number generator or random letter generator.
