Generate one or many random integers within a range, with an optional no-repeats mode.
By default, yes — each number in a batch is generated independently, so repeats are possible. Turn on "No repeated numbers" to sample without replacement instead.
With "No repeated numbers" on, you can't generate more unique values than the range actually contains — e.g. you can't draw 20 unique numbers from a range of 10. The calculator flags this instead of silently repeating values.
The result regenerates automatically whenever you change Min, Max, count, or the no-repeats toggle, so you always see a fresh draw matching your current settings. Use the Reroll button to get a new draw without changing any inputs.
