Random Number 1-1000
When ten options isn't enough and a hundred still feels small, this is the big-range picker: 1 to 1000, every number at exactly one-in-a-thousand odds.
About the 1 to 1000 Range
A thousand options is raffle scale. It's the range where individual numbers become genuinely rare — hitting any specific number is a 0.1% event — which makes it right for large drawings, sampling, and games built on long odds. It's also big enough to demonstrate how randomness clusters: in a few dozen draws you'll see surprising near-repeats alongside huge untouched gaps.
