Frequently Asked Questions About Random Number Generator
How do I generate a random number between 1 and 100?
Open the Number tab, set Minimum to 1 and Maximum to 100, then click Generate. You'll get a random number between 1 and 100 instantly. You can change the range to any values like 1-10, 1-1000, or even negative numbers.
Can I generate multiple random numbers at once?
Yes. Set the Count field to however many numbers you need (up to 1000). You can also check 'Unique only' to prevent duplicate numbers and 'Sort results' to get them in ascending order.
How do I generate random numbers with no repeats?
Check the 'Unique only' checkbox in the Number tab. This ensures every generated number is different. Note: the range must be large enough to accommodate the count (e.g. you can't generate 20 unique numbers from a 1-10 range).
Can I use this as a lottery number generator?
Yes. Set your range (e.g. 1-49 for many lotteries), set the count to the number of balls drawn (e.g. 6), check 'Unique only' and 'Sort results', then click Generate. You'll get a set of non-repeating lottery numbers.
How does the dice roller work?
Select 1 to 6 dice in the Dice tab and click Roll. Each die shows an animated result from 1-6 with traditional dot patterns. For multiple dice, you'll see each individual roll plus the total sum.
Is the coin flip fair — 50/50 chance?
Yes, each flip has an equal 50% chance of Heads or Tails. The tool also tracks your running totals so you can see the distribution over multiple flips.
How do I pick a random name or item from a list?
Go to the List tab, type or paste your items (one per line) — names, options, foods, tasks, anything. Set how many to pick, then click Pick Random. Great for choosing who goes first, picking a restaurant, or making group decisions.
Can I use this as a random team generator?
Yes. Enter all participant names in the List tab (one per line). Set Pick Count to the number of people per team. Click Pick Random multiple times, removing picked names each round, to form random teams.
What is the random color generator for?
The Color tab generates a random hex color with its RGB value, displayed as a visual swatch. Designers use it for inspiration, color palette generation, or picking accent colors. Click the hex code to copy it for use in CSS, design tools, or anywhere else.
Are the numbers truly random?
The tool uses JavaScript's Math.random(), which provides high-quality pseudo-random numbers suitable for games, decisions, raffles, classroom activities, and everyday use. For cryptographic or security purposes, use a dedicated cryptographic random generator.
Does this tool work offline?
