One Tool for Numbers, Dice and Coins
Whether you're picking a raffle winner, settling a decision, running a board-game night, or teaching probability, this random number generator has you covered. It combines three of the most-used randomisers — a number generator, a dice roller, and a coin flipper — into a single fast, private tool that runs entirely in your browser. No ads interrupt the draw, nothing is stored, and every result is one tap away from your clipboard.
Mode 1: Random Numbers
Set a minimum and maximum, choose how many numbers you want, and press Generate. Two options make this far more useful than a basic generator:
- Unique — guarantees no repeats, so you can draw lottery numbers, assign unique IDs, or pick distinct winners.
- Sort — lists the results in ascending order, which is handy when you need a clean, readable sequence.
Want a single number between 1 and 100 to settle something? Leave the count at 1 and tap Generate. Need 6 unique numbers between 1 and 49 for a lottery line? Set the range, count, and enable Unique.
Mode 2: Dice Roller
The dice mode rolls any standard die — d4, d6, d8, d10, d12, d20, or d100 — and lets you roll several at once. Each individual roll is shown along with the total, which is exactly what tabletop and role-playing games such as Dungeons & Dragons need. Rolling 2d6 for a board game or 4d6 for character stats takes a single tap, with no physical dice to lose under the sofa.
Mode 3: Coin Flip
Sometimes a yes/no answer is all you need. The coin mode flips one or many coins and reports the Heads/Tails split. Flipping 100 coins at once is also a neat way to demonstrate probability — over many flips, the ratio drifts toward 50/50, illustrating the law of large numbers for students and teachers.
Common Uses
- Giveaways and raffles — draw unique winning numbers fairly and transparently.
- Classroom maths — demonstrate randomness, probability, and statistics live.
- Games — replace lost dice or settle whose turn it is.
- Decision-making — let a coin flip or a random pick break a deadlock.
- Sampling — select random rows, names, or items from a numbered list.
A Note on Fairness for Giveaways
If you're using random numbers to pick contest or giveaway winners, two small habits keep things transparent. First, decide and announce the range and rules before you draw — for example, "entries are numbered 1 to 250, drawing 3 unique winners." Second, draw all winners in a single Unique generation rather than one at a time, so no number can be repeated and the process is visibly fair. Keeping a screenshot of the result is a simple way to show participants the draw was honest.
Fair, Fast and Private
Because all randomisation happens locally in your browser, results appear instantly and nothing you generate is sent anywhere. Press Generate as many times as you like — each draw is independent of the last.
