Free random tools for everyday decisions

Whether you need a random number for a raffle, dice for a board game, a strong password for a new account, a quick coin toss to settle an argument, fair teams for PE or five-a-side, or a wheel to pick who goes first, everything you need is on this one page. Every tool is 100% free to use, as often as you like – there's nothing to download, no account to create and no limit on how many times you can use them. It works on any phone, tablet or computer.

Random number generator

Choose any range, such as 1 to 10, 1 to 100 or 1 to 1,000, and get an instant random number. Use Increments to pick only certain numbers: an increment of 5 between 0 and 100 can give 0, 5, 10 and so on, and an increment of 0.5 lets you pick half numbers. Both the lowest and highest numbers can be chosen. It's handy for raffles, prize draws, bingo, board games, maths lessons and choosing a random winner.

Password generator

Create a strong random password from 6 to 64 characters, using any mix of capital letters, lowercase letters, numbers and symbols. Or switch to Words mode for a passphrase made of random words joined by numbers or symbols, which is easier to remember and still hard to crack. Passwords are made on your device and never sent anywhere.

Coin flip

Need to flip a coin but don't have one? Press Flip coin for a fair 50/50 heads or tails result, with a running count of heads and tails so you can do best of three, or best of ten.

Dice roller

Lost the dice for a board game? Roll up to ten virtual dice at once and see the total straight away. Choose a normal six-sided die (D6) or the D4, D8, D10, D12 and D20 dice used in role-playing games like Dungeons & Dragons. Every face has an equal chance of landing.

Random team generator

Add everyone's names, choose how many teams you need and the team picker shuffles them into fair, random groups. It's great for classrooms, sports teams, quiz nights, work groups and games.

Spin the wheel

Our wheel spinner lets you add your own options – names, prizes, places to eat, chores or anything else – and spin to pick one at random. Every option has an equal chance, so it's a fun and fair random name picker.

Frequently asked questions

How do I generate a random number?

Enter the lowest number in From, the highest in To, and how far apart the possible numbers should be in Increments (1 for every whole number). Then press Generate number. Both the From and To numbers can be picked.

Are the results really random?

Yes. Every tool uses your browser's built-in cryptographic random number generator (Web Crypto), the same kind of randomness used for security, rather than the simpler Math.random function. Every possible result has an equal chance.

Is the password generator safe to use?

Passwords are created on your own device and are never sent to or stored on our server. For important accounts use at least 16 characters, or at least 4 words in Words mode.

What is a word password?

A word password, or passphrase, joins several random words with numbers or symbols, such as Maple7Tiger#River2Oasis. Words are picked from a list of 7,772 words, so a 4-word password is strong but much easier to remember than random characters.

How do I split people into random teams?

Type how many teams you want, add each person's name, then press Make random teams. Names are shuffled and shared out as evenly as possible.

Can I add my own options to the wheel?

Yes. Type your options into the list next to the wheel, add or remove as many as you like, then press Spin the wheel. Each option has the same chance of being picked.

How do I roll dice online?

Choose how many dice to roll (1 to 10) and the type of dice, from a normal 6-sided die (D6) to a 20-sided D20, then press Roll dice. You'll see each dice and the total.

Is it free?

Yes. All the tools are completely free, with no sign-up, and they work on phones, tablets and computers.
