To roll a dice online, open the free random number generator, set Lowest to 1 and Highest to 6, and click Generate. That's one fair six-sided die. For two dice, set How many to 2 and keep Allow repeats ticked, because a real pair of dice can land on doubles. Each number has exactly the same chance, so it's a fair stand-in when the dice have gone under the sofa or the board game box came without them.

Roll a dice: one, two or a handful

What you need	Lowest	Highest	How many	Allow repeats
One standard die	1	6	1	either
Two dice (Monopoly, Backgammon, Catan)	1	6	2	ticked
Five dice (Yahtzee-style games)	1	6	5	ticked
A d20 for role-playing games	1	20	1	either
Percentile roll (d100)	1	100	1	either
A coin toss (1 = heads, 2 = tails)	1	2	1	either

The results appear in one line, separated by commas, for example 4, 4. That's a double. The generator doesn't add the dice up for you, so for games that use the total (like Monopoly or Catan), add them in your head: 3, 5 means move 8.

Step by step

1. Open the free random number generator. It starts on Numbers.
2. Type 1 in Lowest and 6 in Highest.
3. Type the number of dice in How many.
4. Leave Allow repeats ticked. If you untick it, the generator can never show the same number twice in one go, which isn't how dice behave: two dice should show a double one time in six.
5. Click Generate for each roll. The settings stay as they are, so the next roll is one click away.

If you'd like the dice listed from lowest to highest, as in Yahtzee where you look for runs, tick Sort from low to high.

Why "Allow repeats" matters

When you roll two real dice, each die doesn't know what the other did. There are 36 equally likely combinations (6 × 6), and 6 of them are doubles: 1-1, 2-2, 3-3, 4-4, 5-5 and 6-6. So doubles come up 1 time in 6.

With Allow repeats off, the tool draws numbers like raffle tickets: once a 4 is picked, it's out. That's perfect for lottery-style draws, but it would quietly remove every double from your game, and change the odds of every total. Keep it on for dice.

Dice totals and their odds

When you roll two dice and add them, the totals aren't equally likely, because some totals can be made in more ways. That's why 7 shows up so often in board games.

Total	Ways to make it	Chance
2 or 12	1	1 in 36 (about 2.8%)
3 or 11	2	1 in 18 (about 5.6%)
4 or 10	3	1 in 12 (about 8.3%)
5 or 9	4	1 in 9 (about 11.1%)
6 or 8	5	5 in 36 (about 13.9%)
7	6	1 in 6 (about 16.7%)

That's also why a single random number from 2 to 12 is not the same as rolling two dice. It would make 2 just as likely as 7. Always roll the dice separately and add them.

Is an online dice fair?

A real die is only as fair as its shape and the surface it lands on. Cheap dice can be slightly uneven, and a throw onto a soft carpet can just slide instead of tumbling. The online roll avoids all that: every number between Lowest and Highest has exactly the same chance, using the secure random source built into your browser, and the tool rejects the small biases that simple code can introduce when it squeezes random numbers into a range. If you're curious how that works, see our explainer on true random vs pseudorandom numbers.

What it can't do is stop the "that roll didn't count" argument. Agree on house rules before the game: one click per turn, and the result on screen stands.

Make it more fun for kids

Some players like to see something spin. Two good options:

• A dice wheel. Open the free wheel spinner, type 1 to 6 on separate lines, and click the wheel. It's one die, with a drumroll. Copy the link and you have a reusable dice wheel.
• Custom dice. Put words on the wheel instead of numbers: colours for a colour-matching game, actions like "jump", "clap" and "spin", or the names of players for who goes first. Our truth or dare wheel shows how far you can take that.

For picking who starts the game, the free random name picker is quicker than rolling for highest.
