About the Dice Roller
Tezmy's Dice Roller replaces lost dice in seconds. Choose how many dice to roll (1 to 10) and what kind: the classic six-sided die or d4, d8, d10, d12, d20 and d100 for tabletop role-playing games. Press Roll to see every die and the total, with a list of your recent totals. Switch to Flip a coin for heads or tails with a spinning coin and a running count of heads, tails and your longest streak. Every result comes from your browser's secure random numbers with no bias, so it is as fair as real dice, and nothing is sent to a server.

- Yahtzee and dice poker: five d6.
- Role-playing games: d20 for attacks and checks, d4 to d12 for damage, d100 for percentage tables.
- Classroom maths: roll dice to make sums, practise probability or pick random numbers.
A little probability
With one fair die, every number is equally likely. When you add dice together, middle totals become more common because there are more ways to make them: with two d6, a total of 7 has six combinations while 2 has just one. Roll many times and watch the recent totals: over time they cluster around the middle, which is a nice way to see probability in action.
Tips
- The dice keep your last settings while the page is open, so you can roll again with one tap.
- For a random number in any range (not only dice sizes), use the Random Number Generator.
- For picking a person or option from a list, try Spin the Wheel or the Random Name Picker.
- Coin flips are great for quick decisions: who goes first, which option to choose.

Frequently asked questions
Is this dice roller fair?
Yes. It uses the Web Crypto API, your browser's secure random number source, and a method that removes the tiny bias simple random code can have. Every face of every die has exactly the same chance.
What do d6, d20 and the others mean?
The number after “d” is how many sides the die has. A d6 is a normal cube die numbered 1–6, a d20 has 20 faces and is used in games like Dungeons & Dragons, and a d100 gives a number from 1 to 100, often used for percentages.
How do I roll 2d6?
“2d6” means two six-sided dice added together. Choose 2 dice and d6, then press Roll; the total is shown under the dice. The same works for 3d8, 4d6 and so on, up to 10 dice.
What is the most common total with two dice?
Seven. There are six ways to make 7 with two dice (1+6, 2+5, 3+4 and the reverse), more than any other total, so it comes up about one time in six. Totals of 2 and 12 are the rarest, about one time in 36 each.
Can I flip a coin here too?
Yes. Choose Flip a coin at the top. Each flip is 50/50, and the tool counts heads, tails and your longest run of the same side. There is also a separate page just for flipping a coin.
Can I use it for board games?
Of course: Ludo, Monopoly, Snakes and Ladders, Yahtzee and any game that needs dice. Put your phone or laptop where everyone can see it and take turns pressing Roll.
