Random number picker with no repeats Dice roller 1-6
A die that cannot roll off the table
A fair six-sided die gives each face a one in six chance, and so does this page. The pick comes from the cryptographic random generator in your browser, so there is no weighted corner, no rolling bias and no way for anyone to steer a result. It stands in for a lost die in a board game, a quick roll in a math lesson or a tie-breaker.
The page starts with How many at 1 and Keep drawn numbers out of later draws off, which is how one die behaves: the 4 you just rolled can come up again. Rolling two dice takes two changes. Set How many to 2 and switch off No repeats. With that box on, the two numbers are always different, so doubles would be impossible, which is not how real dice work. The page shows the two numbers, and you add them yourself.
The odds of two dice are a good lesson in themselves. There are 36 combinations, and a total of 7 can be made in six ways, so it comes up one time in six. A 2 or a 12 happens only once in 36. Doubles show up once in six rolls. Rolling a few hundred times with the Earlier draws list is an easy way for students to see these numbers appear.

Questions about rolling a die online
Is it as fair as a real die?
Yes, and often fairer. Each of the six numbers has a one in six chance, and past rolls have no effect on the next. A cheap physical die can be slightly uneven, which a random generator is not.
Why does rolling two dice never give doubles?
Because No repeats is switched on, which forces different numbers in a single draw. Clear that box and doubles come back, with a one in six chance on a roll of two.
Does it add up the dice?
No, the page shows each number and you add them. It keeps the dice visible, which matters in games where the single numbers count.
Can I roll a die with more sides?
Change To. Setting it to 20 gives a d20, and 100 gives percentile rolls. Add any modifier yourself after the roll.
What are the chances of rolling a six?
One in six, about 16.7 percent, on each roll. Over many rolls you expect around a sixth of them to be sixes, but short runs vary a lot, and three sixes in a row occur about once in 216 tries.
