Roll a Die
For the board game night where the dice went missing under the sofa.
A die when there isn't one
Six slices, one through six, and an even chance of each. It does what the missing die from the board game box did, and it cannot roll off the table or land wedged against a book.
Every roll draws from your browser's cryptographic random number generator rather than the ordinary one, and the result is decided before the animation starts. A slow frame rate cannot nudge it, which is more than can be said for a die rolled onto an uneven table.
Rolling more than one
Two dice are not two spins of a six-slice wheel unless you spin twice - and if you do, the totals behave exactly as a real pair would, with seven coming up six times as often as two. That is worth knowing before assuming any wheel can replace 2d6 in a single spin.
For a straight total, build the wheel you actually want: put the outcomes 2 through 12 on it and weight them 1, 2, 3, 4, 5, 6, 5, 4, 3, 2, 1. That reproduces the real distribution of two dice in one spin, which no amount of spinning a six-sided wheel twice will do faster.
Dice worth building
- d20 for tabletop. Paste 1 to 20 and you have the roll most role-playing games are built around, without hunting for the physical one.
- d4, d8, d10, d12. Any polyhedral die is just a list of numbers. Type the range and the wheel becomes it.
- Advantage and disadvantage. Spin twice and take the higher or lower, exactly as the tabletop rule reads.
For board games and classrooms
A phone on the table settles the missing-die problem for Monopoly, Yahtzee, backgammon or anything else that came in a box missing a piece. Nobody has to trust a roll they did not see, because everybody watches the same screen.
In a classroom the same wheel does probability teaching without a bag of dice. Turn Count on and roll fifty times: the tally shows the distribution flattening toward even, which is a more convincing demonstration of the law of large numbers than a diagram.
Why a wheel and not a dice roller
A dice-roller app gives you a number. A wheel shows you the draw happening, which matters when more than one person needs to accept the result. The spin is the evidence.
It is also editable in a way a dice app is not. If your game needs a die numbered 0 to 5, or one with two sixes, or one with words instead of numbers, you type it in and the wheel becomes that.

Questions
Dice Roll Wheel FAQ
Is the dice roll actually random?
Yes. Each roll uses crypto.getRandomValues(), the cryptographic generator browsers provide for security tokens, not the ordinary Math.random(). Integers are drawn by rejection sampling, which avoids the small bias a plain modulus introduces.
Can I roll two dice at once?
Spin twice for two independent rolls. For a single spin that gives a two-dice total, put 2 through 12 on the wheel and weight them 1, 2, 3, 4, 5, 6, 5, 4, 3, 2, 1 - that reproduces the real distribution, where seven is six times more likely than two.
Can I make a d20 or other polyhedral dice?
Yes. Any die is just a list of numbers: paste 1 to 20 for a d20, 1 to 12 for a d12, and so on. The wheel rebuilds as you type.
Can I keep a tally of rolls?
Yes. Turn on Count in Settings and the Results tab records how many times each number has come up, which is useful for teaching probability or checking a run of luck.
Does it work offline?
After the first load, yes. Every roll is computed in your browser, so no connection is needed once the page is open.
