About the Dice Roller converter
A dice roller is only worth using if the dice are fair and the awkward rolls are easy to ask for. Both are the point here.
Tap a die, choose how many, and roll — all at once, or one at a time if you would rather watch them land.
Notation, including the useful parts
Plain forms work as you would expect: `2d6`, `1d20+5`, `3d8-2`. The buttons and the notation box stay in step, so you can use whichever is quicker.
The part most rollers leave out is keeping and dropping. `4d6kh3` rolls four dice and keeps the best three, which is how character stats are rolled. `2d20kh1` is advantage and `2d20kl1` is disadvantage. `dl1` and `dh1` drop the lowest or highest instead.
Dropped dice are shown, not hidden
When a keep rule applies, the dice that did not count are still displayed, struck through and dimmed. Seeing the 2 you dropped is half the fun of rolling four dice for a stat.
Ties drop consistently rather than arbitrarily, so four identical dice with keep-three drop exactly one.
One at a time
Rolling a big handful all at once is fine for a total, but sometimes you want to see them arrive. The one-at-a-time mode reveals each die in turn, with the running total building as they land.
The whole result is worked out before the first die appears, so the reveal is presentation only — the total can never disagree with the dice on screen.
Frequently asked questions
Is it actually random?
Yes, and more carefully than most. The numbers come from your browser’s cryptographic random source, and reducing them to a range uses rejection sampling rather than a plain remainder — a remainder makes the low values very slightly more likely, which is exactly the flaw a random picker should not have.
What does 4d6kh3 mean?
Roll four six-sided dice, keep the highest three and add them. It is the standard way of rolling a character stat, and it gives a much better spread than 3d6 alone.
How do I roll with advantage?
Use 2d20kh1 — two twenty-sided dice, keep the higher. There is a button for it. Disadvantage is 2d20kl1.
Can I roll a d3 or a d7?
Yes. Any number of sides from 2 to 1000 works, whether or not a die of that shape exists — d3 and d7 are commonly simulated at the table anyway.
Does anything leave my device?
No. There is no account and no server involved, so your list is not stored anywhere but your own browser. It also means the page keeps working with the network off.
