The "d" in d4, d6, d20 (and so on) just means "die with that many sides." A d6 is the classic 6-sided cube you find in Monopoly. A d20 is a 20-sided gem-shaped die used in Dungeons & Dragons. When you see notation like 2d6, it means "roll two 6-sided dice and add the results together."
To use this roller: pick your die type, use the + and − buttons to set how many dice to throw at once, then press Roll (or hit Enter). Each die appears on screen — the d6 shows actual pips like a real die, while the other shapes (triangle for d4, diamond for d8, pentagon for d12, and so on) display the rolled number inside. If you roll more than one die, the total is shown below.
The session stats bar at the bottom of the card tracks how many times you've rolled, your running total, and your highest and lowest result — handy if you're keeping score or testing probability over many rolls.
Quick reference: what each die is used for
d4 — damage for daggers and magic missiles in D&D; the pointy pyramid-shaped die
d6 — the everyday board-game die; used in Monopoly, Catan, Yahtzee, and countless others
d8 — longsword and battleaxe damage in D&D; looks like two pyramids glued together
d10 — hit die for fighters; two d10s together can make a d100 (percentile roll)
d12 — greataxe damage; hit die for barbarians; the least-used die in most RPG sets
d20 — the iconic RPG die; used for attack rolls, skill checks, and saving throws in D&D
Custom — enter any number from 2 to 100; useful for d3, d100, or homebrew mechanics

Running a campaign? Grammarly keeps your session notes, lore documents, and homebrew rules polished and easy to read — right inside Google Docs or Word.
You can roll a d4, d6, d8, d10, d12, d20, or a custom die with any number of sides from 2 to 100. This covers the standard 7-die polyhedral set used in Dungeons & Dragons, Pathfinder, and most other tabletop RPGs. Need a d3? Use the Custom option and enter 3 sides.
Can I roll multiple dice at the same time?
Yes. Use the + and − buttons to set a quantity from 1 to 20. The result shows each die individually and sums them — useful for 2d6 movement, 4d6 drop-lowest character stats, or any multi-die damage roll. The total is displayed prominently so you don't have to add in your head.
Is the dice roller truly random?
Yes. Every roll uses crypto.getRandomValues() — the browser's cryptographically secure random number generator. It produces numbers with no predictable pattern or bias, making it statistically fairer than a physical die that can be worn or weighted over time.
How do I roll a percentile (d100)?
Click Custom, type 100 in the sides box, and press Roll. You'll get a result from 1 to 100. Alternatively, some games use two d10s — roll 2d10 and read the tens digit from one and the units from the other (treating 00 as 100). For a straight 1–100 result, the Custom 100-sided option is simpler.
Can I see my previous rolls?
Yes. The history panel below the dice shows your last 20 roll events in order, newest first. Each entry shows the die type, individual results, and total. Use Clear History to wipe it when you start a new game or session.
