Dice tips
The "d" notation is the universal language of tabletop games: "d20" means a 20-sided die, "3d6" means three six-sided dice added together. The d20 is the workhorse of games like Dungeons & Dragons, where a natural 20 is a critical success and a natural 1 is a critical fail. Percentile rolls use a d100 (or two d10s) for 1–100 results. Rolling multiple dice? The total shown here is the sum, with each individual die listed in the history so you can verify nothing funny happened. Fairness matters, so this roller uses your browser's cryptographic random number generator — the same source of randomness used for security-sensitive operations — not the weaker Math.random() most toy rollers use. It is as fair as physical dice, minus the one that always rolls under the couch. The coin flip is a true 50/50, perfect for settling debates, picking who goes first, or making delightfully arbitrary life choices.
Frequently asked questions
Is the dice roller truly random?
Yes. It uses the Web Crypto API's random number generator, which is cryptographically strong — far fairer than basic pseudo-random functions.
What does "d20" mean?
Standard dice notation: "d" followed by the number of sides. A d20 has 20 sides (results 1–20); "2d6" means roll two 6-sided dice and add them.
Is the coin flip 50/50?
Yes — heads and tails each have exactly a 50% chance on every flip, independent of previous results.
Can I roll more than 10 dice?
The roller caps at 10 dice per roll to keep results readable. Roll again for more — the history keeps your last 10 rolls.
