Frequently asked questions
Roll up to 20 dice at once, each with anywhere from 2 to 100 sides — so a D6, D20 or any custom die all work.
It makes a roll reproducible: the same seed and settings always give the same result. Change the seed to roll again, or share it so others see your exact roll.
Yes. Set the sides to 20 for a D20, 12 for a D12, and so on. Set the number of dice to roll several at once and read the total.
Each side has an equal chance using a quality pseudo-random algorithm, so rolls are statistically fair for games and decisions.
Same seed, same roll — every time, on any device
2 dice, 6 sides, seed 42 returns 4 and 3, total 7 — and it returns exactly that pair for every visitor using the identical settings, on any device, because the seeded algorithm removes true randomness from the equation entirely. Bump the seed to 43 instead, and the result changes to a different but equally reproducible pair.
Why a seed, when dice are supposed to be random
The seed is what makes a roll verifiable and shareable rather than a one-off nobody else can check: paste the seed alongside a result, and anyone can confirm the numbers weren't cherry-picked or misreported. Change the seed whenever an actually fresh roll is wanted; keep it fixed to reproduce or share a specific outcome.
What this handles beyond a standard pair of dice
Standard and exotic dice both work here: a pair of six-siders for a classic board game, a single D20 for tabletop RPG attack and skill rolls, or a 100-sided die for percentile rolls used in some systems' critical-hit tables. Up to 20 dice can be rolled at once for games that call for a large handful, like a big pool of damage dice in some RPG systems.
Every face carries an equal chance thanks to a quality pseudo-random algorithm, so rolls stay statistically fair over many repeats, the same way a well-made physical die behaves. For picking arbitrary numbers in a custom range rather than simulating dice specifically, the random number generator offers a wider min/max range and unique-only draws that a fixed-sided die can't represent.
