About this generator
One tool for the three classic randomizers. Dice mode rolls up to six dice with 4, 6, 8, 10, 12 or 20 sides — covering board games and tabletop RPGs — and shows the total. Coin mode flips up to ten coins at once and tallies heads vs tails. Number mode draws from any range you set, with an optional no-duplicates draw that works like lottery balls: perfect for picking raffle winners or random line-ups. Results come from your browser's random number generator, each outcome equally likely, and nothing leaves your device.
Frequently asked questions
Are the rolls truly random?
They use your browser's built-in random number generator, which is statistically uniform — every face and every number in the range is equally likely. It's more than fair for games, draws and decisions (though not meant for cryptography).
How do I draw lottery-style numbers?
Switch to Numbers mode, set the range (e.g. 1–45), the count (e.g. 6), and keep “No duplicates” ticked — each number can then appear only once, exactly like balls drawn from a machine. Results are sorted for easy reading.
Which dice does it support?
d4, d6, d8, d10, d12 and d20 — the standard tabletop RPG set — up to six dice at once, with the total added up for you. The classic d6 even shows its pip face (⚄).
Are computer-generated random numbers truly random?
Most software, including this tool, uses a pseudorandom number generator (PRNG) — an algorithm whose output is statistically indistinguishable from true randomness. Genuine hardware randomness instead comes from physical processes such as electronic noise. For dice, draws and everyday decisions, a good PRNG behaves exactly like real chance; the difference only matters in cryptography.
The same number came up twice in a row — is that a bug?
No — every roll is independent, so repeats are expected. With a d6, the chance of matching the previous roll is 1 in 6, which happens often. Feeling that a different number is "due" after a streak is the well-known gambler's fallacy; genuine randomness naturally produces streaks and clusters.
Is a virtual coin flip as fair as flipping a real coin?
It can even be fairer. A physical flip is slightly influenced by the starting side, the flipping technique and how the coin is caught, while a virtual flip is a clean 50/50 draw every time. Coin mode here flips up to ten coins at once and tallies heads versus tails for you.
