Random Dice Roller
Roll any dice, any number of times.
Roll anything from a d4 to a d100 — or type a custom side count up to 1,000 — with up to 20 dice per roll and an optional modifier added to the total. Handy for D&D ability checks, replacing a missing board-game die, or classroom probability experiments. Each die is rolled independently with unbiased Web Crypto randomness, and every individual result is shown alongside the sum.

अक्सर पूछे जाने वाले प्रश्न
Can I roll dice that don't physically exist, like a d3 or d1000?
Yes. Choose Custom as the die type and enter any side count from 2 to 1,000. The roller treats it exactly like a standard die.
Does the modifier apply to each die or to the total?
The modifier is added once to the sum of all dice, not per die. Rolling 2d6+3 means both rolls are added together, then 3 is added.
Can I see each individual die, not just the total?
Yes. Every die appears as its own chip above the total, and the CSV export lists each roll on its own row along with the die type.
Are the rolls biased on unusual side counts?
No. The roller uses rejection sampling on crypto.getRandomValues, which avoids the modulo bias that naive random code introduces, so a d7 or d100 is as fair as a d6.
How many dice can I roll at once?
Up to 20 dice per roll, enough for an 8d6 fireball or a dice-pool system. Each result is shown individually, summed, and saved to your roll history.

- Best of three: when a single coin flip feels too harsh
One flip decides in half a second, but sometimes a binary call feels too abrupt to accept. Here's why flipping an odd batch and taking the majority changes nothing about the odds — and everything about how the loser feels about it.
- The dice math a digital roller gets right (and a physical set hides)
A lost d6 or a remote D&D session is the obvious reason to roll dice online. The less obvious reason: seeing the actual math of 2d6 vs. 1d20, and how a flat modifier changes your odds more than most players expect.
- Assigning fair raffle ticket numbers with a random number generator
Naming a winner by name feels arbitrary; drawing a number out of a known range feels provable. Here's when to reach for a numeric random draw instead of a name-list picker, with worked examples for raffles, lotteries, and sampling.
