자주 묻는 질문
Are these dice fair and truly random?
Yes. This dice roller uses your browser's cryptographic generator, crypto.getRandomValues, with rejection sampling — it throws away the small leftover range instead of using a plain modulo, so there is no modulo bias and every face is equally likely. If a browser has no crypto generator, it falls back to Math.random and shows a note, so a roll is never blocked.
Which dice can I roll?
All the standard polyhedral dice: d4, d6, d8, d10, d12, d20 and d100. Need something unusual? Type any custom number of sides from 2 to 1000, so this virtual dice roller works as a d3, d16, d30 or any die your game asks for.
How do I use dice notation like 2d6+3?
Dice notation is written as count-d-sides with an optional modifier: 2d6+3 means "roll two six-sided dice and add 3", d20 means "roll one d20", and 4d8-2 means "roll four d8 and subtract 2". Type it in the notation box and press Roll — the notation overrides the buttons for that roll and the total already includes the modifier.
Is anything sent to a server?
No. When you roll a dice online here, every roll happens locally in your browser — no accounts, no ads and nothing is uploaded. You can even install it as an app and keep rolling offline.
Can I roll many dice at once for D&D or board games?
Yes. Set the number of dice up to 100 and add a single modifier to the total — handy for a fistful of DnD dice, a d20 attack with a bonus, or a board-game handful. Each die is shown separately and your last 20 rolls are kept in the roll history so you can check a previous result.
