What is an online dice roller?
An online dice roller simulates rolling physical dice using a random number generator. Choose your dice type — from a 4-sided d4 to a 100-sided d100 — and the tool picks a fair, unpredictable result for each die. Every face has exactly the same probability, just like a real die, making virtual dice perfect when you don't have physical ones at hand.
Coin flip and dice roller online, in one tool
Most sites make you open two pages — one for dice, one for coins. This free coin flip and dice roller online keeps both on a single page: roll d4, d6, d8, d10, d12, d20 or d100 (up to 10 dice, individual results plus total), then switch to the Coin Flip tab for a cryptographically fair 50/50 flip. No download, no signup, no app — it runs entirely in your browser.
Dice types and where they are used
- d6 (six-sided): the classic die — Monopoly, Ludo, Yahtzee, and most board games.
- d4, d8, d10, d12: tabletop RPGs like Dungeons & Dragons use these for damage, healing, and checks.
- d20 (twenty-sided): the iconic D&D die for attack rolls and saving throws.
- d100 (percentile): generates 1–100 for probability tables and random events.
Roll up to 10 dice at once — the tool shows each individual result plus the total, exactly what you need for multi-dice game mechanics.
Coin flip: the fairest decision maker
When two options are equally good, a coin flip decides without bias or argument. Our flip uses your browser's cryptographically strong randomness, giving heads and tails a true 50/50 chance every time — fairer than most physical coins, which can have tiny weight imbalances. Use it to choose who goes first, settle friendly debates, or pick between two restaurants.
How do I roll dice online without downloading an app
You can roll dice online without downloading an app in three quick steps: open this page in any browser (phone, tablet, or computer), choose your dice type — d4, d6, d8, d10, d12, d20 or d100 — and tap Roll. No install, no storage space, no app updates; it works in Safari, Chrome, and every other modern browser. Each roll uses your browser's Web Crypto randomness, so the results are fair and unpredictable every time.
Are virtual dice really random?
Yes, for games and decisions. This roller uses the Web Crypto API, the same strong randomness browsers use for security. Results are unpredictable and evenly distributed across all faces. Like all software RNGs, it is not certified for regulated gambling — but for board games, classrooms, RPGs, and everyday choices, it is as fair as dice get.
