Roll Dice Online

Lost your dice? Use your phone

When a die rolls under the sofa during backgammon, Monopoly, Ludo or Yahtzee — or you are short of polyhedral dice for Dungeons & Dragons — your phone becomes the dice. Zar Salla puts one die, two dice, three dice and every common RPG die on a single screen.

Each roll is saved with its total in your on-device history, so there is no more “what did you just roll?” and at the end of a long game you can see how often each number came up.

How do I roll?

• The dice roll automatically when the page opens. To roll again, press “Roll Dice”, tap the dice or hit the space bar.
• On a phone with “Shake to roll” enabled, just shake your device.
• Pick a die type from “Dice Types” in the top menu or the d4 – d20 tabs: roll 1–4 of a d4, d8, d10, d12 or d20, or 1–6 six-sided dice.
• Every roll is saved to “Roll History” with its total, and the “Stats” tab shows how often each face has come up.

Which dice do I need?

• One die (1d6): Ludo, Snakes and Ladders, deciding who goes first.
• Two dice (2d6): backgammon, Monopoly, Catan and other two-dice board games.
• Three dice (3d6): classic D&D ability scores and 3d6 systems such as GURPS.
• Five dice (5d6): Yahtzee and Generala.
• Six dice (6d6): Farkle (10,000) and big damage rolls.
• d4, d8, d10, d12, d20: Dungeons & Dragons and other tabletop RPGs.

Is Zar Salla a fair dice roller?

Yes. Results come from your browser’s cryptographic random number generator (Web Crypto API, crypto.getRandomValues), and rejection sampling gives every face exactly the same probability. Nothing is sent to a server, nothing is decided in advance and no roll depends on the previous one.

Just like real dice, short streaks of the same number are normal. As you roll more, each face’s share gets closer to the expected value — you can watch this yourself in the “Stats” tab.
