4d4 total distribution
Four d4 have 256 equally likely outcomes. The extreme totals (4 and 16) can each be made only one way, while 10 can be made 44 ways — so the total clusters in the middle and extreme results are rare.
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.
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.
