What is one die used for?
Ludo, Snakes and Ladders and many family board games use a single die. One die is also the quickest way to decide who starts, pick a random task or choose between 1 and 6.
What are the odds of rolling a 6?
On a fair die the chance of a 6 is 1/6. It takes 6 rolls on average to see a 6, but going several rolls without one is common: the chance of no 6 in 4 rolls is (5/6)⁴ ≈ 48%.
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.

Frequently asked questions
Is every number equally likely?
Yes. Each face from 1 to 6 has exactly a 1/6 chance on every roll, independent of earlier rolls.
What is the average roll of a six-sided die?
(1+2+3+4+5+6)/6 = 3.5.
Why do opposite faces add up to 7?
Standard dice place 1 opposite 6, 2 opposite 5 and 3 opposite 4; this tradition helps keep the die balanced.
Can I use it for Ludo?
Yes. Ludo is played with one die, so this page works as-is.
