Probabilities of two-dice totals
Two dice have 36 equally likely outcomes. A total of 7 can be made six ways (1-6, 2-5, 3-4, 4-3, 5-2, 6-1), so it is the most likely total. 6 and 8 come up five ways each (13.89%), while 2 and 12 have only one way each (2.78%).
The chance of any double is 6/36 = 1/6 — about one roll in six.

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.
