10 rolled 15% of times and several times during the game, twice in a row

11 9%
12 6%
You need a minimum of 52 rolls to determine if a D6 is fair according to this stack exchange answer.

Put in the dice rolls from your last two games, see what it tells you.

Number 10 rolling 15% means the number 10 was rolled 10 times out of 65 total rolls. This event (10 or more 10s out of 65 rolls) has a probability of 4.21%. Nothing rare what you are posting here...

With only 65 rolls you expect some number to appear far more often than its probability. In your game it was the 10.

Basically i can conclude I am wrong about doubles/triples. So much so I might consider the reverse true...
Of course I care because you initially called us forum users to simply trust your feeling because it was so obvious for you. I wanted to reply that you should simply trust me (as a mathematician) - but it is not a matter of trust. You can simply make tests and look at the numbers.

If BGA does use the cryptographically secure PHP function random_int() - see FAQ - and all their tests and those of game developers, made on millions of random calls show the function does what it is supposed to do - one can simply trust BGA.

Whenever a random number is called by some BGA game the function random_int() does not know what the result is used for. When the next number is called in the same game, hundreds of other random numbers will have been generated by the same function and was used in different games. What you see as a double in your game is not a double for the random function at all. There will be hundreds and thousands of random numbers produced inbetween. The function does not care of your ELO, if you attack a space ship or roll a Catan dice. It does not know that the sum 7 has a special effect in a game of Catan or a 1 has a special meaning for your game.

Have fun with further analyzing your dice rolls. You will find lots of interesting patterns to focus on!
These threads, which keep popping up over and over and over again, are a great illustration of the problem raised in The Death of Expertise. They fall into two broad category: 1) the ones based on the "evidence" that something "feels off"; and 2) the ones where the person at least attempts some kind of analysis.

You can't really do anything to persuade someone who's just going on vibes. But you'd think the second type of person, who is at least attempting to be analytical, could be persuaded.

But nope. They are shown that their sample size is too small, or they used the wrong statistical test, or their probability calculations are just plain wrong, sometimes by bona fide experts in this type of analysis. Yet it falls on deaf ears. For some reason it doesn't sit well with some people that, however smart they think they are, there are people who literally do this for a living and know what they are talking about. It doesn't mean you aren't smart just because you don't understand it, but people take it personally.

You don't necessarily need a PhD in probability theory. But you need some kind of study where your understanding is assessed to make sure you get it. It doesn't have to be a university course, but you need to crack open a physical or digital book and actually work problems.

indeed the most noticeable thing that happened is that 10s often rolled in pair, as I mentioned, not the percentage per se

Out of thousand games played on the platform, basically every game will always have some numbers that does not respect the statistic, I know that.
The interesting thing was to see 10s often rolled in pair, twice a in row, several time

Did I say that was against any statistic? I just wrote it was funny because not only we had numbers rolled outside of the statistic, but also 10s rolled twice in a row several times during the game

LOL you are correct!

In my mind it was clearly sarcastic, being the non-conspiracy take forum and having an exclamation mark at the end!

And I shared it mostly for the consequent rolls of the same numbers, that I think was discuss at a certain point here.

Thanks for calling me out
