Dice rolls and card shuffles only mimic randomness too, they're deterministic processes (as far as our current understanding or physics goes). In practice, both are as random as it matters (except if one shuffles poorly, or uses loaded/broken dice, or tries to cheat).

Space base..just now... 3 player Arena mode game... 83 turns... of those 83 dice rolls... 12 appeared 5 times... and 7 appeared 4 times. In WHAT WORLD of dice does Double SIX appear more times than 7???

It's a low probability yes, but how probability works is that all outcomes will eventually come up. Just because something is unlikely doesn't mean it NEVER happens, it means it happens rarely, but that means it does happen, somewhere, sometime. If you truly think something is wrong with the dice, analyse the distribution over say 100 games and see where it ends up. Even at that point, 100 games is not that large of a sample, given that there are almost 1700 games of it going on right now (and so you should then continue with a larger sample).

I'm also curious why you think a dev might code it to bring up less popular throws more often. For it to benefit a specific player, it needs to be able to tell what cards that player has (and compare to other player's cards to determine the optimal rolls). That's a huge amount of work compared to asking it to give you back a random dice roll from 1-6.

Have you actually tried calculating the probability of this event before crying about conspiracies?

Is it time for another one of these threads already? I thought we just had one, you need to wait another 3 months for the next one.

In a previous thread( https://boardgamearena.com/forum/viewto ... 34#p160834 ), user Silene made a simple program I absolutely adore: https://onecompiler.com/python/3zvmdjamm

It generates a 10x10 grid of 56 rolls with two dice. The majority of these do NOT have regular distribution curves. Then is sums them all up at the bottom and with 5600 rolls you get a very regular distribution curve. I just ran it and easily found one of the samples with two 7's and three 12's, so more double sixes than sevens like you asked. The code is visible so you let me know if you see any flaws in it.

Also, what are you suggesting? That the Randomness algorithm in Space Base is flawed? That's easy to prove: For your next 5 games record the dice rolls and see if 12s keep getting rolled more than 7. The trick is you have to decide to record roll results before you start the game, otherwise you're getting an outlier and then deciding that game's results are representative.

In any real world.

What is the probability of any particular person winning the lottery? And yet, someone wins the lottery every week (for some types of lottery at least).

There's a 1 in 500 chance of this happening and there's 1700 space base games in progress as I type this.

If this never happened then I'd be more suspicious of the RNG

You don't even need to do this.
Quite often games like backgammon show player stats and dice rolls. It should be easy to see if the overall averages are off.

Threads like this are exactly why they show those stats. Unfortunately people who don't understand the RND() function also won't understand that all these games generate dice rolls the same way.

In a world where players can choose to take the roll 4-3 as a 7 or as a 4 and a 3 separately.

This has come up before. Space Base lets you choose to take the combined roll or the two dice singularly. The results you see show what people selected, not what was rolled.
