Option to select a different dice system
How does your random number generator work? Are the seeds randomized enough? Very often it seems that the same numbers are being rolled multiple times, 3, 4, even 5 times within the first 6 or 7 rolls.
If there are 50 rolls in a game, the chances any number is rolled 3 times consecutively at any points in the game is 3.8% however it seems like it happens every other game.

2sheepmachineI had a game with only two sixes rolled the entire time. Right after another game where nearly no sixes were rolled. So it does seem like the rng is broken.

bric22I also feel like the dice rolling doesn't work great.

KliphIt seems like this happens all the time when playing in real life with actual dice too though. If the admins say it's truly random, I believe it. It's just the way the dice roll sometimes. If the odds came up exactly as often as they are expected to, that wouldn't be random.

bThe best and I think only way to test this is to list roll distribution of ALL games over long time period. Then we can look past small sample size (i.e. games that you play in). Will add global roll distribution as new feature request. Would be interesting to see resources generated etc as well

MKJust played a game in which 10 was rolled ONCE the entire game, and 11 was never rolled. But 5 and 9 came up constantly. I understand probabilities, but the skew was kind of ridiculous.

player MergedI don't think this tells the full story of whether the dice are truly random (or somewhat fairly distributed). Easily can have a game where 2 rolls 5 times and 9 doesn't roll until 80% of the way into the game. When those numbers roll is relevant to whether this game is working.

MatiasThe dice is working as it should. But random means you'll have games out of the ordinary. So while the average game will roll (statistically) more 4s than 2s and more 7s than 8s this won't be the case for most games. Most games will be random meaning that some numbers will be rolled more than expected taking away from numbers that are rolled less than expected.
This is normal and is also the experience you often have when playing the board game.

Guy IncogneatoI don't know, it seems pretty rigged. Playing against a robot player, the robber always gets placed on my number, which then gets rolled 3 of the next 4 turns, then the bot moves the robber to a new number, and again, said new number gets rolled several times. All the while i get no new resources AND get all my existing ones stolen. I played a game where the 7's where 38 to 4 in favour of the robot player.

Alex BruskiIt would be nice to have the option to "not have 7's rolled at all" and "not have unused hex numbers" roll either. Would speed up play with two player games and make for a friendlier game. I would also like a no robber option as well. That would allow no robber but still allow card loss with a 7 roll.
Having selectable options makes it available to have the choice to play the game the way you want to, just like you can do with a board game.

player Merged(and yes, I know how statistics work... and you can look at hundreds of roles to prove it "works" but when it takes 2030 rolls for top numbers to appear once, something is out of balance.)

playerJust played a game where 3 and 9 rolled zero (0) times the entire game. 10 rolled more than 6 or 8 (same game), 4 just as much as 6 and 8.
I think the problem here is if you look at too much data it looks like this RNG works, but on a game level is sucks. Just play a game where the dice roll abnormally for the first 1020 rolls and the game balance is unrecoverable (it doesn't mean anything when what should be a common number suddenly rolls well in the last handful of turns)

Alex LauYou could try a sudo random. In the original Tetris, the prices where not truly random and was instead random in group of two sets. You can do something similar with having 2 sets of number pair in a normal distribution (is. 11, 12,...66) thrown in an list and have the game pull them out one by one and only refill the bag when it’s fully empty.

player MergedJust played a game where 4 and 10 dominated the game, and 7 rolled 1x (once!).

25 Feb, '20
Connor MergedMy experience with random dice rollers either on apps or just online has been very similar. The algorithms are awful. Nothing beats rolling the dice in real life.

17 Mar, '20
hooahGames where a roll dice don't happen happen in real life too. It sucks and is very frustrating when your 4/5/6 resource never happens and your entire strategy crumbles, but that's the game IRL too

19 Mar, '20
Alex Bruski MergedI am working on getting balanced die rolls installed to alleviate the problems... just have patience. I do play 1 on 1 with the bots myself. It plays the same as 1 on 1 against good humans.

23 Mar, '20
HoldtheMayoNot sure if this was mentioned already but does it seem to anyone that a number could not have been rolled all game but as soon as the robber is placed on it then it is rolled every other roll. I'm sure it's just coincidence but I feel like it happens more times than not.

23 Mar, '20
player MergedJust wait until you play the games where 6, 7, 8 never rolls and 4 and 10 roll repetitively, ugh. It's not like I hate 8 rolling a lot (which hurts if you aren't on it), it's when the other high probability numbers in that same game fail to roll at all yet low probability numbers dominate. [And "the dice work" / "that's how randomness works" is the response...]

Alex BruskiI wrote a new dice class  Upon generating 40 or so files with 100 rolls each and analyzing them all, there is still a significant amount of error in the distribution just because of the addition of two randomly generated dice rolls. It is a little better than what was being achieved before, but it still is not what I would like it to be. I will work on it some more to find a way to get a better distribution without making it easy to predict the next roll result.

24 Mar, '20
Alex BruskiI have a new method of generating two dice rolls and insuring that the rolls are not outliers on the standard dice distribution. I have tested this method thoroughly, and it really does a nice job for any reasonable number of rolls that would be used in a game. I create an array with the expected percentages for each roll (2&121/36, 3&112/36, 4&103/36, 5&94/36, 6&85/36, 76/36) then I generate two die rolls and add them. I check the % of that roll against array and reroll if it is high.

24 Mar, '20
Alex BruskiThe roll is only used in the game if it's percentage of occurrence is at or below the expected probability of that number. Example: if on the 35th roll, die one is 5 and die two is 1, and a six has been rolled 4 times in the last 34 rolls, then the die rolls of 5 and 1 are used in the game. If the 36th roll comes up as 3 and 3, that roll would be rejected and rerolled, as the number six has now been rolled 5 out of 36 times. 6/36 is greater than the expected 5/36 and thus rejected for use.

25 Mar, '20
DilI had a game where a 6 was rolled four times. I know that it is normal distribution, but please check the algorithm for creating the 6 combination for the mean or standard deviation of the distribution.

Out of 75 turns in this game, the dice rolled six 19 times, eight 2 times and ten 3 times. Two and Twelve were rolled 5 and 4 times respectively, both more than twice of eight. But hey the dice is random. 
29 Mar, '20
ZyatonMikeIsMyIke, you did your math wrong. The chance of rolling 3 in a row is much higher than that. The probability of rolling 3 in a row of any given dice sum in a given game is somewhere near 57%, so it actually should happen every other game on average.
Here's the probability of getting 3 7s in a row somewhere in 50 rolls: https://www.wolframalpha.com/input/?i=probability+of+streak+of+3+successes+out+of+50+trials+with+p%3D6%2F36
It's 17%. 
29 Mar, '20
ZyatonJust about every programming language has a good pseudorandom number generator. Implementing this is fantastically easy, and the programmers would have to do work to mess this up.
Just post the one line of code they use to do the dice rolls, everyone can see that it's obviously correct, and close this as will not implement.
It's well documented that humans will see patterns in randomness no matter what, and humans are really bad at understanding randomness.

Alex Bruski MergedWhen combining two random 6sided dice by adding their values to get the dice roll, a lot of variation enters into the roll distribution. If you check it over 400 or more rolls it is very close to the proper distribution. When under 100 rolls are evaluated, the distribution will have a lot of variation. I have coded a fix for this problem and submitted it to the developers of the game, but it has not been implemented yet.
continued... 
30 Mar, '20
Alex Bruski MergedIt consists of 13 lines of code that checks the frequency of the current roll against the normal distribution of expected dice rolls and only uses the roll if it falls within that distribution. If the dice roll would be outside of the expected distribution, it just rerolls, then checks again. When it finds a roll that does fall within the distribution frequency, then it uses that roll and records it in the current roll frequency statistics.

IvanI have had perhaps 10 games in a row where tens or 11s have been thrown more than twice as often than 7s and 8s.
If this will not be fixed i think people will stop playing. 
02 Apr, '20
Tanweer SinghYup agreed, there is definitely something up with the algorithm. 6 is supposed to be one of the most common numbers but I'm consistently seeing that it hardly gets rolled. I've just stopped building near 6s..

02 Apr, '20
Stuti BThe dice roll needs to be fixed. 6 and 8s come way lesser than they should in every game. This is after playing 1520 games. We all as a group have been noticing very odd behavior from the dice rolls. Please try and fix or introduce event cards asap. This really affects the game experience. Most games seem too unfair and biased and not at all according to the probability.

03 Apr, '20
MatiasSorry, but I disagree with the premise the the rng isn't working appropriately. I've played on this site for a year and I've never thought that the dice wasn't random. What I believe people don't like is the fact that it's random. They want the dice to be predictable. There is a variable to the real boardgame where the dice is replaced by number cards. With that system you always know the amount of each number will be drawn just not exactly when. Instead of suggestion that the dice shouldn't be

MatiasThe dice alternative is called Catan: Event cards and introduces a deck of 36 cards one for each dice combination. https://boardgamegeek.com/boardgameexpansion/20038/cataneventcards

03 Apr, '20
MatiasThe alternative reduces the luck aspect of the game. You can suggest that the devs add that to the site if you don't like luck of the dice. But I personally think that it is what makes Catan interesting.

04 Apr, '20
Alex BruskiI would like to see the distribution controlled dice routine tried out on the test site. I have already written the code, it is under 15 lines. Let's give it a try and see what people think... it is really easy to go back to what it is now, if people don't like the result. Let's try it and see what people think. What is there to lose, satisfied gaming is what is to gain!

05 Apr, '20
KyrinaeWe pretty much exclusively play this game in real life (catan) and I have only been playing on Colonist since the Covid stuff. Over the course of 12+ real life games with 56 people, we have rolled a 7 less than 20 times. Total.
Just this ONE last game on Colonist with 3 people and a bot, 7 was rolled 20 times. The previous game 13 times. Out of the 7+ games on Colonist, every game has had OVER 10 7's.
Please either fix the 7's or make a no 7's option, its just depressing at this point. 
05 Apr, '20
Sergio7 is rolled much more often than other numbers, everytime

05 Apr, '20
Elai will stop playing colonist.io just because of 7s. in every 34 terms, its 7. it can not be random because after any game when i look at the statistics, its 7 that the most diced number. i dont believe the algorithm works fine.

05 Apr, '20
Alex BruskiSeven should be the most rolled number. **But**
7 should only roll around 6 times every 36 rolls.
6 & 8 should only roll around 5 times every 36 rolls.
5 & 9 should only roll around 4 times every 36 rolls.
4 &10 should only roll around 3 times every 36 rolls.
3 &11 should only roll around 2 times every 36 rolls.
2 &12 should only roll around 1 time every 36 rolls.
Check the dice statistics after each game. The distribution of numbers is all over the place. 
07 Apr, '20
sikander MergedThere are numbers which are absurdly rolled over and over and over and over again in every game I've played.

10 Apr, '20
Alex BruskiI propose that *Fun Mode* gets multiple dice options. Then the *purists* who like their wonky random only dice rolls can have them, and those of us who want a proper distribution of dice rolls can have what we want as well. Any game type *should* be able to be played in the Fun Mode Section. I can not see why anyone would object to this proposal???

togIf you do want to improve the randomness, maybe consider replacing math.random() with Alea: https://github.com/nquinlan/betterrandomnumbersforjavascriptmirror.

AndriiCome on, leave it as is! It's like in real life now, I love it.

19 Apr, '20
StroomNo need to change this. I guess it is OK to have it as an option but it should never be the default. If players want a less RNG based game, there are hundreds of board games out there.
