Thirty Dots - thirteen scoring fields, five dice, three rolls and you.

[Zyada]

http://thirtydotsdice.com/

I wrote a (free!) web game I'm calling Thirty Dots. It's based on an old dice game called Yacht, and has absolutely nothing to do with another game sold by Hasbro that might look similar.

I'm putting it here because it has ads, that I hope someday generates a small amount of revenue for me, so please, go, play, have fun and tell someone else if you are so inclined!

[Enderw24]

I gave it a try. Scored 308. It was fun.

Assuming someone was completely unfamiliar with the other "game sold by Hasbro that might look similar" you may want to lengthen the instructions to talk about what each of those categories are, and how they're scored (plus what it takes to hit the pip bonus).

[Bootis]

I like it. Played a few and got 421 I think you should have a final percentile stat that tells me what % of final scores I beat

[Enderw24]

I just got 496. Not sure exactly how, but it gave me 250 for my quinces.

Yep. I have no idea what "quinces" are (five of a kind?), or how to get the pip bonus.

Well if it's similar to another game I played once "quinces" would be when all of the dice have the same number on it and you are supposed to yell out "Yah....I mean Quinces!"

[davidm]

It took me a while to even understand it. I got 162 in my first complete game.

[Wheelz]

A fun little time-killer, but I'll echo the need for more complete instructions.

And to nit-pick, I wonder if the rolling of the dice could be a little more... kinetic? animated? Not sure the word I'm going for, but you know what I mean. Make it a little more visually interesting.

Overall, great job!

[Zyada]

Well, I've added info to the instructions about how the game is scored, and I've added an alert when you finish to tell you how good or bad you did.

I think that's my ADD going, I dislike games that spend a lot of time on animations that don't actually have much to do with the game play. So I don't think that's going to happen.

Although I kind of like the game I've been playing that sprinkles stars along the path the moving piece moves...


Thanks for all the compliments, folks!

[Rachellelogram]

I got a large straight on my first play. I love this game! It's yahtzee!

[Rachellelogram]

Oh also I have adblocker turned on. Do you have a paypal donation link? I'd throw you a couple bucks

[Asimovian]

May I suggest that perhaps you add shading to every other row so it's a little easier to to read across an entire row? I've come close to marking my score in the wrong place a few times when my eyes were a little tired.

I'm enjoying the game.

Fair point, but allow me to expand on my comment. Say I've frozen 4 dice and click to roll the remaining die. If by 1-in-6 chance it falls on the same number as it did the previous roll, nothing appears to happen, and I'm left to wonder if something went wrong and my mouse-click didn't "take." So just some small visual cue that the dice are indeed rolling would be nice, IMO.

Like I said, though, it's a nit-pick. I like the game, and the enhanced instructions are great!

[Malacandra]

291, blew the four of a kind. Enderw24, did you hit several quinces in one game? Each extra one is worth a bonus (as well as counting as a wild hand for the bottom half).

[Enderw24]

yes. I must have hit three quinces in a single game. Never gotten close to that score since.

[ultrafilter]

I just had four quinces in the same game. It's not impossible, but it's so unlikely that I have to believe that the randomization is broken. I took a quick look at your rolling code, and I don't see any obvious bugs, but something is not right.

I agree with this.

I agree with this.

I've noticed that the randomization seems a bit off too. Especially when you reroll two dice and hit the exact same two numbers quite a bit more often than the 1 out of 36 odds.
I just scored 520 points with three quinces in a game. Also somewhat unlikely. But I think what's really the tip off re: the randomness is that MOST games I'm able to hit every single entry (except for quinces) and earn that 37 point bonus for the top half when I'm highly unlikely to perform such a feat with such regularity with five dice in real life.

[gurujulp]

I have not noticed this.

Are the people who aren't having these runs of luck not posting?

Confirmation Bias in action!

[mhendo]

I've played quite a few games over the last week or so, and have never managed more than 1 quinces in a game.

I do sometimes notice the apparent repetition of numbers upon rerolls, but that in itself could just be confirmation bias; you notice when it happens, but forget all the times when it doesn't.

The probability of getting four or more quinces in a single game is on the order of 1 * 10^-8. If I could play one game a minute, I'd have to play for about 200 years before I would expect to see that once. It's not impossible that I just got really lucky, but it's far more likely that the random number generation is wonky.

I'm not sure that is correct- I've read the odds of getting 5 of a kind in a 3-roll turn is around 1 in 22, so getting 4 in a row is only 1 in 230,000ish, so 4 in a game would be much more likely than that. Were you calculating based on getting the 5 of a kinds in one roll only?

Yes. That's a somewhat embarrassing mistake. So the probability of seeing four or more in a game is still on the order of 1/500. It's still rare enough that it makes me wonder about the randomizer, given that I've played a lot of Yahtzee and haven't ever seen more than two, but it's not quite so spectacular.

[Zyada]

Here's some statistics on the quinces...

+------------+----------+
| num_quints | count(*) |
+------------+----------+
|          0 |      438 | 
|          1 |      208 | 
|          2 |       53 | 
|          3 |        9 | 
|          4 |        1 | 
+------------+----------+

709 games have been played, so the one in 500 chance sounds about right.

I wonder how long it will take to get five...

The page is written in javascript (well, 99% of the page), so the actual randomization of the numbers is going to be dependent on the browser, much more than the javascript code itself. I'm not tracking whose on what browser though - Ender, what are you running?

This is actually one of the reasons I wrote this (and am saving stats). I wanted to know what the probability of getting a five of a kind during a game was, because I remember as a kid playing Yahtzee with my grandparents, and it seemed like the grown-ups always got at least one, and often two.

[ultrafilter]

I've added stats on what we'd expect to see from a fair randomizer, and it looks reasonable. I guess I just got really lucky.

+------------+----------+--------+
| num_quints | count(*) | E(*)   |
+------------+----------+--------+
|          0 |      438 | 387.26 |
|          1 |      208 | 239.73 |
|          2 |       53 |  68.49 |
|          3 |        9 |  11.96 |
|          4 |        1 |   1.42 |

I've run it on three systems so far. IE, Safari, and my iPod.

[Enderw24]

Interesting bug/feature.

I marked down "0" for my slot for quince and then rolled a quince. I put it in another slot and at the end of the game, the computer gave me 100 points for this quince.

So by putting it somewhere else, I actually ended up netting 50 additional points.

[Mr Shine]

If Zyada is trying to mimic the Y-word then it should not give the 100 quince bonus unless you have already received the 50 points. As it is now there is no reason to not use quinces as an early discard for a bad hand.

[Half Man Half Wit]

Is there a way to access the statistics from the user level? I'd like that...

Oh, and just now, instead of, as usually, giving a statistic related to the throw just made (which is my favourite feature), it told me 'All troubles you have can pass away very quickly'. Somewhat... disquieting. I love it -- are there any other ominous predictions?

Thirded - I just got that too. And yes, that makes your first quince worth 100 points instead of 50 if you've already zeroed out the quince. It's even worse than Mr Shine says - there is no downside whatever to zeroing out quince straight away!

Hold on a second...

I did just that, but I got another quince later and I only got 100 pts total, see below. Both were five sixes. I put the first in the pips, and the second one by four of a kind.

I think you are still better off getting 100 for the first quince, and having that space available discards, than losing 50 pts for the rarer second quince though.

Well, maybe if you want to go for the rarer ultra high point games, you can play by the normal rules. But if you want a steadier higher point games, use the quince as your first discard.

[I_Know_Nothing]

As far as the randomization goes, it often looks surprisingly not random

On a radio show a while ago I listened to this math professor do this experiment where she would take 2 pairs of students and have one pair flip a coin 100 times and write down the results. The other pair was tasked with trying to mimic a random set of 100 coin flips. She could always spot the fake, because it never had more than 2 or 3 h/t in a row. What seemed perfectly random to the students, at first glance, was obviously not random to the teacher.

Darn thing stiffed me on the fours at the end so I missed out on the top-half bonus, but otherwise it went a treat. I wonder if you scored your second quince on the last turn - the 100-point bonus only shows up on the turn after you make it.

I don't know if there are any more ominous predictions, but there is a small chance you will get some trivia or fortune cookie instead of the stats.

I'm glad you like it.


I reconsidered animating the dice "rolling", so I've added something there. I still didn't want it to impact game play, so the animation only runs while you are pressing down on the Roll button. Note that it is theoretically possible that you could click &release the roll button fast enough that your browser may decide to not change the display.


I'll be happy to add a statistics display - what would y'all like to see on that?

[lost4life]

On an unrelated note, my kids and I have been playing games similar to Yahtzee and I explained that the name was copyrighted. They figured similar games should be called Not-Yahtzee, or Nahtzee for short...You're welcome to the name if you like.
