The Numbers in Dice Stacking and Balancing Dice

Behold the 120-sided dice, the d120: http://thedicelab.com/d120.html Of course, the d120 is available on Maths Gear! https://mathsgear.co.uk/products/d120-dice Here is the numerically balanced d20 as well. https://mathsgear.co.uk/products/numerically-balanced-d20 If you're in the USA, it might be easier to buy direct from the Dice Lab guys via MathArtFun.

This app doesn't seem to have any links?

Loving the video ! However, I'm not sure if you changed your camera but there is a lot of "picture noise", most noticably on the black background ?

Hey Matt!, I would only add that those D20's are the ones you use in Tabletop RPG's. There is for example, another version that is used for Magic The Gathering (Trading Card Game), which don't have the numbers distributed with the same logic (the sum of the opposites being 21). This is because in Tabletop RPG's the sense of rolling a dice has to be linked with the "equal" probability of each of the possible results, while in Magic The Gathering the dice is used principally for counting. It's not an error, I just wanted to mention that :)

Matt Parker

Still the same old camera! Maybe my lighting was not as good. Once I've saved-up some Patreon money I'll get new camera and lights!

Edit: The best example of what happends when someone makes a comment before seeing the complete video, hahahaha, sorry!

Matt Parker

Indeed! I appreciate you taking the time to comment with those details; and the urgency with which you did so. :]

Sorry couldn't watch your video during lunch break to find any mistakes... Though about mistakes... I have sent you description of math problem I got in my career as Software developer, already sent it in both Patreon PM and e-mail... Did you read it?

Timur Sultanov

Well I took out my 5 d20 (I actually have exactly 5) and checked... Numbers around vertexes do add up to 52 and 53, but I have noticed one interesting thing... All 3 vertexes around 19 add up to 53, while 3 vertices around 20 add up to 52, so distribution is skewed 20 is next to a 1 and 19 is next to a 2 so they have a 2 more vertices which are closer to 20 or 19, and the one closer to 19 adds up to 53, while the one closer to 20 adds up to 52. So it doesn't seem fully fair...

Matt Parker

Yes I had! Sorry, didn't realise I had not replied. Have done so now.

Matt Parker

This is a very good point! I had a look at the distribution of 52 and 53 vertices but decided there was too much to fit in the video already. I'll keep playing around and see if there is a follow-on video in it!

Matt, Love the video! I feel the need to warn you that if you ever play the Pathfinder Adventure Card Game, the dice they provide with the game don't follow the opposite sides add up to n+1 rule with the single exception of the d6. It's very frustrating and somewhat distracting knowing that fact while playing. My suggestion is to bring your own dice. Edit: So glad one can edit these comments. Pressing enter to submit a comment rather than entering a line break is so backward compared to the rest of the internet.

Keronin

Those are indeed the culprits, You can see on the d10 that the 3 and 8 are not opposite each other. I will however, highly suggest playing the Pathfinder Adventure Card Game. I will say this, as you go further on through the box sets (Rise of the Runelords, Skulls and Shackles, Wrath of the Righteous, Mummy's Mask) the game gets more interesting because they've learned how to make better scenarios and characters. However, the later box sets are more complicated and might not be as inviting as the earlier sets to someone who hasn't played before.
