I&#x27;m not really sure what the argument here is.<p>Given the fact that each vertex of the die has 10 triangles that sum to 595, and including a non-malicious roll against a backdrop, I don&#x27;t see how this die is any more or less fair than a normal d6 (which I believe we can concede is &#x27;fair&#x27;).  After all, if you want to cheat at dice, then you can cheat at dice regardless of any common understanding of &#x27;fairness&#x27;.<p>In particular, I was responding to the following comment, &quot;If its too large, it may only reach a portion of the neighboring values at each bounce&quot;.<p>My argument was only that if you drop the dice from say a distance of 3&quot;, and it doesn&#x27;t bounce then at a minimum, you wouldn&#x27;t get a large grouping of numbers that are all near each other (Even if you were able to somehow pick a specific &#x27;vertex&#x27; to always land up, you&#x27;re going to have a total average of 59.5).  In other words, you couldn&#x27;t drop the die such that you could guarantee a range of 110-120 (which you could for example do on a MTG spindown die, which is fair but not uniform).  In other words, even if there is no bounce, a typical rolling of the dice would be &#x27;good enough&#x27; for say a pen and paper RPG, and even just dropping it without the bounce is likely enough to give non-Vegas levels of &#x27;fairness&#x27; even if &#x27;it may only reach a portion of the neighboring values at each bounce&#x27;.
