There's another dice puzzle which can also be named "go first" dice.
There exist three dice where A beats B, B beats C and C beats A, statistically speaking. So if you consistently throw A and B, A has a higher chance of rolling a greater number than B, etc.
Kind of rock-paper-scissors, so whoever "goes first" and picks the die will (statistically) lose against a smart opponent who chooses second.
- HelloNurse 4y agoThey are called intransitive dice, and it's just about the opposite problem: as unfair as possible. Wikipedia lists sets: https://en.wikipedia.org/wiki/Intransitive_dice https://en.wikipedia.org/wiki/Intransitive_dice

- VikingCoder 4y agoA friend and I had some manufactured, 20 years ago. We thought about selling them, but had no idea how much interest there would be. My friend did the math to come up with 6-sided ones that had the most uneven odds we could find, and each dice summed to the same number, and all the numbers 1-24 were each used once, and the numbers 1, 2, 3, and 4 were each on a different die, making them easy to identify. We colored them red, green, blue, and then maybe yellow?, if I remember correctly, to also try to make them easy to identify. If I remember correctly, 1 and 3 were fair, and 2 and 4 were fair, which we thought was also neat, because it would help you "prove" that the dice were fair, heh.
