Traditionally, 1d100 is rolled by rolling two d10s, with one of the dice used for the tens’ place and the other used for the ones’ place. But it is possible to buy a hundred-sided d100 die; they look very close to spheres, and must necessarily be rather large, but they work.
A friend of mine was wondering, has anyone done that, but with the sum of 2d10 rather than two d10s used to create a d100? That is, a hundred-sided die with all the possibilities of the total of 2d10, in the proper distribution. It would range from 2–20. There would be one side labelled 2 (representing 1 + 1) and another labelled 20 (representing 10 + 10), covering the minimum and maximum rolls. There would be two sides labelled 3 and another two labelled 19. The interest is basically the same as the usual d100: you could just read off the die rather than performing some (admittedly simple) math.
My guess is no, because 2d10 is used much less often than 1d100, but it’d be interesting.
