Here’s how you can play D&D with just that little six-sided dice that came in your monopoly box.
(I think I”ve got the approach with the fewest expected rerolls, there are still going to be some but it will do in a pinch (or you could just buy my dice app I guess…)) #Dice #DnD #ttrpg
To be clear, I do not recommend doing this. It will slow the game down a bunch.
But, the math works, the results will be fair.
Okay so I thought of a way to reduce the expected roll to 1.333etc when trying to get a d4 result, but it’s not as straightforward to describe and complicates the process. OTOH it does also cap the rolls for that part to 2.
Basically:
If you roll 1-4, that’s the result, if not remember the result and roll again.
If the second roll isn’t 1-4, then compare first and second rolls:
5,5 = 1
5,6 = 2
6,5 = 3
6,6 = 4
Since 6^N always ends in 6, it can never be cleanly divisible by 5, so there is no way to guarantee a map.
I wondered about d7 whether that’s possible with d6 and guaranteeing number of rolls, because 7xN sometimes ends in 6, but I tested up to 5000d6 without luck. (2/2)
