I have made up a game that requires 7 tetrahedral dice (4 sided dice). You start by rolling all the dice and all the dice that land on 1 are pushed aside. you roll all the remaining dice and do the same thing until all dice are on 1. the goal is to get the least amount of rolls for all the dice to land on 1.
I tried to get an average on all the number of rolls but the average keeps changing and never stays on one number :( I have also added a high and low (a.k.a. maximum and minimum)
