Two more tips:
- Buy enough polyhedrons with numbers so you can throw them all at once. Saves a lot of time.
- If you roll a lot of them, like 8d6, group them together so that 2 of them add up to 10, or group same numbers, so it is easier to add all of them together.
- Expert tip: instead of grouping an uneven amount of the same numbers you can take a straight and multiply the amount of dice with the middle number.
Even works for sequences of only even or only uneven numbers (note: the total amount of dice still always needs to be uneven as noted above) .
Example: 2 + 4 + 6 + 8 + 10 = 5 * 6
Edit:
It also works for every sequence where the amount is uneven and all numbers belong to the same residue class modulo n.
Example: 4, 7, 10, 13, 16
All numbers divided by 3 have a residue of 1.
Just some help, because some people claim, people have a hard time adding numbers, while a first grader learns about friendly digits (2 digits that add up to ten).
