Dice: generating "Zocchi results" using "normal" polyhedrons
Posted: Mon Jun 13, 2011 5:39 am
Several people have asked this, so here is my simple summary of how to achieve "Zocchi results" with "normal" polyhedrons. (Funny that the d4 is now "normal" -- it sure seemed weird when I was a kid!) In other words, this is how to simulate a d3, d5, d7, etc. with your normal dice.
What's a control die? Several of the examples below require a "control die." A control die means you roll 1d6 along with the first die, and the 1d6 result indicates whether you add to the first die. For example, to simulate 1d24, you can roll 1d12 with a control die. If the control die is even, take the 1d12 result "straight"; if the control die is odd, take the 1d12 result and add 12.
How to simulate Zocchi dice results:
d3: Roll 1d6 and divide by 2.
d5: Roll 1d10 and divide by 2.
d7: (Option A) Roll 1d8 and re-roll on an 8. (Option B) Roll 1d14 and divide by 2 (if you have a d14, which you probably don't if you're reading this, but just in case...)
d14: Roll 1d20 and re-roll on 16-20.
d16: (Option A) Roll 1d8 with a control die (add +0 or +8 depending on the control die). (Option B) Roll 1d20 and re-roll on 17-20.
d24: (Option A) Roll 1d12 with a control die (add +0 or +12 depending on the control die). (Option B) Roll 1d30 and re-roll on 25-30.
d30: Roll 1d10 with a 6-sided control die (add +0 on 1-2, +10 on 3-4, or +20 on 5-6).
Note: There are multiple ways to achieve the Zocchi dice results. The ones noted above are just the simplest ones I've personally come across. If you have an even better preferred method, let us know by posting here!
