Each d8 represents an Aett of the Elder Futhark. Each die has 24 angles and represents the whole Rune row. Freyr's Aett has the Runes Fehu through Wunjo and the numeric values on the Runes on any two opposite side is 9. Hagal's Aett contains the Runes Hagalaz through Sowillo and the sum of opposite sides is 25. Tyr's Aett contains the Runes Tiwaz through Othala and the sum of opposite sides is 164. The sum of all Aetts is 300. The following table shows the pairs and sums:
Frey'rs Aett | |||||
Rune Pairs | Fehu & Wunjo | Uruz & Gebo | Thurisaz & Kenaz | Ansuz & Raidho | |
Numeric Value and Sum | 1 + 8 = 9 | 2 + 7 = 9 | 3 + 6 = 9 | 4 + 5 = 9 | 4 * 9 = 36 |
Hagal's Aett | |||||
Rune Pairs | Hagalaz & Sowillo | Nauthiz & Elhaz | Isa & Pertho | Jera & Ihwaz | |
Numeric Value and Sum | 9 + 16 = 25 | 10 + 15 = 25 | 11 + 14 = 25 | 12 + 13 =25 | 4 * 25 = 100 |
Tyr's Aett | |||||
Rune Pairs | Tiwaz & Othala | Berkano & Dagaz | Ehwaz & Ingwaz | Mannaz & Laguz | |
Numeric Value and Sum | 17 + 24 = 41 | 18 + 23 = 41 | 19 + 22 = 41 | 20 + 21 = 41 | 4* 41 = 164 |
All 3 Aetts add to 300 |
I searched all round online and the first mention I found that sounded similar to my 3d8 was on Witch School. The post popped up in a google search and reads:
Does anyone use rune dice? I just purchased a set of futhark 3 dice which are 8 sided. They haven't arrived yet for UK, I live in the USA. So I am not sure how to read them. My intial thought is a 9 rune spread, with 3 rolls of the dice. I am very connected to Dragons and I expect my Dragon guides to give me push in the right direction. But was hoping this group might have some information.Brightest Blessing, Runestar
So I joined the website just to ask about these Rune Dice. No answer yet.
I have been making the dice in paper and clay since October of last year. I would really love to make them of wood, but I have no idea how to go about that.
A couple of hours ago I found a patent in google patent search. It's the exact same layout as I have. I can't find them for sale anywhere, though. You can find it HERE.
Anyway, I have been making my dice from Premo Sculpey clay. I just knead them until they feel and look right, bake them and then sand them down and paint on the Runes with paint markers.
As you can see from the picture, I've worked everything out on paper first before marking the Runes on the clay dice. I made my dice extra large because I like the over-sized feel.
If you would like to see what the 3d8 Rune dice look like, print this out, cut and fold. I'm sure you can figure it out.
Of course, the first thing that one tries to work out is a system of divination, but I am now playing with concepts for true Rune Games. I'm working on unique dice notation and figuring out the probability distributions. Is there already a Beowulf RPG? I need to do more googling.

Addenda: On further inspection, the patent does not match my dice in the Rune forms or in their pairings based on Runic Numbers.
7-2-2012: I just found these on Etsy. They also do not match my design, but they look cool. No, I don't know this person and I won't make any money if you buy from him (seems to matter to some people).
