Dice Divination
Dice divination is one of the oldest ways of getting an answer: you roll three dice and read the sum, from 3 to 18. Each sum has its own traditional interpretation, and the probability of rolling it can be calculated exactly. The calculator below rolls the dice and shows the sum, how often it comes up, and a link to its interpretation.
How the reading is done
The classic method: the three dice are thrown at the same time onto a flat surface, in silence, after the question has been formulated. The sum of all three is read.
Rules found in most collections:
- Readings are done no more than once a day, and the same question is never asked twice.
- If a die falls off the table or lands tilted, the roll doesn’t count.
- Only the sum counts; individual faces are not interpreted — this is what sets dice divination apart from dominoes, where the tile itself carries the meaning.
The question is framed as a situation — “what will happen with this matter” — rather than as yes or no.
Probabilities of the Sums
Three dice give 216 equally likely combinations. The sums are not evenly distributed, and this can be calculated exactly.
| Sum | Combinations | Probability |
|---|---|---|
| 3 or 18 | 1 | 0,46 % |
| 4 or 17 | 3 | 1,4 % |
| 5 or 16 | 6 | 2,8 % |
| 6 or 15 | 10 | 4,6 % |
| 7 or 14 | 15 | 6,9 % |
| 8 or 13 | 21 | 9,7 % |
| 9 or 12 | 25 | 11,6 % |
| 10 or 11 | 27 | 12,5 % |
The distribution is symmetrical: a sum of 10 and a sum of 11 are equally likely, while 3 and 18 are the rarest. The practical takeaway: you will see the “strong” interpretations of the extreme sums about once in two hundred rolls.
Meanings by Sum
3 luck · 4 disappointment · 5 help from a stranger · 6 loss and gain · 7 gossip · 8 unjust reproach · 9 union · 10 new addition
11 parting · 12 a letter · 13 sorrow · 14 a new friend · 15 caution · 16 a journey · 17 change of plans · 18 complete success

Where the method comes from
Dice are older than almost every other form of divination: astragali — sheep knucklebones with four stable resting positions — were used for casting lots in Mesopotamia, Egypt, Greece and Rome. The six-sided cubic die appeared around the 3rd millennium BC.
Today’s interpretations of the sums do not come from antiquity but from European fortune-telling booklets of the 18th–19th centuries — the same ones that produced “oracles” and dream books. Hence their everyday character: a letter, a journey, gossip, a wedding.
An Honest Look at the Method
A roll of a die is the textbook example of a random event: it was with dice that Cardano, Pascal and Fermat made the first calculations of probability theory in the 16th–17th centuries. The result has no predictive power, and all 216 outcomes are equally likely regardless of the question.
On the other hand, the probabilities here can be calculated exactly, and on this page they are real — you can check them yourself.
