# Generate a Recovery Phrase With Three D8 Dice and Two Coins

Each set of three D8 rolls and two coin flips produces exactly one 11-bit word index. Repeat the five results for 12 or 24 provisional words, then follow the [final-word procedure](https://help.blockstream.com/generate-recovery-phrase-offline).

Use the dice results in order as First D8, Second D8, and Third D8\. Record heads as `H` (value `0`) and tails as `T` (value `1`).

| Result | Value |
| ------ | ----- |
| Heads  | 0     |
| Tails  | 1     |

The word index is calculated as:

```
(First D8 - 1) * 256 + (Second D8 - 1) * 32 + (Third D8 - 1) * 4 + First coin * 2 + Second coin

```

This mapping produces every index from 0 to 2047 exactly once, with every combination of the three dice and two coins represented.
