A d66 roll is made with two regular six-sided dice. The first die gives the tens digit and the second die gives the ones digit. For example, a roll of 3 and 5 gives a result of 35. A roll of 6 and 1 gives a result of 61.

What Is d66?
d66 is a dice method that creates results from 11 to 66 using two normal six-sided dice.
You do not add the dice together. Instead, read one die as the tens digit and the other die as the ones digit. This creates 36 possible results, which makes d66 useful for compact random tables.
How to Read a d66 Result
A d66 result is not the same as adding two dice together. You do not add the dice. Instead, read them as two digits.
| First Die | Second Die | d66 Result |
|---|---|---|
| 1 | 1 | 11 |
| 2 | 4 | 24 |
| 3 | 6 | 36 |
| 5 | 2 | 52 |
| 6 | 6 | 66 |
This gives you results from 11 to 66, with 36 possible outcomes total.
What Is d66 Used For?
d66 tables are useful because they create 36 possible results using only two normal six-sided dice. That makes them easy to use at the table, easy to print, and easy to build into referee tools.
Traveller referees often use d66 results for quick inspiration, including:
- Random names
- Patron encounters
- Starport complications
- Rumors and leads
- NPC traits
- Shipboard problems
- Trade goods or cargo details
- Mission complications
- Worldbuilding prompts
- Encounter twists

Why Referees Like d66 Tables
d66 tables are fast. They do not require unusual dice, special apps, or complicated math. That makes them especially useful during live play when the referee needs an answer right now.
They are also easy to organize. A d66 table can hold enough results to feel varied without becoming too large to use. That makes d66 especially useful for random names, quick NPC details, small complications, improvised encounters, and short mission prompts.
For Traveller and other science-fiction RPGs, d66 tables are a good fit because they can add detail without slowing the game down. When the crew asks who is waiting in the starport bar, what went wrong with the cargo, what the customs officer wants, or what name is on the shipping manifest, a d66 table can keep the session moving.
Use d66 Results in Your Traveller Game
Here are a few quick ways to use a d66 result during a session:
- Names: Roll once for a first name and once for a surname.
- NPCs: Roll once for a role, once for a motive, and once for a complication.
- Encounters: Roll once when the crew enters a new location or starts asking around.
- Complications: Roll when a plan succeeds but creates a new problem.
- Rumors: Roll when players look for information in a starport, bar, market, or local net.
- Patrons: Roll when the crew needs a job offer, suspicious employer, or unexpected mission lead.
The best d66 tables are specific enough to help but flexible enough to improvise from. A result should give the referee a useful push, not lock the entire scene into one narrow outcome.
Traveller Referee Tool Ideas for d66 Rolls
A d66 roller becomes more useful when you pair it with a table that answers a real referee problem.

| Need a name fast | First names, surnames, ship names, company names | A broker, pilot, passenger, or customs officer gets a name instantly. |
| Scene needs a twist | Complication tables | The cargo is legal, but someone else claims ownership. |
| Players ask around | Rumor or lead tables | A dockworker heard the missing scout ship changed transponder codes. |
