Most Dungeon Masters will be familiar with d20 random tables. A d20 table has you roll a twenty-sided die, and then use the result to look up some detail that helps you improvise your world on the fly. These useful tables can be found throughout source books like the Dungeon Master's Guide, and all over the internet.

Today we want to introduce you to a lesser known format, and give you two tables to bring to your own world.

What is a d66 table?

d66 tables work the same as d20 tables - you roll some dice then look up the result - but they require d6's rather than d20's.

To roll on a d66 table, roll 2d6. Use one d6 as the tens column, and the other as the ones column to get your result. For example, if I rolled a 2 and a 4, the result is 24.

d66 tables are popular in OSR games such as Troika! The philosophy behind the use of d6's is one of accessibility: not everyone has access to specialized dice like d20s but almost anyone can find a d6 lying around somewhere. Not to mention the satisfaction of rolling a perfect cube.

A standard version of a d66 table has 36 possible results in it. Here are two tables you can use to generate the title of a book you might find in a fantasy library.

These books will fit perfectly into any fantasy library, such as Strixhaven University, Hogwart's School of Witchcraft and Wizardry, or the secret library in Death House from Curse of Strahd.
