Today, D12 dice are mainly found in table-top role playing games and educational math activities, but not in many mainstream games. 3D printers can also “print” any dice shapes that you design with 3D modeling software. Octahedral dice with 8 sides allow for more outcomes than traditional 6-sided dice, but you are unlikely to find these dice in board games either.

When we think of “dice,” what usually comes to mind is a small cube whose six faces are numbered from 1 to 6. For example, archeologists have uncovered small carved dodecahedra in Roman and Greek ruins, suggesting the ancients used these 12-sided shapes as dice. Listed below are the some alternative dice that are widely available in specialty shops and online game stores.

Yet dice are also made in other shapes, allowing for more than six outcomes. These are the most commonly used dice in games of chance and games of strategy that have some component of randomness. For example, Shapeways is an on-demand 3D printing service that allows you to print your own designs in three dimensions, or browse the shops of other users who sell unusual dice shapes. Yahtzee, Clue, Monopoly, Parcheesi, craps, and many other classic games are played with regular 6-sided dice, also known as D6 dice.

Non-cubic dice are often called “Dungeons and Dragons” dice, after the popular game which uses more unusual polyhedral dice shapes to generate a wider range of random numbers. But there’s no reason you can’t use special dice in classic games too.
