Meet the D120! That’s right, it’s a 120-sided die, and it could be the answer to all your tabletop RPG needs. It certainly is the largest die I’ve ever seen and, according to the inventor, it’s the largest anyone ever will see!
Made by The Dice Lab, each of the 120 faces is an elongated triangle, and features the most faces possible “on a mathematically fair die.” I don’t get math — I agree with Barbie: “Math is hard!” — so I figure there must be something about die with more sides that causes them to roll unfairly or something.
If there’s any doubt about what was rolled, simply spin the die in place; the uppermost number is the one that doesn’t move.
This video explains it all (including the complicated math):
The opposite faces add up to 121, and the numbering has been calculated for “perfect numerical balance” all around the die — meaning the numbers are spread evenly, so big numbers aren’t clumped together.
You can get D120 (as well as other iterations of gaming dice) from The Dice Lab’s merch page for $12 each or five for $50.
