Please note: The d20 of this set is numbered in a nonstandard pattern to distribute the weight of the numerals more evenly and for aesthetic reasons. If you are superstitious about opposite sides of your d20 adding up to 21, please be aware that the sides of this d20 don't.


IN: 1.739 w x 2.58 d x 0.902 h
CM: 4.416 w x 6.552 d x 2.292 h

@ceramicwombat you make an excellent point! So long as one half of the die does not add up to more than the other half the die it should be tournament legal.

@gooeyideas The insistence that the opposite sides of a d20 add up to 21 is based on superstition and tradition, not reason. A die could be produced with 1-10 clustered together on one side and 11-20 clustered on the other, and often is in what is called a "spindown" style. The numbers could add up to 21 on opposite sides but spindowns are notoriously easy to manipulate to produce a desired result. I placed the numbers on this d20 based on the physical size of the numerals in such a way as to make sure the material was evenly distributed while also making sure that high or low numbers were not more clustered than on a standard pattern d20.

@ceramicwombat you are only correct assuming the player is honest and is rolling the dice for a random outcome. Moving the sides around could create a die were certain types of rolls with a spin or a practiced hand could take advantage of the fact that half the die had a higher than normal probability of rolling a high number. It is mostly a problem for that reason and that is why the two sides must add up to 21 in order to be used in competitive play :) hope this helps! Love the die anyway!

Hello. Why can't you use it this way? Yes, it is traditional that the opposite faces on a die add up to the number of sides +1, but for this die I swapped some faces due to the way the numbers were crowding on the faces in the traditional configuration. In this case, I chose aesthetics over tradition. This does not affect the probability of one number coming up more often than another. My standard and Thorn sets use a standard pattern on the d20 where opposite sides add to 21. The Cage set uses a pattern based on where they look best on the die. The Overstuffed, Spore, and Cage d20s use a distribution from a commercial d20 produced in the 90s where the opposite sides do not add to 21 either.

Great dices, got them in stainless steel - not to heavy, nice to roll but the sum of the numbers on opposite faces is not 21 on the d20! Can't use it this way :(
