Role players know this well: there is not only the six-sided die! Perhaps by now almost everyone knows the famous “D20”, or the 20-sided die, used in many role-playing games, but on DecKreative you will find a complete set of special dice already rolled.
The hyphens indicate a “cocked die”: you must draw a new card.
Yes, it is annoying, but it allows you to keep accurate statistics!
You can learn more by reading the article “Mathematics of DecKreative“* by Marco Paoletti.

From upper left:
D%: percentage die. Values in tens, from 00 to 90. Needless to say, it is used to randomize percentages.
D10: values from 0 to 9, where the “0” is usually read 10 (but see exception below). You can pair it with D% to get values like these: 10+1 = 11; 00+7 = 7; 00+0 = 100, and so on…
D4: values from 1 to 4.
D6: the classic six-sided die, with values from 1 to 6.
D8: values from 1 to 8.
D12: values from 1 to 12.
D20: values from 1 to 20 (the die is cocked in this example), widely used in “D20 System” RPGs, such as Dungeons&Dragons.
