This is a three-sided die (d3) shaped like the digit 9. The shape is similar to my
"Penrose" d3.
Note, this die is intended as a d9 - it is labelled {0, 3, 6}. To generate random numbers from 1 to 9, roll this die and a standard
d3 and sum the results.
This is part of the
"Numbers" dice set, a set of d1 through d9 shaped like the numerals themselves.
