Product Description

A non-isohedral 9-sided die with no pairs of parallel faces. In other words, when it rests on a face what you see from above is not another face but rather an edge or a vertex.  6 faces are irregular pentagons and 3 are rhombuses.  As with my other sum dice, the value of the roll is the sum of the numbers you see from above.

When it rests on a rhombic face, the value is the sum of the two pentagons adjacent to the up edge.

When it rests on a pentagonal face, the value is the sum of the two pentagons and one rhombus adjacent to the up vertex.

The faces are labeled {0, 0, 1, 1, 2, 2, 3, 4, 6} which via sums generate all the numbers from 1 to 9.  This is probably not a fair die since the probability of the die landing on a pentagon vs. a rhombus is probably not equal.
